我收到此错误

＃PostsController：0xd034f28>的未定义局部变量或方法`resource_class'

请在这里是我的应用程序控制器

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  before_action :configure_permitted_parameters, If: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:name])
    devise_parameter_sanitizer.permit(:account_update, keys: [:name])
  end     
end

我的职位控制者

class PostsController < ApplicationController
    before_action :find_post, only: [:show, :edit, :update, :destroy]
    before_action :authenticate_user!, except: [:index, :show]

    def index
        @posts = Post.all.order("created_at DESC")
    end

    def show
    end

    def new
        @post = current_user.posts.build
    end

    def create
        @post = current_user.posts.build(post_params)
        if @post.save
            redirect_to @post
        else
            render 'new'
        end
    end

    def edit        
    end

    def update
        if @post.update(post_params)
            redirect_to @post
        else
            render 'edit'
        end
    end

    def destroy
        @post.destroy
        redirect_to root_path
    end

    private

    def find_post
        @post = Post.find(params[:id])
    end

    def post_params
        params.require(:post).permit(:title, :link, :description)
    end
end
