Django反向访问器冲突

Question

所以在这里我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用于任何一个提供程序......但是我在整个地方都遇到了冲突错误.

介意看看我的代码并查看是否有任何方法可以让我这样做,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(以及同样的provider.profile,而无需知道哪种类型的供应商)？或者只是告诉我,我正在尝试做的事情是不可能的,还有更好的解决方案？

Answer 1

related_name必须是独一无二的.你给的所有人都给了同样的名字related_name.

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')
