module ActionController # Action Controller Serialization # # Overrides render :json to check if the given object implements +active_model_serializer+ # as a method. If so, use the returned serializer instead of calling +to_json+ in the object. # # This module also provides a serialization_scope method that allows you to configure the # +serialization_scope+ of the serializer. Most apps will likely set the +serialization_scope+ # to the current user: # # class ApplicationController < ActionController::Base # serialization_scope :current_user # end # # If you need more complex scope rules, you can simply override the serialization_scope: # # class ApplicationController < ActionController::Base # private # # def serialization_scope # current_user # end # end # module Serialization extend ActiveSupport::Concern include ActionController::Renderers included do class_attribute :_serialization_scope self._serialization_scope = :current_user end def serialization_scope send(_serialization_scope) if respond_to?(_serialization_scope) end def default_serializer_options end def _render_option_json(json, options) if json.respond_to?(:to_ary) options[:root] ||= controller_name unless options[:root] == false end serializer = options.delete(:serializer) || (json.respond_to?(:active_model_serializer) && json.active_model_serializer) if serializer options[:scope] = serialization_scope options[:url_options] = url_options json = serializer.new(json, options.merge(default_serializer_options || {})) end super end module ClassMethods def serialization_scope(scope) self._serialization_scope = scope end end end end
