ジャンゴ - allauth - カスタムアダプタを使用すると、エラーを与える：UNIQUE制約に失敗しました：main_user.email

Question

マイカスタムadapters.pyファイルには、これを含まれています（と私は正しくsettings.pyでそれにリンクした、もちろん）：

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 

エラーはallauthのコードのどこかで発生します。理由を把握できません。私は元のアダプタの保存方法のように同じでしたが、何らかの理由でそれは私のカスタム1のために動作しません。誰かがそれを見たい場合

ここで完全なスタックトレースがあまりにも、です：私はそれを修正しました

、問題は（forms.pyで）私のサインアップフォームしていました。これは次のようになります：

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',

        '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
