# Just example. Feel free to use it and modify to your needs.

# ArticlePage - my model
# ArticleTag - m2m model for my tags (TaggedItemBase)
# taggit_tag - Taggit tag model
# (1, 2, 3) - just example tag ids
ArticlePage.objects.raw('select a.page_ptr_id, p.title, count(at.tag_id) as tag_count from article_articlepage a join wagtailcore_page p on a.page_ptr_id = p.id join article_articletag at on at.content_object_id = a.page_ptr_id join taggit_tag t on t.id = at.tag_id where tag_id in (1, 2, 3) group by (page_ptr_id, p.id) order by tag_count desc');
