Exception Type: IntegrityError at /accounts/signup/
Exception Value: FOREIGN KEY constraint failed
我正在使用 allauth 并覆盖注册表单以在表单中包含手机号码字段，但一旦我点击注册按钮，我就会收到以下错误。我有一个想法，这可能是因为令牌，因为它不是在用户注册后自动创建的。
class SignupForm(forms.ModelForm):
mobile_number = forms.CharField(max_length=11)
class Meta:
model = User
fields = ['mobile_number']
def signup(self, request, user):
print("User is",user)
user.mobile_number = self.cleaned_data['mobile_number']
user.save()
return user
我的最终目标是使用手机号码字段作为前端和 API 调用中的登录名。

我删除了我的sqlite数据库，然后运行"python manage.py 迁移"它起作用了。如果您有不想删除的数据，只需重命名旧数据库即可。
