Hi guys,
I have the following problem:
In my application there is 3 entities that have this relationship:
-1 post has many comments
-1 comment belongs to one user and to one post
-1 comment could be voted by many users
My problem is how can I make a query to search for the best rated
comment, in other words, How can I get the comment from one user which
has the most quantity of good votes?
I don’t know how to make this query… ;/
my entities are structure like this:
class Post < ActiveRecord::Base
belongs_to :user
belongs_to :post_type
has_many :post_comments
end
class PostComment < ActiveRecord::Base
belongs_to :user
belongs_to :post
has_many :post_comment_votes
end
class PostCommentVote < ActiveRecord::Base
belongs_to :vote_type
belongs_to :user
belongs_to :post_comment
end
class VoteType < ActiveRecord::Base
has_many :post_comment_votes
end
Thx ;D
