我正在尝试按照他们的评论数量在django中订购商品列表。但是，似乎存在一个问题，即Count函数没有考虑到django注释还使用content_type_id来区分不同对象的注释这一事实！
这给我一个小问题，因为使用标准方法对所有对象的注释计数是错误的;是否有一个“好的”修复或者我是否需要回退到原始的SQL？
尝试和正确排序的代码：
app_list = App.objects.filter(published=True)
.annotate(num_comments=Count('comments'))
.order_by('-num_comments')
查询的示例输出（注意没有提及内容类型ID）：
SELECT "apps_app"."id", "apps_app"."name",
"apps_app"."description","apps_app"."author_name", "apps_app"."site_url",
"apps_app"."source_url", "apps_app"."date_added", "apps_app"."date_modified",
"apps_app"."published", "apps_app"."published_email_sent", "apps_app"."created_by_id",
"apps_app"."rating_votes", "apps_app"."rating_score", COUNT("django_comments"."id") AS
"num_comments" FROM "apps_app" LEFT OUTER JOIN "django_comments" ON ("apps_app"."id" =
"django_comments"."object_pk") WHERE "apps_app"."published" = 1 GROUP BY
"apps_app"."id", "apps_app"."name", "apps_app"."description", "apps_app"."author_name",
"apps_app"."site_url", "apps_app"."source_url", "apps_app"."date_added",
"apps_app"."date_modified", "apps_app"."published", "apps_app"."published_email_sent",
"apps_app"."created_by_id", "apps_app"."rating_votes", "apps_app"."rating_score" ORDER
BY num_comments DESC LIMIT 4
