python - 更新指向 settings.AUTH_USER_MODEL 的关系

Question

我遇到了这个错误。我正在尝试配置 tschellenbach/Django-facebook 包。我收到“用户或配置文件没有属性 facebook_id”错误。所以我尝试使用 facebook_example 中的代码对其进行配置这是随包提供的一个工作示例。我应该怎么做才能对它进行排序？请帮忙

course.course: 'author' defines a relation with the model 'auth.User',
which has been swapped out. Update the relation to point at 
settings.AUTH_USER_MODEL.

问题是现在你有一个 CUSTOM USER 并且你正在对 Django User Model 做一个 ForeingKey ( author = models.ForeignKey(User, related_name="类(class)") ) 获取新的 User 你可以在你将使用 User

的任何文件的开头执行此操作

from django.contrib.auth import get_user_model as user_model
User = user_model()
