ActiveRelation merge, a hidden merge

Scopes are a neat feature of Rails 3, but what happens when you need to use a scope from an associated model to filter something on the current model. Imagine you have a User that has many articles through a Collaboration model. Now you have an article and you want to get the users that were editors on that article with a single query. The collaboration already has an editorial scope so why not use that? With Arel merge you can do exactly that, effectively using another model’s scope to filter a query.
