**Full documentation for REST framework is available on [http://django-rest-framework.org][docs].**
Note that this is the 2.0 version of REST framework. If you are looking for earlier versions please see the [0.4.x branch][0.4] on GitHub.

# Overview # Overview
This branch is the redesign of Django REST framework. It is a work in progress. Django REST framework is a lightweight library that makes it easy to build Web APIs. It is designed as a modular and easy to customize architecture, based on Django's class based views.
For more information, check out [the documentation][docs], in particular, the tutorial is recommended as the best place to get an overview of the redesign. Web APIs built using REST framework are fully self-describing and web browseable - a huge useability win for your developers. It also supports a wide range of media types, authentication and permission policies out of the box.
If you are considering using REST framework for your API, we recommend reading the [REST framework 2 announcment][rest-framework-2-announcement] which gives a good overview of the framework and it's capabilities.
There is also a sandbox API you can use for testing purposes, [available here][sandbox].

Content negotiation is the process of selecting one of multiple possible representations to return to a client, based on client or server preferences.
## Determining the accepted renderer
REST framework uses a simple style of content negotiation to determine which media type should be returned to a client, based on the available renderers, the priorities of each of those renderers, and the client's `Accept:` header. The style used is partly client-driven, and partly server-driven.
1. More specific media types are given preference to less specific media types.
2. If multiple media types have the same specificity, then preference is given to based on the ordering of the renderers configured for the given view.
For example, given the following `Accept` header:
application/json; indent=4, application/json, application/yaml, text/html, */*
The priorities for each of the given media types would be:
* `application/json; indent=4`
* `application/json`, `application/yaml` and `text/html`
* `*/*`
If the requested view was only configured with renderers for `YAML` and `HTML`, then REST framework would select whichever renderer was listed first in the `renderer_classes` list or `DEFAULT_RENDERER_CLASSES` setting.
For more information on the `HTTP Accept` header, see [RFC 2616][accept-header]
---
**Note**: "q" values are not taken into account by REST framework when determining preference. The use of "q" values negatively impacts caching, and in the author's opinion they are an unnecessary and overcomplicated approach to content negotiation.
This is a valid approach as the HTTP spec deliberately underspecifies how a server should weight server-based preferences against client-based preferences.
---
# Custom content negotiation
It's unlikely that you'll want to provide a custom content negotiation scheme for REST framework, but you can do so if needed. To implement a custom content negotiation scheme override `BaseContentNegotiation`.
REST framework's content negotiation classes handle selection of both the appropriate parser for the request, and the appropriate renderer for the response, so you should implement both the `.select_parser(request, parsers)` and `.select_renderer(request, renderers, format_suffix)` methods.
## Example
The following is a custom content negotiation class which ignores the client
request when selecting the appropriate parser or renderer.
class IgnoreClientContentNegotiation(BaseContentNegotiation):
def select_parser(self, request, parsers):
"""
Select the first parser in the `.parser_classes` list.
"""
return parsers[0]
def select_renderer(self, request, renderers, format_suffix):
"""
Select the first renderer in the `.renderer_classes` list.
"""
return renderers[0]

## Core arguments
Each serializer field class constructor takes at least these arguments. Some Field classes take additional, field-specific arguments, but the following should always be accepted:
### `source`
The name of the attribute that will be used to populate the field. May be a method that only takes a `self` argument, such as `Field(source='get_absolute_url')`, or may use dotted notation to traverse attributes, such as `Field(source='user.email')`.
The value `source='*'` has a special meaning, and is used to indicate that the entire object should be passed through to the field. This can be useful for creating nested representations. (See the implementation of the `PaginationSerializer` class for an example.)
Defaults to the name of the field.
### `read_only`
Set this to `True` to ensure that the field is used when serializing a representation, but is not used when updating an instance dureing deserialization.
Defaults to `False`
### `required`
Normally an error will be raised if a field is not supplied during deserialization.
Set to false if this field is not required to be present during deserialization.
Defaults to `True`.
### `default`
If set, this gives the default value that will be used for the field if none is supplied. If not set the default behaviour is to not populate the attribute at all.
### `validators`
A list of Django validators that should be used to validate deserialized values.
### `error_messages`
A dictionary of error codes to error messages.
### `widget`
Used only if rendering the field to HTML.
This argument sets the widget that should be used to render the field.

