這裏是我的索引的副本

<h1>Listing posts</h1> 

<table> 
    <tr> 
    <th>Title</th> 
    <th>Content</th> 
    <th></th> 
    <th></th> 
    <th></th> 
    </tr> 

<% @posts.each do |post| %> 
    <tr id="<%= dom_id(post) %>"> 
    <td><%= post.title %></td> 
    <td><%= post.content %></td>

HTML頁面後這裏是我的策略頁複印件

class ApplicationPolicy 
    attr_reader :user, :record 

    def initialize(user, record) 
    raise Pundit::NotAuthorizedError, "must be logged in" unless user 
    @user = user 
    @record = record 
    end 

    def index? 
    false 
    end 

    def show? 
    scope.where(:id => record.id).exists? 
    end 

    def create? 
    false 
    end 

    def new? 
    create? 
    end 

    def update? 
    false 
    end 

    def edit? 
    update? 
    end 

    def destroy? 
    false 
    end 

    def scope 
    Pundit.policy_scope!(user, record.class) 
    end 
end 

class PostPolicy < ApplicationPolicy 
    class Scope < Struct.new(:user, :scope) 
    def resolve 
     scope 
    end 
    end 
end

我的用戶模型，我斯塔用色器件和我的職位模型LLED

class User < ActiveRecord::Base 
    attr_accessible :role, :published 

    def author? 
    role == 'author' 
    end 

    def editor? 
    role == 'editor' 
    end 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 

    # Setup accessible (or protected) attributes for your model 
    attr_accessible :email, :password, :password_confirmation, :remember_me 
    # attr_accessible :title, :body 
    has_many :posts, foreign_key: "author_id" 
end 


class Post < ActiveRecord::Base 
    attr_accessible :content, :title 
    belongs_to :author, class_name: "User" 

    def publish! 
    published = true 
    save! 
    end 
end

，也是我的帖子控制器

對不起弄清這一點對我來說就像在乾草堆發現一針任何人都可以點我在正確的方向？
