Difei,
If a comment only belongs to either an article, movie or a photo
(never more than one) you could add methods in the model to determine
which it is for.
For example:
class Comment
def article_comment?
!article_id.nil?
end
end
@comment.article_comment? will return true if this is a comment for an
article and false if not.
You could render your view accordingly for each type of comment.
Hope that helps?
