django-allauth：自定义用户在/accounts/signup/处生成IntegrityError（自定义字段被置空或丢失）

Question

我正在尝试将django-allauth与自定义用户模型（子类化AbstractUser）集成，但是当我测试注册表单时，由于字段（date_of_birth）为空，但提交的值为u'1976-4-6'，所以我遇到了完整性错误。

我正在学习新的自定义用户内容，以及类视图，因为我正在学习django-allauth，所以我有信心我在做错了什么，但是经过几天读取github问题、少量教程、readthedocs和stackoverflow问题后，我仍然不清楚我做错了什么（好吧，我知道我做错了一件事：这里和那里尝试不同的解决方案，所以我肯定有一个杂乱无章的实现）。

但是，我找不到一个好的答案来将allauth与子类化的AbstractUser集成，如果有人能启示我，我会非常感激。

（注-当我作为已通过修补程序加载的用户登录时，该网站或多或少工作正常，因此请假设非django-allauth省略是省略-如果您需要澄清以下内容，请告诉我。）

Answer 1

答案——我仍在摸索中——似乎是，如果您正在保存一个包含字段类型的模型，而这些字段类型allauth.account.adapter.DefaultAccountAdapter不能正确处理（例如，任何缺少__getitem__属性的字段，比如models.DateField），则需要实现一个自定义适配器，如下所示。

注意：您子类化的抽象用户模型是传递的用户，因此最佳实践是直接使用表单数据，例如 user.email = data.get('email')，而不是使用DefaultAccountAdapter类中使用的allauth内部方法。

userdata/adapter.py

class AccountAdapter(DefaultAccountAdapter):
    def save_user(self, request, user, form, commit=False):
        data = form.cleaned_data
        user.email = data.get('email')
        user.username = data.get('username')
        # all your custom fields
        user.date_of_birth = data.get('date_of_birth')
        user.gender = data.get('gender')
        if 'password1' in data:
            user.set_password(data["password1"])
        else:
            user.set_unusable_password()
        self.populate_username(request, user)
        if commit:
            user.save()
        return user
