Question

I have users with nested resources posts. I have a page that shows all posts from all users. However, on the left column I want to categorize them by user, as follows, with links to a URL with a parameter like ?username=laura, for example, to show only their posts. I’m pretty sure I can figure out the URL params, but getting them sorted, as shown below, is difficult for me. Any suggestions? Thanks!

Adam (23)

Brad (12)

Mike (1)

Answer 1

Users.includes(:posts).map{|u| [u.name, u.posts.count, u.id]}.sort

Will give you a sorted array of users, post counts, and user id like

[
 ["Adam", 23, 23],
 ["Brad", 12, 2],
 ["Mike", 1, 44]
]

You can this user the first two elements for your link and the user id for the link destination.

This might get slow with thousands of users and/or posts, but it should get you started.
