双重外键在Django？ [英] Double Foreign Key in Django?

问题描述

例如，如果我有表：audio，overlay，html
和表：timeline_item它有一个字段ID和一个字段类别，指定音频，覆盖，或HTML ...

有谁知道我将如何在Django建模？或者甚至是可能的？

解决方案

听起来像是一个多态关联。也许你可以用Django的泛型关系解决你的问题，使用 ContentTypes 框架。

Is there anyway to model double foreign keys in Django?

For instance if I had tables: audio, overlay, html and the table: timeline_item which has a field id, and a field category which specifies audio, overlay, or html...

Does anyone know how I would go about modeling this in Django? or if it's even possible?

解决方案

Sounds like a polymorphic association. Maybe you can solve your problem with Django's generic relations using the ContentTypes framework.
