将 TastyPie ModelResource 添加到通过 Django OneToOne 关系连接的另一个 ModelResource
我有两个通过 OneToOne 关系连接的 django 模型，但我无法了解如何在 Tastypie ModelResource 中连接它们。
我不会发布一些新模型，而是借用 中定义的模型，包括子资源在 Django Tastypie API 中显示我不知道如何执行此操作的地方。使用 Ticket 和 TicketComment 模型，想象一下 TicketComment 是这样的：
class TicketComment(models.Model):
ticket = models.OneToOneField('Ticket')
而不是使用foreignkey字段。我已经看过使用 ToManyField 和 ToOneField 的文档以及类似上面的帖子。但这似乎不适用于我的情况，因为 Ticket 没有引用 TicketComment。我想要做的是能够创建一个 API，在 Ticket 中列出 TicketComment。 Tastypie 正确地抛出异常，指出 Ticket 模型中不存在 TicketComment 字段。有没有办法将漂亮的序列化 TicketComment 放入 Ticket API 中？
I have two django models that are connected by a OneToOne relationship and I am having trouble seeing how to connect them in a Tastypie ModelResource.
Instead of posting some new models I will borrow the models defined in Including child resources in a Django Tastypie API to show where I am not getting how to do this. Using the Ticket and TicketComment models, imagine that the TicketComment was like this:
class TicketComment(models.Model):
ticket = models.OneToOneField('Ticket')
instead of using the ForeignKey field. I have seen the docs as well as posts like the above which are using the ToManyField and ToOneField. But that doesn't appear to work in my situation since the Ticket does not reference the TicketComment. What I want to do is be able to create an API that lists the TicketComment in the Ticket. Tastypie rightly throws an exception saying that TicketComment fields don't exist in the Ticket model. Is there a way to get the nice serialized TicketComment into the Ticket API?

有一个 attribute arg 告诉 tastypie 应该使用哪个字段。 Ticket 通过反向关系引用 TicketComment。默认情况下，它将是小写的模型名称，因此在您的示例中它将是票证评论。但我建议您设置 related_name显式地在模型中添加 属性，以便您知道它将如何连接。
所以在你的美味馅饼中你应该这样做：
它会工作得很好。 OneToOneField 中的第二个参数是一个属性。
There is an attribute arg that tells tastypie what field it should use. Ticket is referenced TicketComment by reverse relation. By default it will be a lowercased model name so in your example it will be ticketcomment. But i recommend you to set a related_name attribute in your model explicitly so you will know how it will be connected.
So in your tastypie you should do this :
And it will work fine. The second arg in OneToOneField is a attribute.
