Including instance methods to JSON output

Use :methods parameter to include ActiveRecord instance methods to JSON output. :only and :except uses DB columns only.

@events.to_json(:include => { 
                  :images => { 
                    :only => [], :methods => [:public_url] }})

In the previous example events have multiple images and only public_url instance method is included in the JSON output.
