django-allauth: how to properly use email_confirmed signal to set user to active

问题

In another post, I mentioned that I was trying to use allauth's email_confirmed signal to change the is_active field on the confirmed user to true. However, the following code gave me the exception "User matching query does not exist."

from allauth.account.signals import email_confirmed
from django.dispatch import receiver
from django.contrib.auth.models import User

@receiver(email_confirmed)
def email_confirmed_(request, email_address, **kwargs):

    user = User.objects.get(email=email_address)
    user.is_active = True

    user.save()

I tried to re-work this, and still got a similar exception, "EmailAddress matching query does not exist."

from allauth.account.signals import email_confirmed
from django.dispatch import receiver
from django.contrib.auth.models import User
from allauth.account.models import EmailAddress

@receiver(email_confirmed)
def email_confirmed_(request, email_address, **kwargs):

    new_email_address = EmailAddress.objects.get(email=email_address)
    user = User.objects.get(new_email_address.user)
    user.is_active = True

    user.save()

Traceback is here:

Exception Value: EmailAddress matching query does not exist.

This is confusing to me, because I can check the email address field in both the user table and the "email addresses" table in my database and they both seem to have matching email addresses. Help would be appreciated!

Turns out the email_address returned by the email_confirmed signal isn't actually a string containing the address, but an object -- allauth.account.models.EmailAddress. This wasn't very clear at all from the documentation, but glad it's resolved now. The code that ended up working was:

@receiver(email_confirmed)
def email_confirmed_(request, email_address, **kwargs):

    user = User.objects.get(email=email_address.email)
    user.is_active = True

    user.save()

I found this page while trying to set up a signal from AllAuth to my CustomUser Model.

After some debugging and continued searching, I found an old GitHub thread on the subject: https://github.com/pennersr/django-allauth/issues/347. His solution worked for me.

I changed the location of my receiver function from app/signals.py to app/models.py

Apparently, by default the ready() function of the AppConfig Class imports the models.py file, but a signals.py file needs to be manually added to your apps.py file:

from django.apps import AppConfig


class NameOfAppConfig(AppConfig):
    name = 'NameOfApp'

    def ready(self):
        import NameOfApp.signals

Anyway, it's easy to miss this in the documentation. I'd guess in future Django releases they will include a signals.py file as a default file and incorporate it automatically.