# Filtering
> The root QuerySet provided by the Manager describes all objects in the database table. Usually, though, you'll need to select only a subset of the complete set of objects.
>
> &mdash; [Django documentation][cite]
The default behavior of REST framework's generic list views is to return the entire queryset for a model manager. Often you will want your API to restrict the items that are returned by the queryset.
The simplest way to filter the queryset of any view that subclasses `MultipleObjectAPIView` is to override the `.get_queryset()` method.
Overriding this method allows you to customize the queryset returned by the view in a number of different ways.
## Filtering against the current user
You might want to filter the queryset to ensure that only results relevant to the currently authenticated user making the request are returned.
You can do so by filtering based on the value of `request.user`.
For example:
class PurchaseList(generics.ListAPIView)
model = Purchase
serializer_class = PurchaseSerializer
def get_queryset(self):
"""
This view should return a list of all the purchases
for the currently authenticated user.
"""
user = self.request.user
return Purchase.objects.filter(purchaser=user)
## Filtering against the URL
Another style of filtering might involve restricting the queryset based on some part of the URL.
For example if your URL config contained an entry like this:
url('^purchases/(?P<username>.+)/$', PurchaseList.as_view()),
You could then write a view that returned a purchase queryset filtered by the username portion of the URL:
class PurchaseList(generics.ListAPIView)
model = Purchase
serializer_class = PurchaseSerializer
def get_queryset(self):
"""
This view should return a list of all the purchases for
the user as determined by the username portion of the URL.
"""
username = self.kwargs['username']
return Purchase.objects.filter(purchaser__username=username)
## Filtering against query parameters
A final example of filtering the initial queryset would be to determine the initial queryset based on query parameters in the url.
We can override `.get_queryset()` to deal with URLs such as `http://example.com/api/purchases?username=denvercoder9`, and filter the queryset only if the `username` parameter is included in the URL:
class PurchaseList(generics.ListAPIView)
model = Purchase
serializer_class = PurchaseSerializer
def get_queryset(self):
"""
Optionally restricts the returned purchases to a given user,
by filtering against a `username` query parameter in the URL.
"""
queryset = Purchase.objects.all()
username = self.request.QUERY_PARAMS.get('username', None):
if username is not None:
queryset = queryset.filter(purchaser__username=username)
return queryset

As well as being able to override the default queryset, REST framework also includes support for generic filtering backends that allow you to easily construct complex filters that can be specified by the client using query parameters.
REST framework supports pluggable backends to implement filtering, and provides an implementation which uses the [django-filter] package.
To use REST framework's default filtering backend, first install `django-filter`.
pip install -e git+https://github.com/alex/django-filter.git#egg=django-filter
You must also set the filter backend to `DjangoFilterBackend` in your settings:
REST_FRAMEWORK = {
'FILTER_BACKEND': 'rest_framework.filters.DjangoFilterBackend'
}
**Note**: The currently supported version of `django-filter` is the `master` branch. A PyPI release is expected to be coming soon.
## Specifying filter fields
If all you need is simple equality-based filtering, you can set a `filter_fields` attribute on the view, listing the set of fields you wish to filter against.
class ProductList(generics.ListAPIView):
model = Product
serializer_class = ProductSerializer
filter_fields = ('category', 'in_stock')
This will automatically create a `FilterSet` class for the given fields, and will allow you to make requests such as:
http://example.com/api/products?category=clothing&in_stock=True
## Specifying a FilterSet
For more advanced filtering requirements you can specify a `FilterSet` class that should be used by the view. For example:
class ProductFilter(django_filters.FilterSet):
min_price = django_filters.NumberFilter(lookup_type='gte')
max_price = django_filters.NumberFilter(lookup_type='lte')
class Meta:
model = Product
fields = ['category', 'in_stock', 'min_price', 'max_price']
class ProductList(generics.ListAPIView):
model = Product
serializer_class = ProductSerializer
filter_class = ProductFilter
Which will allow you to make requests such as:
http://example.com/api/products?category=clothing&max_price=10.00
For more details on using filter sets see the [django-filter documentation][django-filter-docs].
---
**Hints & Tips**
* By default filtering is not enabled. If you want to use `DjangoFilterBackend` remember to make sure it is installed by using the `'FILTER_BACKEND'` setting.
* When using boolean fields, you should use the values `True` and `False` in the URL query parameters, rather than `0`, `1`, `true` or `false`. (The allowed boolean values are currently hardwired in Django's [NullBooleanSelect implementation][nullbooleanselect].)
* `django-filter` supports filtering across relationships, using Django's double-underscore syntax.
---
## Overriding the initial queryset
Note that you can use both an overridden `.get_queryset()` and generic filtering together, and everything will work as expected. For example, if `Product` had a many-to-many relationship with `User`, named `purchase`, you might want to write a view like this:
class PurchasedProductsList(generics.ListAPIView):
"""
Return a list of all the products that the authenticated
user has ever purchased, with optional filtering.
"""
model = Product
serializer_class = ProductSerializer
filter_class = ProductFilter
def get_queryset(self):
user = self.request.user
return user.purchase_set.all()
---
# Custom generic filtering
You can also provide your own generic filtering backend, or write an installable app for other developers to use.
To do so override `BaseFilterBackend`, and override the `.filter_queryset(self, request, queryset, view)` method. The method should return a new, filtered queryset.
To install the filter backend, set the `'FILTER_BACKEND'` key in your `'REST_FRAMEWORK'` setting, using the dotted import path of the filter backend class.
For example:
REST_FRAMEWORK = {
'FILTER_BACKEND': 'custom_filters.CustomFilterBackend'
}

