Django-Social-Auth错误(Django-Social-Auth Errors)

 更新我尝试使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的内容。 基本上，我知道如何从我的自定义模型mgr正确创建用户。 我直接从文档引导我复制django内置的ModelManager中的所有内容。 帮帮我？ 更新 
 
 我在配置django-social-auth时遇到了问题。 我已经待了3-4天了，我已经准备好了。 我安装了一个现有的用户注册应用程序，然后我安装并跟随django-social-auth github网站上的文档。 我在settings.py中添加了以下内容

 我的问题是2倍。 当我在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）无效.OignanKey的第一个参数必须是模型，模型名称或字符串％r”％（self。 类 ._ 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：/ Error / at / facebook /'NoneType'对象没有属性'extra_data' 
 
 我不确定我错过了什么或我哪里出错了。 有人可以帮我解释我哪里错了吗？ 
 
 更新我在调试中跟踪了问题，显然我在associate_user函数中的social_auth.backends.pipeline.social.py中遇到IntegrityError，当它尝试“UserSocialAuth.objects.create”时。 然后它回退到一个调用social_auth_user（）的Except块，这个函数为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".
 
 我不熟悉知道如何，在何处或为何将social_user与我在models.py中的CustomUserManager中创建的用户相关联。 此外，我从models.py的底部删除了facebook_extra_values，额外的导入和preupdate.connect，因为我真的不明白它的作用或它的用途。 我只是从示例应用程序复制的东西试图修复我的第一个问题与缺少的关联。 帮帮我？ 更新 

Update I tried replacing everything in my custom manager with the following:
 
def create_user(self, username, email):
        return self.model._default_manager.create(username=username)
 
And that throws an error. I then tried returning the User from my custom user manager and I get 'Cannot assign "": "UserSocialAuth.user" must be a "Barbuser" instance.' thrown from associate_user. It comes from the bowels of django.db.models.fields.related.py. Basically, I'm stuck with knowing how to correctly create users from my custom model mgr. I was going directly off of the docs which lead me to copying everything from django's built in ModelManager. Help? Update
 
I'm having trouble configuring django-social-auth. I've been at this for 3-4 days and I'm getting ready to throw in the towel. I have a working existing user registration app installed and I then installed and followed along with the docs on django-social-auth github site. I added the following to my settings.py

pre_update.connect(facebook_extra_values, sender=FacebookBackend)
 
I get errors on server startup: assert isinstance(to, basestring), "%s(%r) is invalid. First parameter to ForeignKey must be either a model, a model name, or the string %r" % (self.class._name_, to, RECURSIVE_RELATIONSHIP_CONSTANT) AssertionError: ForeignKey(None) is invalid. First parameter to ForeignKey must be either a model, a model name, or the string 'self'
 
When I remove it I can go thru the login with facebook flow but I get: AttributeError at /complete/facebook/ 'NoneType' object has no attribute 'extra_data'
 
I'm not sure what I'm missing or where I've gone wrong. could somebody help explain where I'm going wrong?
 
Update I've traced the problem in debug and apparently I'm getting an IntegrityError in social_auth.backends.pipeline.social.py in the associate_user function when it tries "UserSocialAuth.objects.create". It then falls back into an Except block that calls social_auth_user() and this function returns None for the social_user. The IntegrityError I'm getting is: 
 
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".
 
I'm not familiar enough to know how, where or why to associate a social_user with the user created in my CustomUserManager in my models.py. Also I've removed the facebook_extra_values, extra imports, and the preupdate.connect stuff from the bottom of my models.py since I really don't understand what it does or what it's for. I was merely copying things from the example app trying to fix my first problem with the missing association. Help? Update
