Ruby on rails -Метод PUT при обновлении ajax

Может кто-нибудь сказать мне, почему этот метод PUT не работает, пожалуйста.

$.ajax({
        type: "PUT",
        dataType: "script",
        url: '/resources/35',
        data:
        {
            resource : { pos_y: 45, pos_x: 50 }
        }
    }).done(function( msg )
            {
                alert( "Data Saved: " + msg );
            });

Сервер говорит, что я использовал метод GET , но в моем запросе ajax у меня есть тип :"PUT"

ресурсы _controller.rb

 # PUT /resources/1

  def update
    @resource = Resource.find(params[:id])

    respond_to do |format|
      if @resource.update_attributes(params[:resource])
        format.html { redirect_to @resource, notice: 'successfully updated.' }
        format.js
      else
        format.html { render action: "edit" }
        format.js
      end
    end
  end

Я попытался добавить_метод :'положить' Но это все то же самое

$.ajax({
        type: "PUT",
        dataType: "script",
        url: '/resources/35',
        data:
        {
            resource : { pos_y: 45, pos_x: 50 },
            _method: 'put'
        }
    }).done(function( msg )
            {
                alert( "Data Saved: " + msg );
            });

Сервер:
