Emit a user_logged_in signal much like in django.contrib.auth

[hetsch]

I have the situation where I have to post-process a valid login and enriching the User object with some custom data. In the backend, I listen for the user_logged_in signal of the django.contrib.auth framework. This works great so far, but if a user logs via the frontend (REST and django-oauth-tookit), the user_logged_in signal is not emitted. My question would be if you think it would be worthwhile or even possible to implement the user_logged_in signal dispatching logic in this great package? Thank's for your thoughts and help!

Hello hetch, we shouldn't use login function i.e.., from django.contrib.auth, because in REST we use different authentication methods like token or basic authentication techniques right. i think it's better to send signal explicitly when ever you try to generate token or authenticate with the credentials. Still we can make that happen for triggering signal user ### login function and the remove those user credentials from the sessions table that's it

Based on this Stackoverflow post, I used the following to solve this issue:

from django.contrib.auth.signals import user_logged_in

from oauth2_provider.signals import app_authorized
from oauth2_provider.models import AccessToken

def handle_app_authorized(sender, request, token, **kwargs):
    if not AccessToken.objects.filter(token=token).exists():
        return

    access_token = AccessToken.objects.get(token=token)

    if access_token.user:
        user_logged_in.send(sender=sender, request=request,
                            user=access_token.user)

app_authorized.connect(handle_app_authorized)

I was then able to use @receiver(user_logged_in) to receive the log in signal from django-oauth-toolkit.
