ActiveRecord Where Assoc
-
EXISTS clause for active record

My new gem lets you follow associations when doing ActiveRecord queries. Here's an intro for follow_assoc.
Your examples using joins would return duplicated Sections. That might force you to add a distinct. I personally find it wrong to do a distinct in a scope just to be able to make the condition I want the scope to do. It's a hidden side effect that could cause problem elsewhere and it's unexpected from the name of the scope. I made a gem to deal with that situation: where_assoc. There is definitely an overlap between both gem.
