Can''t quite figure this one, I have a School (has_many reviews) and a Review (belongs_to school). I''m rendering my reviews per school like this "@School.reviews" Which renders the "_review.html.erb" multiple times for reviews of that school (works a treat). But how do I control the order in which these are displayed (I''d like to reverse them basically most recent on top). bb. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

this should work:
@school.reviews.sort_by { |cc| - cc.updated_at.to_i }

class School < AR has_many :reviews, :order => ''created_at DESC'' end class Review < AR belongs_to :school end If you use @school.reviews you''ll get the desired effect....

That''s ideal! thanks. Follow up question, what if I want to override this order from time to time, say on some occasions have the reviews sorted by their last_name column? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You could use named_scope to get more complexity. I think that''s a possibility. http://www.locomotivation.com/blog/2008/08/25/simplify-activerecord-aggregates-and-other-goodies-via-named-scope.html bingo bob escribió:> That''s ideal! thanks. > > Follow up question, what if I want to override this order from time to > time, say on some occasions have the reviews sorted by their last_name > column? >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Bob, You could also render it with jquery or some javascript library that enables you to write the set of reviews once to javascript and present and re-present in multiple ways as needed without more roundtrips to the server.
