Проблема с load_resource в рельсах 4

Question

Это мой PostersController! Мне просто хотелось бы, чтобы кто-нибудь сказал мне, как заставить его работать с «load_resource». «authorize_recourse» работает хорошо, но что мне нужно изменить, чтобы load_resources работали? Я предлагаю я должен сделать что-то с сильными Params .. Спасибо

class PostersController < ApplicationController 
    before_action :set_poster, only: [:show, :edit, :update, :destroy]

    # Never trust parameters from the scary internet, only allow the white list through. 
    def poster_params 
     params.require(:poster).permit(:title, :body, :publish_date, :type) 
    end 
end
