Spawn methods #rails

Post.where(published: true).joins(:comments).merge( Comment.where(spam: false) ) # Performs a single join query with both where conditions. recent_posts = Post.order('created_at DESC').first(5) Post.where(published: true).merge(recent_posts) # Returns the intersection of all published posts with the 5 most recently created posts. # (This is just an example.
