Question

我在models/ability.rb

中有这个

class Ability
  include CanCan::Ability

  def initialize(user)
    user ||= User.new   

    if user.role? :registered
      can :read Post
    end

  end

当我在rails console上执行此操作时

#this returns a user with a role: "registered" attribute   
user = User.first
post = Post.first
ability = Ability.new(user)

### This returns false ###
ability.can?(:read, post)
#=> false

我编写的这个规范测试能力也失败了，而我希望它能够通过。

describe User, :type => :model do
  let(:post) {create(:post)}
  describe "abilities" do
    subject(:ability){Ability.new(user)}
    let(:user){nil}

     context "when is a registered user" do

       ## the default value for the role attribute in the user factory is "registered"
       let(:user) {create(:user)}
       it {is_expected.to be_able_to :read, post}
     end
  end
end

当我在浏览器上作为注册用户进行身份验证时，我可以访问和阅读/posts和/posts/:id中的帖子，我不知道为什么它在rails console和rspec中都失败了。< / p>

Answer 1

在discussion之后，我们得出结论，问题是

Rails没有加载Ability类，或
代码某处以某种方式覆盖了Ability类。

解决方法 - 解决方案是通过在application.rb

require "#{Rails.root/app/models/ability.rb}"

在rails控制台和Rspec中，Cancancan能力调试失败
