python - Signal configured but it still retruns UserProfile matching query does not exist -

the following form returns userprofile matching query not exist. though configured signal.

and works expected inetrpreter.

in [1]: core.models import user  in [2]: u = user.objects.get(id = 1)  in [3]: user_address = u.get_profile().home_address  in [4]: user_address = '20 st.'

like cberner said, think it's because:

i believe you're getting error because call super(registerform, self).save(commit=false). if use commit=false django wouldn't emit post_save signal, since model isn't committed database.

here's solution:

def save(self, commit=true):     user = super(registerform, self).save(commit=false)     user.email      = self.cleaned_data['email']     user.first_name = self.cleaned_data['first_name']     user.last_name  = self.cleaned_data['last_name']     user.permission = self.cleaned_data['permission']     user.save()      user_profile    = userprofile(user=user, url=self.cleaned_data['url'])     if commit:         user_profile.save()     return user
