sorting a has_many collection

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).

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

3

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....

You could use named_scope to get more complexity. I think that's a possibility.

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.