[cite]: http://tech.groups.yahoo.com/group/rest-discuss/message/5857 A common pattern for Web APIs is to use filename extensions on URLs to provide an endpoint for a given media type. For example, 'http://example.com/api/users.json' to serve a JSON representation.
Adding format-suffix patterns to each individual entry in the URLconf for your API is error-prone and non-DRY, so REST framework provides a shortcut to adding these patterns to your URLConf.
## format_suffix_patterns
**Signature**: format_suffix_patterns(urlpatterns, suffix_required=False, allowed=None)
Returns a URL pattern list which includes format suffix patterns appended to each of the URL patterns provided.
Arguments:
* **urlpatterns**: Required. A URL pattern list.
* **suffix_required**: Optional. A boolean indicating if suffixes in the URLs should be optional or mandatory. Defaults to `False`, meaning that suffixes are optional by default.
* **allowed**: Optional. A list or tuple of valid format suffixes. If not provided, a wildcard format suffix pattern will be used.
Example:
from rest_framework.urlpatterns import format_suffix_patterns
urlpatterns = patterns('blog.views',
url(r'^/$', 'api_root'),
url(r'^comment/$', 'comment_root'),
url(r'^comment/(?P<pk>[0-9]+)/$', 'comment_instance')
)
urlpatterns = format_suffix_patterns(urlpatterns, allowed=['json', 'html'])
When using `format_suffix_patterns`, you must make sure to add the `'format'` keyword argument to the corresponding views. For example.
@api_view(('GET',))
def api_root(request, format=None):
# do stuff...
The name of the kwarg used may be modified by using the `FORMAT_SUFFIX_KWARG` setting.
Also note that `format_suffix_patterns` does not support descending into `include` URL patterns.
---
## Accept headers vs. format suffixes
There seems to be a view among some of the Web community that filename extensions are not a RESTful pattern, and that `HTTP Accept` headers should always be used instead.
It is actually a misconception. For example, take the following quote from Roy Fielding discussing the relative merits of query parameter media-type indicators vs. file extension media-type indicators:
&ldquo;That's why I always prefer extensions. Neither choice has anything to do with REST.&rdquo; &mdash; Roy Fielding, [REST discuss mailing list][cite2]
The quote does not mention Accept headers, but it does make it clear that format suffixes should be considered an acceptable pattern.

## HTML error views
Typically a renderer will behave the same regardless of if it's dealing with a regular response, or with a response caused by an exception being raised, such as an `Http404` or `PermissionDenied` exception, or a subclass of `APIException`.
If you're using either the `TemplateHTMLRenderer` or the `StaticHTMLRenderer` and an exception is raised, the behavior is slightly different, and mirrors [Django's default handling of error views][django-error-views].
Exceptions raised and handled by an HTML renderer will attempt to render using one of the following methods, by order of precedence.
* Load and render a template named `{status_code}.html`.
* Load and render a template named `api_exception.html`.
* Render the HTTP status code and text, for example "404 Not Found".
Templates will render with a `RequestContext` which includes the `status_code` and `details` keys.

It provides a set of simple decorators that wrap your function based views to ensure they receive an instance of `Request` (rather than the usual Django `HttpRequest`) and allows them to return a `Response` (instead of a Django `HttpResponse`), and allow you to configure how the request is processed.
**[TODO]** ## @api_view()
**Signature:** `@api_view(http_method_names)`
The core of this functionality is the `api_view` decorator, which takes a list of HTTP methods that your view should respond to. For example, this is how you would write a very simple view that just manually returns some data:
from rest_framework.decorators import api_view
@api_view(['GET'])
def hello_world(request):
return Response({"message": "Hello, world!"})
This view will use the default renderers, parsers, authentication classes etc specified in the [settings](settings).
## API policy decorators
To override the default settings, REST framework provides a set of additional decorators which can be added to your views. These must come *after* (below) the `@api_view` decorator. For example, to create a view that uses a [throttle](throttling) to ensure it can only be called once per day by a particular user, use the `@throttle_classes` decorator, passing a list of throttle classes:
from rest_framework.decorators import api_view, throttle_classes
from rest_framework.throttling import UserRateThrottle
class OncePerDayUserThrottle(UserRateThrottle):
rate = '1/day'
@api_view(['GET'])
@throttle_classes([OncePerDayUserThrottle])
def view(request):
return Response({"message": "Hello for today! See you tomorrow!"})
These decorators correspond to the attributes set on `APIView` subclasses, described above.
The available decorators are:
* `@renderer_classes(...)`
* `@parser_classes(...)`
* `@authentication_classes(...)`
* `@throttle_classes(...)`
* `@permission_classes(...)`
Each of these decorators takes a single argument which must be a list or tuple of classes.

