我的自定义adapters.py文件包含此内容（当然，我已正确地在settings.py中链接到它）：
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
错误发生在allauth代码的某处，我无法弄清楚原因。我在原始适配器保存方法中也做了同样的事情，但由于某些原因它不能用于我的自定义保存方法。
如果有人想要看到它，那么这里是一个完整的堆栈跟踪：

答案 0 :(得分：0)
我已修复它，问题在于我的注册表单（在forms.py中）。它现在看起来像这样：
from django.contrib.auth.forms import UserCreationForm
from django import forms
from django.forms import extras
from django.contrib.auth import get_user_model
