所以我在这里遇到了很多反向访问冲突的问题。我虽然我非常聪明并且干我的模型结构能够将user.profile用于任何类型的配置文件，或者将provider.profile用于任何一个提供商......但我在整个过程中都遇到了冲突错误这个地方。
介意看看我的代码并查看是否有任何方法让我这样做，这样我仍然可以只使用user.profile而无需知道哪种类型的配置文件（同样也不需要知道provider.profile）哪种提供者）？或者只是告诉我，我尝试做的事情是不可能的，还有更好的解决方案吗？

答案 0 :(得分：48)
related_name必须是唯一的。你给所有related_name提供了相同的名称。
尝试将它们重命名为：
user = models.OneToOneField(User, related_name="custom_user_profile", primary_key=True)
#..
provider = models.OneToOneField(Provider, related_name='user_ind_provider_profile')
#..
provider = models.OneToOneField(Provider, related_name='user_org_provider_profile')
