Hello, I have a Post that has_many Comments. I have the next scopes:
scope :valid, where('created_at >= ?', 2.months.ago)
scope :expired, where('created_at < ?', 2.months.ago)
Now, I would have a scope named :commented that return all the Post
that have more than 0 Comments but I don't know how do it clearly. A
solution is have a counter num_comments column in Post, but I don't
know if that is the best practice.
Thanks for your advices. Bye.
Daniel
