Django使用group by获得多个coloumn

Question

TagNews.objects.filter(status=1).values("news","tag").annotate(total=Count('tag'))

SELECT `tags_news`.`news_id`,
       `tags_news`.`tag_id`,
        COUNT(`tags_news`.`tag_id`) AS `total`
  FROM `tags_news`
 WHERE `tags_news`.`status` = 1
 GROUP BY `tags_news`.`news_id`,
          `tags_news`.`tag_id`
 ORDER BY NULL

但我想要多个列字段和单个组，如下面的查询： -

SELECT `tags_news`.`news_id`,
       `tags_news`.`tag_id`,
        COUNT(`tags_news`.`tag_id`) AS `total`
  FROM `tags_news`
 WHERE `tags_news`.`status` = 1
 GROUP BY `tags_news`.`tag_id`
 ORDER BY NULL

Answer 1

如果我理解正确，您希望将TagNews与tag分组，那么请获取tag和news列。这应该可行;

tag_news = TagNews.objects.filter(status=1).values("tag").annotate(total=Count('tag'))
tag_news.values("news","tag")
