django-allauth - kundenspezifische Adapter gibt Fehler: UNIQUE-Einschränkung fehlgeschlagen: main_user.email

Question

Meine benutzerdefinierte adapters.py Datei enthält diese (und ich habe richtig es in settings.py verbunden, natürlich):

from allauth.account.adapter import DefaultAccountAdapter 


class AccountAdapter(DefaultAccountAdapter): 
    def save_user(self, request, user, form, commit=True): 
     data = form.cleaned_data 
     user.username = data.get('username') 
     user.email = data.get('email') 
     user.first_name = data.get('first_name') 
     user.last_name = data.get('last_name') 
     user.gender = data.get('gender') 
     user.birth_date = data.get('birth_date') 
     user.city = data.get('city') 
     user.country = data.get('country') 
     if 'password1' in data: 
      user.set_password(data.get('password1')) 
     else: 
      user.set_unusable_password() 
     self.populate_username(request, user) 
     if commit: 
      user.save() 
     return user 

Der Fehler passiert irgendwo im Code in Allauth, und ich kann nicht herausfinden, warum. Ich habe das selbe wie in der ursprünglichen Adapterspeichermethode gemacht, aber aus irgendeinem Grund funktioniert es nicht für mein kundenspezifisches.

Hier ist ein voller Stack-Trace, wenn jemand, der sehen will, auch:

Answer 1

ich es behoben habe, war das Problem mit meinem Anmeldeformular (in forms.py). Es sieht jetzt so aus:

from django.contrib.auth.forms import UserCreationForm 
from django import forms 
from django.forms import extras 
from django.contrib.auth import get_user_model 

BIRTH_DATE_YEARS = ('2015','2014','2013','2012','2011','2010','2009','2008','2007','2006','2005','2004','2003','2002', 
        '2001','2000','1999','1998','1997','1996','1995','1994','1993','1992','1991','1990','1989','1988', 
        '1987','1986','1985','1984','1983','1982','1981','1980','1979','1978','1977','1976','1975','1974', 
        '1973','1972','1971','1970','1969','1968','1967','1966','1965','1964','1963','1962','1961','1960', 
        '1959','1958','1957','1956','1955','1954','1953','1952','1951','1950','1949','1948','1947','1946', 
        '1945','1944','1943','1942','1941','1940','1939','1938','1937','1936','1935','1934','1933','1932', 
        '1931','1930','1929','1928','1927') 


class RegistrationForm(UserCreationForm): 
    birth_date = forms.DateField(widget=extras.SelectDateWidget(years=BIRTH_DATE_YEARS)) 

    class Meta: 
     model = get_user_model() 
     fields = ('username', 'email', 'password1', 'password2', 'first_name', 'last_name', 'gender', 'birth_date', 'city', 'country') 

    def signup(self, request, user): 
     pass
