Has Many Associations As Columns

[JoshuaNovak919]

Is there a way to show a has many association as columns in an export? Basically i'm trying to have the user export have a column for each group with the header being the group name and the data being the date the group was created. Is there currently a way to do this?

Hi joshua,

I'd recommend making a custom method, delegate or use a lambda, or simply using the hash syntax.

eg. (given pages has a 'title')

class Book < ActiveRecord::Base
   has_many   :pages
   delegate :title, :to => :page

   comma do

     name
     description

     pages :title => 'This is a custom header for page title'
     title
     custom_method_title
   end

   def custom_method_title
     pages.find('x).title
   end
 end

cheers,

Tom
