* Converts queries to use active record instead of raw sql. This ensures that user objects are loaded by rails in the join, so that we don't have to issue `User.find` calls to load users one-by-one. * Use `.includes` to preload associations used in the view, to avoid additional N+1 query problems (primarily, calls to link_to_user also causing users to be loaded one-by-one).
