module Tire::Model::Callbacks

Main module containing the infrastructure for automatic updating of the Elasticsearch index on model instance create, update or delete.

Include it in your model: `include Tire::Model::Callbacks`

The model must respond to `after_save` and `after_destroy` callbacks (ActiveModel and ActiveRecord models do so, by default).

A hook triggered by the `include Tire::Model::Callbacks` statement in the model.

# File lib/tire/model/callbacks.rb, line 16
def self.included(base)

  # Update index on model instance change or destroy.
  #
  if base.respond_to?(:after_save) && base.respond_to?(:after_destroy)
    base.send :after_save,    lambda { tire.update_index }
    base.send :after_destroy, lambda { tire.update_index }
  end

  # Add neccessary infrastructure for the model, when missing in
  # some half-baked ActiveModel implementations.
  #
  if base.respond_to?(:before_destroy) && !base.instance_methods.map(&:to_sym).include?(:destroyed?)
    base.class_eval do
      before_destroy  { @destroyed = true }
      def destroyed?; !!@destroyed; end
    end
