Django ORM 可以对列的特定值执行 ORDER BY 吗?

2022-01-01 00:00:00 python django orm mysql

我有一张包含以下列的票"表

I have a table 'tickets' with the following columns

id - 主键 - 自增
标题 - varchar(256)
status - smallint(6) - 可以是 1 到 5 之间的任何值，由 Django 处理

当我执行 SELECT * 我希望 status = 4 位于顶部的行时，其他记录将跟随它们.可以通过以下查询来实现:

When I'll do a SELECT * I want the rows with status = 4 at the top, the other records will follow them. It can be achieved by the following query:

select * from tickets order by status=4 DESC

这个查询可以通过 Django ORM 执行吗?哪些参数应该传递给 QuerySet.order_by() 方法?

Can this query be executed through Django ORM? What parameters should be passed to the QuerySet.order_by() method?

推荐答案

q = Ticket.objects.extra(select={'is_top': "status = 4"}) q = q.extra(order_by = ['-is_top'])
