Question

Looking for a simple method utilizing active record to grab data from two models, combine the data, and then sort the combined output by created_at.

For example:

assume two models, Comment & Like both belongs_to User

return a combined list of @user’s comments and likes sorted by date

I know I can do this in SQL but I’d really like an active record solution.

Thanks!

Answer 1

I believe it should be as simple as:

combined_sorted = (User.comments + User.likes).sort{|a,b| a.created_at <=> b.created_at }
