Copy this code and paste it in your HTML 
  1. # Always be on the lookout for duplicated code. If you find yourself doing 
  2. # asset.incomings.find(:all, :limit => 10) in multiple places, then perhaps you need to 
  3. # pull that into a method of its own. Given the use of the magic number "10", it might
  4. # not be a bad idea to do so anyway.
  5.  
  6. class Asset < ActiveRecord::Base
  7.   has_many :incomings do
  8.     def recent(count=10)
  9.       find(:all, :limit => count)
  10.     end
  11.   end
  12. end
  13.  
  14. # Then, you just have to do @asset.incomings.recent to get the first 10 items.
