ActiveRecord Virtual Attributes treaded as a record attributes

Question

I am running into a problem with to_json not rendering my virtual attributes

class Location < ActiveRecord::Base
    belongs_to :event
    before_create :g         


        

Answer 1

Simply implement #to_json yourself then:

class Location < ActiveRecord::Base
  def to_json(options={})
    options[:methods] ||= []
    options[:methods] << :event_oid
    super(options)
  end
end