If you are considering using REST framework for your API, we recommend reading the [REST framework 2 announcment][rest-framework-2-announcement] which gives a good overview of the framework and it's capabilities.
There is also a sandbox API you can use for testing purposes, [available here][sandbox].

## Browser based PUT, DELETE, etc... ## Browser based PUT, DELETE, etc...
**TODO: Preamble.** Note that this is the same strategy as is used in [Ruby on Rails](2). REST framework supports browser-based `PUT`, `DELETE` and other methods, by
overloading `POST` requests using a hidden form field.
Note that this is the same strategy as is used in [Ruby on Rails][rails].
For example, given the following form: For example, given the following form:
<form action="/news-items/5" method="POST"> <form action="/news-items/5" method="POST">
<input type="hidden" name="_method" value="DELETE"> <input type="hidden" name="_method" value="DELETE">
</form> </form>
`request.method` would return `"DELETE"`. `request.method` would return `"DELETE"`.
## Browser based submission of non-form content ## Browser based submission of non-form content
Browser-based submission of content types other than form are supported by using form fields named `_content` and `_content_type`: Browser-based submission of content types other than form are supported by
using form fields named `_content` and `_content_type`:
For example, given the following form: For example, given the following form:
<form action="/news-items/5" method="PUT"> <form action="/news-items/5" method="PUT">
<input type="hidden" name="_content_type" value="application/json"> <input type="hidden" name="_content_type" value="application/json">
<input name="_content" value="{'count': 1}"> <input name="_content" value="{'count': 1}">
</form> </form>
`request.content_type` would return `"application/json"`, and `request.stream` would return `"{'count': 1}"` `request.content_type` would return `"application/json"`, and
`request.stream` would return `"{'count': 1}"`
## URL based accept headers ## URL based accept headers
REST framework can take `?accept=application/json` style URL parameters,
which allow the `Accept` header to be overridden.
This can be useful for testing the API from a web browser, where you don't
have any control over what is sent in the `Accept` header.
## URL based format suffixes ## URL based format suffixes
REST framework can take `?format=json` style URL parameters, which can be a
useful shortcut for determing which content type should be returned from
the view.
This is a more concise than using the `accept` override, but it also gives
you less control. (For example you can't specify any media type parameters)
## Doesn't HTML5 support PUT and DELETE forms? ## Doesn't HTML5 support PUT and DELETE forms?
Nope. It was at one point intended to support `PUT` and `DELETE` forms, but was later [dropped from the spec](3). There remains [ongoing discussion](4) about adding support for `PUT` and `DELETE`, as well as how to support content types other than form-encoded data. Nope.

# Django REST framework 2
What it is, and why you should care.
> Most people just make the mistake that it should be simple to design simple things. In reality, the effort required to design something is inversely proportional to the simplicity of the result.

