Model extension to simplify access to seed data

has_seed_data.rb

# has_seed_data.rb
module HasSeedData

  def self.included(model)
    model.extend(ClassMethods)
    model.send(:instance_variable_set, :@seeds, MyApp::Application.data_seeds[model.table_name.to_sym].seeds)
  end

  module ClassMethods
    def seeds; @seeds; end
  end

end

# usage ...
class FlagType < ActiveRecord::Base
  include HasSeedData
end

# allows slightly more clear and terse access to the seed data
FlagType.seeds[:example][:id]

# vs the more vebose access methods
MyApp::Application.data_seeds[:flag_types][:example][:id]
Rails.data_seeds[:flag_types][:example][:id]
