在Django中通过SQL创建组的问题

Question

我有以下django查询集：

     hero = DeedUser.objects\
    .select_related('user')\
    .values('user_id', 'user__display_name')\
    .annotate(total_deed=Count('user_id'))

并返回以下内容：

SELECT "deeds_deeduser"."user_id", "users_user"."display_name", COUNT("deeds_deeduser"."user_id") AS "total_deed" FROM "deeds_deeduser" INNER JOIN "users_user" ON ( "deeds_deeduser"."user_id" = "users_user"."id" ) GROUP BY "deeds_deeduser"."user_id", "users_user"."display_name", "deeds_deeduser"."modified", "deeds_deeduser"."created" ORDER BY "deeds_deeduser"."modified" DESC, "deeds_deeduser"."created" DESC LIMIT 21

为什么它将字段已修改和已创建添加到 GROUP BY ，因为我已在select_related（）中指定了该值

Answer 1

我添加了

.order_by('total_deed') 

现在有效。
