A strange error appears in Django 2.2 (it's was working in the previous
version) when I write a process to authenticate user with email.
{{{
class LoginForm(forms.Form):
login = forms.CharField()
password = forms.CharField()
def clean(self):
user = User.objects.filter(
Q(username__iexact=self.cleaned_data["login"]) |
Q(email__iexact=self.cleaned_data["login"])
).first()
if user:
if authenticate(username=user.username,
password=self.cleaned_data["password"]) is not None:
return self.cleaned_data
else:
self.add_error('login', "This user is inactive.")
else:
self.add_error('login', "This user does not exist.")
return self.cleaned_data
}}}
The authentication system work when username is given and correct error is
returned when email exist but the password is wrong. But when the
credentials are valid, an error is raised in form by Django.
The little work around I found is to replace the mail submitted in the
form by the username collect by the query before return the cleaned data:
{{{
if authenticate(username=user.username,
password=self.cleaned_data["password"]) is not None:
self.cleaned_data['login'] = user.username
return self.cleaned_data
}}}
I'm pretty sur Django doesn't have this error in 2.1 when I write this
code, I had validated that it was working.
Sincerely.
