Body
I been trying to add another joins table like shown in rails guide(e.g. publication_comments). Then I call select on specified columns to count, probably so far it's working. Idea of this is to plus reviews_count and pub_count = SUM. however I faced a problem how to plus in query reviews_count and pub_count and order: "SUM DESC". Is it possible to make like I think? and how? So far I have this code: <pre><code> @publication = Publication.joins(:reviews, :publication_comments) .select('"publications".*, count("reviews".id) as reviews_count, count("publication_comments".id) as pub_count') .group('"publications".id') .order("reviews_count DESC") </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
