To run the redis server, type docker run -d --name redis-stack -p 6379:6379 redis/redis-stack:latest

In the repo folder, type pipenv shell. This will lead you to the venv of the project.

Then, type python manage.py runserver when you're in the repo root folder.

Now, you can go into http://localhost:8000/redis to access the project.

Once a user is registered to a course, he's automatically subscribed to courses update for all courses he follows into the notifications page.

### Sessions

This app works with sessions. You have to play with this project with 2 browsers to test the pub/sub.

To test pub/sub, please follow these instructions:

Open a browser, register as a Teacher, create a course.

Open another browser, register as a Student, search your course, register to it, and go to notifications.

As the teacher, update, delete or publish a message from the course created.

As a student, you'll see instantly the message.

You can also do this with redis-cli. To do that, in a shell, type:

docker start redis-stack
docker exec -it redis-stack bash
redis-cli
psubscribe {id} where the id is the course id where you will post messages from (with an update of the course or with Publish message). you can retrieve it with KEYS course:*
Update the course or post the message from this course id

docker start redis-stack
docker exec -it redis-stack bash
redis-cli
Go to your notifications after registered to a course (if you didn't you will get redirected to the courses page, where you can see that you don't follow any course)
publish {id} {message} where id is one of the course id followed by the current user, and message is your message

Expiration of the course: The course expires after 2 minutes.