**Announcement:** REST framework 2 released - Tue 30th Oct 2012
---
REST framework 2 is an almost complete reworking of the original framework, which comprehensively addresses some of the original design issues.
Because the latest version should be considered a re-release, rather than an incremental improvement, we've skipped a version, and called this release Django REST framework 2.0.
This article is intended to give you a flavor of what REST framework 2 is, and why you might want to give it a try.
## User feedback
Before we get cracking, let's start with the hard sell, with a few bits of feedback from some early adopters…
"Django REST framework 2 is beautiful. Some of the API design is worthy of @kennethreitz." - [Kit La Touche][quote1]
"Since it's pretty much just Django, controlling things like URLs has been a breeze... I think [REST framework 2] has definitely got the right approach here; even simple things like being able to override a function called post to do custom work during rather than having to intimately know what happens during a post make a huge difference to your productivity." - [Ian Strachan][quote2]
"I switched to the 2.0 branch and I don't regret it - fully refactored my code in another &half; day and it's *much* more to my tastes" - [Bruno Desthuilliers][quote3]
Sounds good, right? Let's get into some details...
## Serialization
REST framework 2 includes a totally re-worked serialization engine, that was initially intended as a replacement for Django's existing inflexible fixture serialization, and which meets the following design goals:
* A declarative serialization API, that mirrors Django's `Forms`/`ModelForms` API.
* Structural concerns are decoupled from encoding concerns.
* Able to support rendering and parsing to many formats, including both machine-readable representations and HTML forms.
* Validation that can be mapped to obvious and comprehensive error responses.
* Serializers that support both nested, flat, and partially-nested representations.
* Relationships that can be expressed as primary keys, hyperlinks, slug fields, and other custom representations.
Mapping between the internal state of the system and external representations of that state is the core concern of building Web APIs. Designing serializers that allow the developer to do so in a flexible and obvious way is a deceptively difficult design task, and with the new serialization API we think we've pretty much nailed it.
## Generic views
When REST framework was initially released at the start of 2011, the current Django release was version 1.2. REST framework included a backport of Django 1.3's upcoming `View` class, but it didn't take full advantage of the generic view implementations.
With the new release the generic views in REST framework now tie in with Django's generic views. The end result is that framework is clean, lightweight and easy to use.
## Requests, Responses & Views
REST framework 2 includes `Request` and `Response` classes, than are used in place of Django's existing `HttpRequest` and `HttpResponse` classes. Doing so allows logic such as parsing the incoming request or rendering the outgoing response to be supported transparently by the framework.
The `Request`/`Response` approach leads to a much cleaner API, less logic in the view itself, and a simple, obvious request-response cycle.
REST framework 2 also allows you to work with both function-based and class-based views. For simple API views all you need is a single `@api_view` decorator, and you're good to go.
## API Design
Pretty much every aspect of REST framework has been reworked, with the aim of ironing out some of the design flaws of the previous versions. Each of the components of REST framework are cleanly decoupled, and can be used independantly of each-other, and there are no monolithic resource classes, overcomplicated mixin combinations, or opinionated serialization or URL routing decisions.
## The Browseable API
Django REST framework's most unique feature is the way it is able to serve up both machine-readable representations, and a fully browsable HTML representation to the same endpoints.
Browseable Web APIs are easier to work with, visualize and debug, and generally makes it easier and more frictionless to inspect and work with.
With REST framework 2, the browseable API gets a snazzy new bootstrap-based theme that looks great and is even nicer to work with.
There are also some functionality improvments - actions such as as `POST` and `DELETE` will only display if the user has the appropriate permissions.

**Image above**: An example of the browseable API in REST framework 2
## Documentation
As you can see the documentation for REST framework has been radically improved. It gets a completely new style, using markdown for the documentation source, and a bootstrap-based theme for the styling.
We're really pleased with how the docs style looks - it's simple and clean, is easy to navigate around, and we think it reads great.
## Summary
In short, we've engineered the hell outta this thing, and we're incredibly proud of the result.
If you're interested please take a browse around the documentation. [The tutorial][tut] is a great place to get started.
There's also a [live sandbox version of the tutorial API][sandbox] available for testing.

