KeyError with `similar_objects()` function

[ddlaws0n]

Hi Alex,

I'm working on a project using Wagtail-CMS which incorporates your tagging system. For what I'm working on at the moment the similar_objects() function you created is exactly what I need, however I think there might be an issue with the function (unless I'm making some silly mistake in my own code).

I've written up a detailed post on SO which you can check out here.

Many thanks

Stuck with the same problem. Eventually I decided to use raw sql to perform my query. I wrote this way (It is just workaround, not solution to original problem.):

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');

I put this into gist with better explanation, so feel free to copy and modify it if you needed: https://gist.github.com/prokaktus/bd805e3f9a3eabb64be22523ae5fdf66

I'm having the same issue and seems like this pr #424 is kind of stuck for the last few years.

This seems to be a duplicate of #80
