Chapter 6 -- "User" is not defined

[JordanBarnartt]

Chapter 6 adds validation to ensure that email addresses are not reused when a user is registering or editing their profile.

However, the User object at

Django-5-By-Example/Chapter06/bookmarks/account/forms.py

Line 34 in a4c1e4e

if User.objects.filter(email=data).exists():

and

Django-5-By-Example/Chapter06/bookmarks/account/forms.py

Line 46 in a4c1e4e

qs = User.objects.exclude(

is not actually defined anywhere.

Comparing to https://github.com/PacktPublishing/Django-4-by-example/blob/main/Chapter05/bookmarks/account/forms.py, it looks like the import of User was replaced with get_user_model without fixing these two instances.

Doing something like the following solves the issue:

def clean_email(self):
        data = self.cleaned_data["email"]
        user = get_user_model()
        if user.objects.filter(email=data).exists():
            raise forms.ValidationError("Email already in use.")
        return data

...

def clean_email(self):
        data = self.cleaned_data["email"]
        user = get_user_model()
        qs = user.objects.exclude(id=self.instance.id).filter(email=data)
        if qs.exists():
            raise forms.ValidationError("Email already in use.")
        return data