# Tutorial 4: Authentication & Permissions
Currently our API doesn't have any restrictions on who can edit or delete code snippets. We'd like to have some more advanced behavior in order to make sure that:
* Code snippets are always associated with a creator.
* Only authenticated users may create snippets.
* Only the creator of a snippet may update or delete it.
* Unauthenticated requests should have full read-only access.
## Adding information to our model
We're going to make a couple of changes to our `Snippet` model class.
First, let's add a couple of fields. One of those fields will be used to represent the user who created the code snippet. The other field will be used to store the highlighted HTML representation of the code.
Add the following two fields to the model.
owner = models.ForeignKey('auth.User', related_name='snippets')
highlighted = models.TextField()
We'd also need to make sure that when the model is saved, that we populate the highlighted field, using the `pygments` code higlighting library.
We'll need some extra imports:
from pygments.lexers import get_lexer_by_name
from pygments.formatters import HtmlFormatter
from pygments import highlight
And now we can add a `.save()` method to our model class:
def save(self, *args, **kwargs):
"""
Use the `pygments` library to create an highlighted HTML
representation of the code snippet.
"""
lexer = get_lexer_by_name(self.language)
linenos = self.linenos and 'table' or False
options = self.title and {'title': self.title} or {}
formatter = HtmlFormatter(style=self.style, linenos=linenos,
full=True, **options)
self.highlighted = highlight(self.code, lexer, formatter)
super(Snippet, self).save(*args, **kwargs)
When that's all done we'll need to update our database tables.
Normally we'd create a database migration in order to do that, but for the purposes of this tutorial, let's just delete the database and start again.
rm tmp.db
python ./manage.py syncdb
You might also want to create a few different users, to use for testing the API. The quickest way to do this will be with the `createsuperuser` command.
python ./manage.py createsuperuser
## Adding endpoints for our User models
Now that we've got some users to work with, we'd better add representations of those users to our API. Creating a new serializer is easy:
class UserSerializer(serializers.ModelSerializer):
snippets = serializers.ManyPrimaryKeyRelatedField()
class Meta:
model = User
fields = ('id', 'username', 'snippets')
Because `'snippets'` is a *reverse* relationship on the User model, it will not be included by default when using the `ModelSerializer` class, so we've needed to add an explicit field for it.
We'll also add a couple of views. We'd like to just use read-only views for the user representations, so we'll use the `ListAPIView` and `RetrieveAPIView` generic class based views.
class UserList(generics.ListAPIView):
model = User
serializer_class = UserSerializer
class UserInstance(generics.RetrieveAPIView):
model = User
serializer_class = UserSerializer
Finally we need to add those views into the API, by referencing them from the URL conf.
url(r'^users/$', views.UserList.as_view()),
url(r'^users/(?P<pk>[0-9]+)/$', views.UserInstance.as_view())
## Associating Snippets with Users
Right now, if we created a code snippet, there'd be no way of associating the user that created the snippet, with the snippet instance. The user isn't sent as part of the serialized representation, but is instead a property of the incoming request.
The way we deal with that is by overriding a `.pre_save()` method on our snippet views, that allows us to handle any information that is implicit in the incoming request or requested URL.
On **both** the `SnippetList` and `SnippetDetail` view classes, add the following method:
def pre_save(self, obj):
obj.owner = self.request.user
## Updating our serializer
Now that snippets are associated with the user that created them, let's update our SnippetSerializer to reflect that.
Add the following field to the serializer definition:
owner = serializers.Field(source='owner.username')
**Note**: Make sure you also add `'owner',` to the list of fields in the inner `Meta` class.
This field is doing something quite interesting. The `source` argument controls which attribute is used to populate a field, and can point at any attribute on the serialized instance. It can also take the dotted notation shown above, in which case it will traverse the given attributes, in a similar way as it is used with Django's template language.
The field we've added is the untyped `Field` class, in contrast to the other typed fields, such as `CharField`, `BooleanField` etc... The untyped `Field` is always read-only, and will be used for serialized representations, but will not be used for updating model instances when they are deserialized.
**TODO: Explain the SessionAuthentication and BasicAuthentication classes, and demonstrate using HTTP basic authentication with curl requests**
## Adding required permissions to views
Now that code snippets are associated with users we want to make sure that only authenticated users are able to create, update and delete code snippets.
REST framework includes a number of permission classes that we can use to restrict who can access a given view. In this case the one we're looking for is `IsAuthenticatedOrReadOnly`, which will ensure that authenticated requests get read-write access, and unauthenticated requests get read-only access.
First add the following import in the views module
from rest_framework import permissions
Then, add the following property to **both** the `SnippetList` and `SnippetDetail` view classes.
permission_classes = (permissions.IsAuthenticatedOrReadOnly,)
**TODO: Now that the permissions are restricted, demonstrate using HTTP basic authentication with curl requests**
## Adding login to the Browseable API
If you open a browser and navigate to the browseable API at the moment, you'll find that you're no longer able to create new code snippets. In order to do so we'd need to be able to login as a user.
We can add a login view for use with the browseable API, by editing our URLconf once more.
Add the following import at the top of the file:
from django.conf.urls import include
And, at the end of the file, add a pattern to include the login and logout views for the browseable API.
urlpatterns += patterns('',
url(r'^api-auth/', include('rest_framework.urls',
namespace='rest_framework'))
)
The `r'^api-auth/'` part of pattern can actually be whatever URL you want to use. The only restriction is that the included urls must use the `'rest_framework'` namespace.
Now if you open up the browser again and refresh the page you'll see a 'Login' link in the top right of the page. If you log in as one of the users you created earier, you'll be able to create code snippets again.
Once you've created a few code snippets, navigate to the '/users/' endpoint, and notice that the representation includes a list of the snippet pks that are associated with each user, in each user's 'snippets' field.
## Object level permissions
Really we'd like all code snippets to be visible to anyone, but also make sure that only the user that created a code snippet is able update or delete it.
To do that we're going to need to create a custom permission.
In the snippets app, create a new file, `permissions.py`
from rest_framework import permissions
class IsOwnerOrReadOnly(permissions.BasePermission):
"""
Custom permission to only allow owners of an object to edit it.
"""
def has_permission(self, request, view, obj=None):
# Skip the check unless this is an object-level test
if obj is None:
return True
# Read permissions are allowed to any request
if request.method in permissions.SAFE_METHODS:
return True
# Write permissions are only allowed to the owner of the snippet
return obj.owner == request.user
Now we can add that custom permission to our snippet instance endpoint, by editing the `permission_classes` property on the `SnippetDetail` class:
permission_classes = (permissions.IsAuthenticatedOrReadOnly,
IsOwnerOrReadOnly,)
Make sure to also import the `IsOwnerOrReadOnly` class.
from snippets.permissions import IsOwnerOrReadOnly
Now, if you open a browser again, you find that the 'DELETE' and 'PUT' actions only appear on a snippet instance endpoint if you're logged in as the same user that created the code snippet.
## Summary
We've now got a fairly fine-grained set of permissions on our Web API, and end points for users of the system and for the code snippets that they have created.
In [part 5][tut-5] of the tutorial we'll look at how we can tie everything together by creating an HTML endpoint for our hightlighted snippets, and improve the cohesion of our API by using hyperlinking for the relationships within the system.

