Question

使用Django 1.10我使用自定义后端登录时没有问题（不是自定义用户只是auth），但在1.11rc1我收到以下异常：

Request Method:     POST
Request URL:    http://127.0.0.1:8000/admin/login/?next=/admin/
Django Version:     1.11rc1
Exception Type:     FieldError
Exception Value:    

Cannot resolve keyword 'request' into field. Choices are: clientcontact, crudevent, date_joined, email, <...just more fields>

后端：

    def authenticate(self, **kwargs):
        if kwargs:
            username = kwargs.pop("username", None)
            if username:
                username_or_email = Q(username=username) | Q(email=username)
                password = kwargs.pop("password", None)
                try:
                    user = User.objects.get(username_or_email, **kwargs)
                except User.DoesNotExist:
                    pass
                else:
                    if user.check_password(password):
                        return user
        else:
            ...

在settings.py：

AUTHENTICATION_BACKENDS = ('base_app.auth_backend.JbcBackend', 'guardian.backends.ObjectPermissionBackend',)

如果有人能指出我正确的方向，那我就找不到任何东西了。这是完整的追溯：

Answer 1

try:
    user = User.objects.get(username_or_email)
    # The user is found, now check if the password matches
    if user.check_password(password):
        return user
except User.DoesNotExist:
    pass
...

无法在Django 1.11.rc1
