Adding a extra field to user (create user including that field)
I want to use an extra field let me distinguish between user roles. For that, I've overriden the User class: class User(AbstractUser): role = models.CharField(max_length=21, blank=False) I've also put this in settings.py: AUTH_USER_MODEL = 'shopping.User' The problem is that I have the new field in my database, but, if I want to create a new user using the admin, it doesn't ask me for the role. I suppose that I have to override the save method too, but I don't know how. Thanks in advance -

Django - storing session object in settings.py
I have an api(legacy), a front end app(legacy) , and a django app(in development). Both the legacy front end app is fully working with the legacy api that operates with a mysql database. I have integrated my django app with that database and for some features I am using some endpoints from the legacy api. In order to do that I must login by sending credentials to that api - I am doing this using python sessions in order to store the cookie. Question Is it safe to instantiate the session object in the settings.py? from requests import Session session = Session() Is there a better way to communicate with the legacy api? Maybe using django sessions as cookie, I have tried many ways to make it work and it works now. If I am using a cookie with JSESSIONID=random string then api does not accept that as a cookie. That's why I am using python sessions. -

How can I rebuild search index of Elasticsearch in Django automatically on docker startup?
It's my first time using Elasticsearch with Django on Docker and I realize that every time I start docker-compose, I have to issue ./manage.py search_index --rebuild to index all my documents in Elasticsearch. I've been trying to do this automatically but still doesn't seem to work. My web service command looks like this: web: build: . command: bash -c "python manage.py runserver 0.0.0.0:8000 && sleep 60 && python manage.py search_index --rebuild" ... I added sleep 60 so that it can wait for Elasticsearch to start up before issuing the rebuild command. And even with that, nothing happens unless I explicitly issue it manually. -

How to limit the number of items of a ForeignKey field when I'm fetching an object in Django GraphQL API using Graphene?
I have a simple chat application with a GraphQL API written in Django with Graphene plugin. And an Angular UI with Apollo as the GraphQL client. I have a chat model that is like chat rooms and a chatMessage model that is more of the individual message that is tied to the chat model via a foreignKey field, so that every chat message is tied to some chat item.