# Tutorial 5 - Relationships & Hyperlinked APIs # Tutorial 5 - Relationships & Hyperlinked APIs
**TODO** At the moment relationships within our API are represented by using primary keys. In this part of the tutorial we'll improve the cohesion and discoverability of our API, by instead using hyperlinking for relationships.
* Create BlogPost model ## Creating an endpoint for the root of our API
* Demonstrate nested relationships
* Demonstrate and describe hyperlinked relationships
<!-- Onwards to [part 6][tut-6]. Right now we have endpoints for 'snippets' and 'users', but we don't have a single entry point to our API. To create one, we'll use a regular function-based view and the `@api_view` decorator we introduced earlier.
[tut-6]: 6-resource-orientated-projects.md --> from rest_framework import renderers
from rest_framework.decorators import api_view
from rest_framework.response import Response
from rest_framework.reverse import reverse
@api_view(('GET',))
def api_root(request, format=None):
return Response({
'users': reverse('user-list', request=request),
'snippets': reverse('snippet-list', request=request)
})
Notice that we're using REST framework's `reverse` function in order to return fully-qualified URLs.
## Creating an endpoint for the highlighted snippets
The other obvious thing that's still missing from our pastebin API is the code highlighting endpoints.
Unlike all our other API endpoints, we don't want to use JSON, but instead just present an HTML representation. There are two style of HTML renderer provided by REST framework, one for dealing with HTML rendered using templates, the other for dealing with pre-rendered HTML. The second renderer is the one we'd like to use for this endpoint.
The other thing we need to consider when creating the code highlight view is that there's no existing concrete generic view that we can use. We're not returning an object instance, but instead a property of an object instance.
Instead of using a concrete generic view, we'll use the base class for representing instances, and create our own `.get()` method. In your snippets.views add:
from rest_framework import renderers
from rest_framework.response import Response
class SnippetHighlight(generics.SingleObjectAPIView):
model = Snippet
renderer_classes = (renderers.StaticHTMLRenderer,)
def get(self, request, *args, **kwargs):
snippet = self.get_object()
return Response(snippet.highlighted)
As usual we need to add the new views that we've created in to our URLconf.
We'll add a url pattern for our new API root:
url(r'^$', 'api_root'),
And then add a url pattern for the snippet highlights:
url(r'^snippets/(?P<pk>[0-9]+)/highlight/$', views.SnippetHighlight.as_view()),
## Hyperlinking our API
Dealing with relationships between entities is one of the more challenging aspects of Web API design. There are a number of different ways that we might choose to represent a relationship:
* Using primary keys.
* Using hyperlinking between entities.
* Using a unique identifying slug field on the related entity.
* Using the default string representation of the related entity.
* Nesting the related entity inside the parent representation.
* Some other custom representation.
REST framework supports all of these styles, and can apply them across forward or reverse relationships, or apply them across custom managers such as generic foreign keys.
In this case we'd like to use a hyperlinked style between entities. In order to do so, we'll modify our serializers to extend `HyperlinkedModelSerializer` instead of the existing `ModelSerializer`.
The `HyperlinkedModelSerializer` has the following differences from `ModelSerializer`:
* It does not include the `pk` field by default.
* It includes a `url` field, using `HyperlinkedIdentityField`.
* Relationships use `HyperlinkedRelatedField` and `ManyHyperlinkedRelatedField`,
instead of `PrimaryKeyRelatedField` and `ManyPrimaryKeyRelatedField`.
We can easily re-write our existing serializers to use hyperlinking.
class SnippetSerializer(serializers.HyperlinkedModelSerializer):
owner = serializers.Field(source='owner.username')
highlight = serializers.HyperlinkedIdentityField(view_name='snippet-highlight', format='html')
class Meta:
model = models.Snippet
fields = ('url', 'highlight', 'owner',
'title', 'code', 'linenos', 'language', 'style')
class UserSerializer(serializers.HyperlinkedModelSerializer):
snippets = serializers.ManyHyperlinkedRelatedField(view_name='snippet-detail')
class Meta:
model = User
fields = ('url', 'username', 'snippets')
Notice that we've also added a new `'highlight'` field. This field is of the same type as the `url` field, except that it points to the `'snippet-highlight'` url pattern, instead of the `'snippet-detail'` url pattern.
Because we've included format suffixed URLs such as `'.json'`, we also need to indicate on the `highlight` field that any format suffixed hyperlinks it returns should use the `'.html'` suffix.
## Making sure our URL patterns are named
If we're going to have a hyperlinked API, we need to make sure we name our URL patterns. Let's take a look at which URL patterns we need to name.
* The root of our API refers to `'user-list'` and `'snippet-list'`.
* Our snippet serializer includes a field that refers to `'snippet-highlight'`.
* Our user serializer includes a field that refers to `'snippet-detail'`.
* Our snippet and user serializers include `'url'` fields that by default will refer to `'{model_name}-detail'`, which in this case will be `'snippet-detail'` and `'user-detail'`.
After adding all those names into our URLconf, our final `'urls.py'` file should look something like this:
# API endpoints
urlpatterns = format_suffix_patterns(patterns('snippets.views',
url(r'^$', 'api_root'),
url(r'^snippets/$',
views.SnippetList.as_view(),
name='snippet-list'),
url(r'^snippets/(?P<pk>[0-9]+)/$',
views.SnippetDetail.as_view(),
name='snippet-detail'),
url(r'^snippets/(?P<pk>[0-9]+)/highlight/$'
views.SnippetHighlight.as_view(),
name='snippet-highlight'),
url(r'^users/$',
views.UserList.as_view(),
name='user-list'),
url(r'^users/(?P<pk>[0-9]+)/$',
views.UserInstance.as_view(),
name='user-detail')
))
# Login and logout views for the browsable API
urlpatterns += patterns('',
url(r'^api-auth/', include('rest_framework.urls',
namespace='rest_framework'))
)
## Adding pagination
The list views for users and code snippets could end up returning quite a lot of instances, so really we'd like to make sure we paginate the results, and allow the API client to step through each of the individual pages.
We can change the default list style to use pagination, by modifying our `settings.py` file slightly. Add the following setting:
REST_FRAMEWORK = {
'PAGINATE_BY': 10
}
Note that settings in REST framework are all namespaced into a single dictionary setting, named 'REST_FRAMEWORK', which helps keep them well seperated from your other project settings.
We could also customize the pagination style if we needed too, but in this case we'll just stick with the default.
## Reviewing our work
If we open a browser and navigate to the browseable API, you'll find that you can now work your way around the API simply by following links.
You'll also be able to see the 'highlight' links on the snippet instances, that will take you to the hightlighted code HTML representations.
We've now got a complete pastebin Web API, which is fully web browseable, and comes complete with authentication, per-object permissions, and multiple renderer formats.
We've walked through each step of the design process, and seen how if we need to customize anything we can gradually work our way down to simply using regular Django views.
You can review the final [tutorial code][repo] on GitHub, or try out a live example in [the sandbox][sandbox].

