We want to allow the admin to choose wether the users can signin in by
themselves, or if only the admin can do it. We will later implement it
in the python code
Here we have to modify
- docker-compose.yml : add the env ALLOW_SIGNUP
Note: I am not sure if it's True or "True"
Note: we could have put it inside the Dockerfile instead of
docker-compose, it doesn't matter.
- settings.py : Here we make the env variable available to the python
app
- app.json : that's for the heroku deployment. we simply describe to
heroku that we have an env variable
