def self.patch_base_classes
  [Object, Array, FalseClass, Float, Hash, Integer, NilClass, String, TrueClass].each do |klass|
    klass.class_eval do
      def to_json(opts = {})
        MultiJson::dump(self.as_json(opts), opts)
      end
    end
  end
end

.patch_renderers ⇒ Object

Use multi_json instead of Rails’ to_json method (which calls ActiveSupport::JSON) when ‘render :json => @obj` is called.