# Tutorial 6 - Resources
Resource classes are just View classes that don't have any handler methods bound to them. The actions on a resource are defined,
This allows us to:
* Encapsulate common behaviour across a class of views, in a single Resource class.
* Separate out the actions of a Resource from the specfics of how those actions should be bound to a particular set of URLs.
## Refactoring to use Resources, not Views
For instance, we can re-write our 4 sets of views into something more compact...
resources.py
class BlogPostResource(ModelResource):
serializer_class = BlogPostSerializer
model = BlogPost
permissions_classes = (permissions.IsAuthenticatedOrReadOnly,)
throttle_classes = (throttles.UserRateThrottle,)
class CommentResource(ModelResource):
serializer_class = CommentSerializer
model = Comment
permissions_classes = (permissions.IsAuthenticatedOrReadOnly,)
throttle_classes = (throttles.UserRateThrottle,)
## Binding Resources to URLs explicitly
The handler methods only get bound to the actions when we define the URLConf. Here's our urls.py:
comment_root = CommentResource.as_view(actions={
'get': 'list',
'post': 'create'
})
comment_instance = CommentInstance.as_view(actions={
'get': 'retrieve',
'put': 'update',
'delete': 'destroy'
})
... # And for blog post
urlpatterns = patterns('blogpost.views',
url(r'^$', comment_root),
url(r'^(?P<pk>[0-9]+)$', comment_instance)
... # And for blog post
)
## Using Routers
Right now that hasn't really saved us a lot of code. However, now that we're using Resources rather than Views, we actually don't need to design the urlconf ourselves. The conventions for wiring up resources into views and urls can be handled automatically, using `Router` classes. All we need to do is register the appropriate resources with a router, and let it do the rest. Here's our re-wired `urls.py` file.
from blog import resources
from rest_framework.routers import DefaultRouter
router = DefaultRouter()
router.register(resources.BlogPostResource)
router.register(resources.CommentResource)
urlpatterns = router.urlpatterns
## Trade-offs between views vs resources.
Writing resource-oriented code can be a good thing. It helps ensure that URL conventions will be consistent across your APIs, and minimises the amount of code you need to write.
The trade-off is that the behaviour is less explict. It can be more difficult to determine what code path is being followed, or where to override some behaviour.
