Make sure that you have mongodb running. You can simply open a new terminal tab and type:
mongod
## Installing elasticsearch
brew install elasticsearch
For debugging, it's often more convenient to have elasticsearch running in a terminal tab instead of in background. To do so, simply open a new terminal tab and then type:
elasticsearch -f
## Setting up the discussion service
First, make sure that you have access to the [github repository](https://github.com/rll/cs_comments_service). If this were not the case, send an email to dementrock@gmail.com.
If you see a prompt asking "Do you wish to trust this .rvmrc file?", type "y"
Now if you see this error "Gemset 'cs_comments_service' does not exist," run the following command to create the gemset and then use the rvm environment manually:
rvm gemset create 'cs_comments_service'
rvm use 1.9.3@cs_comments_service
Now use the following command to install required packages:
bundle install
The following command creates database indexes:
bundle exec rake db:init
Now use the following command to generate seeds (basically some random comments in Latin):
bundle exec rake db:seed
It's done! Launch the app now:
ruby app.rb
## Running the delayed job worker
In the discussion service, notifications are handled asynchronously using a third party gem called delayed_job. If you want to test this functionality, run the following command in a separate tab:
bundle exec rake jobs:work
## Some other useful commands
### generate seeds for a specific forum
The seed generating command above assumes that you have the following discussion tags somewhere in the course data:
<section format="Lab" name="Lab0: Using the tools">
<vertical>
<html> See the <a href="/section/labintro"> Lab Introduction </a> or <a href="/static/handouts/schematic_tutorial.pdf">Interactive Lab Usage Handout </a> for information on how to do the lab </html>
<problem name="Lab 0: Using the Tools" filename="Lab0" rerandomize="false"/>
<discussion for="Lab 0: Using the Tools" id="lab_1" discussion_category="Lab"/>
Currently, only the attribute "id" is actually used, which is the unique identification of the discussion forum. In the data generator code, the lines for generating seeds are as following:
generate_comments_for("video_1")
generate_comments_for("lab_1")
generate_comments_for("lab_2")
We also have a command for generating comments within a forum with the specified id:
For instance, if you want to generate comments for the general discussion, for which the discussion id is the course id with slashes and dots replaced by underscores (you *should* do this before testing forum view) and you are in 6.002x, use the following command
