更新 我尝试用以下内容替换自定义管理器中的所有内容：
def create_user(self, username, email):
return self.model._default_manager.create(username=username)
这会引发错误。然后我尝试从我的自定义用户管理器返回用户，我得到“无法分配”：“UserSocialAuth.user”必须是“Barbuser”实例。从 associate_user 抛出。它来自 django.db.models.fields.related.py 的内部。基本上，我坚持知道如何从我的自定义模型经理中正确创建用户。我直接离开了导致我从 django 内置的 ModelManager 中复制所有内容的文档。帮助？ 更新
我在配置 django-social-auth 时遇到问题。我已经在这里待了 3-4 天，我正准备认输。我安装了一个可用的现有用户注册应用程序，然后我安装并遵循了 django-social-auth github 站点上的文档。我将以下内容添加到我的 settings.py

我的 models.py 看起来像：

我已经更新了我的 urls.py 以包含“social_auth.urls”，并且在身份验证后，用户从我的 views.py 被重定向到 ViewProfile 视图：

我的问题是 2 倍。当我在我的 models.py 中添加这些额外的东西时：
def facebook_extra_values(sender, user, response, details, **kwargs):
return False
from social_auth.signals import pre_update
from social_auth.backends.facebook import FacebookBackend
pre_update.connect(facebook_extra_values, sender=FacebookBackend)
我在服务器启动时遇到错误：assert isinstance(to, basestring), "%s(%r) is invalid. ForeignKey 的第一个参数必须是模型、模型名称或字符串 %r" % ( self.class ._ name _, to, RECURSIVE_RELATIONSHIP_CONSTANT) AssertionError: ForeignKey(None) 无效。ForeignKey 的第一个参数必须是模型、模型名称或字符串“self”
当我删除它时，我可以通过 facebook 流程登录，但我得到：/complete/facebook/ 'NoneType' 对象的 AttributeError 没有属性 'extra_data'
我不确定我错过了什么或哪里出错了。有人可以帮助解释我哪里出错了吗？
更新 我已经在调试中跟踪了这个问题，显然当它尝试“UserSocialAuth.objects.create”时，我在 associate_user 函数中的 social_auth.backends.pipeline.social.py 中得到了一个 IntegrityError。然后它回退到调用 social_auth_user() 的 except 块中，并且此函数为 social_user 返回 None。我得到的 IntegrityError 是：
insert or update on table "social_auth_usersocialauth" violates foreign key constraint "social_auth_usersocialauth_user_id_fkey"
DETAIL: Key (user_id)=(17) is not present in table "auth_user".
我不够熟悉，不知道如何、在哪里或为什么将 social_user 与在我的 models.py 中的 CustomUserManager 中创建的用户相关联。此外，我还删除了 models.py 底部的 facebook_extra_values、额外导入和 preupdate.connect 内容，因为我真的不明白它的作用或用途。我只是从示例应用程序中复制东西，试图解决我的第一个问题，即缺少关联。帮助？ 更新
