过滤在Django中的prefetch_related [英] Filter on prefetch_related in Django

问题描述

有没有办法过滤预取的对象？我需要获取最新的（）预取对象，但是如果您使用最新的，因为查询更改，则prefetch_related不起作用？

但我希望有一个更简单的解决方法...

解决方案

截至Django 1.7，可以过滤预取的对象。请参阅此SO答案和 Django文档。

Is there a way of filtering prefetched objects? I need to get the latest() of the prefetched objects but prefetch_related doesn't work if you use latest because the query is changed?

The example here does what I need but I was hoping there's a simpler workaround...
