Django-通过排序将两个查询集合并 [英] Django - merge two querysets by sorting them

问题描述

我有两个模型，我正在像这样查询它们：

i have two models and i am querying them like this:

firstq = FirstModel.objects.order_by('-addedtime')
secondq = SecondModel.objects.order_by('-addedtime')

我要并按 appededtime 字段对它们进行排序。他们俩都有此字段。

I want to merge and sort them by addedtime field. they both have this field..

我该怎么做？

| 仅在我有2个来自相同模型的查询时有效。但是我这里有2种不同的模型。

| works only if i have 2 queries from same model. But i have 2 different models here..

推荐答案

您执行的操作如下：

 from itertools import chain
 result_list = list(chain(firstq, secondq))
