无法访问 Django 模板中的 UserProfile 模型字段。试过 {{ user.userprofile }}

Question

我尝试导入 {{ user.userprofile. }} 和 {{ user.userprofile }} 没有成功。在 django shell 中，我可以使用 UserProfile.objects.all() 访问用户配置文件。

{{ 用户。 }} 工作正常，所以我认为这是我的模型的问题，但我检查了 Django 文档“模型”、“数据库查询”和“模型实例引用”以及相关的 S/O 帖子，但如果它是我的模型这就是问题所在，我不知道还要搜索什么。

谢谢

Answer 1

您在UserProfile 模型的外键上设置了related_name='user'，这意味着您必须使用user.user 访问它。

related_name defines how you access the reverse relationship，而不是前向，因此将其设置为 user 有点令人困惑，并且可能不是您希望它工作的方式。

您可以考虑将related_name 更改为"profile"，以便您可以以user.profile 的身份访问它。

Answer 2

将 related_name 从 user 更改为 userprofile

user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='userprofile')

并且不要忘记将用户传递到上下文中。
