Question

我试图运行这个rspec测试：

  describe "quotes#approve action" do
    it "should successfully change boolean called approved to true" do
      get :approve
      expect(@quote).to have_attributes(:approved => true)
      expect(flash[:success]). to be_present
      expect(response).to redirect_to admin_path
    end
  end

应从控制器调用此代码。

  def approve
    @quote.approved = true
  end

但是当我运行此测试时，我收到此错误

 Failure/Error: @quote.approved = true

 NoMethodError:
   undefined method `approved=' for nil:NilClass

我相当肯定这与我的@quote变量未分配有关，但即使在批准方法中设置布尔值之前，似乎也没有什么区别。由于这是我第一次遇到这样的问题，我不太确定从哪里开始调试它。

编辑：

我将rspec测试更改为：

  describe "quotes#approve action" do
    it "should successfully change boolean called approved to true" do

      @quote = Quote.create(author: 'Test', saying: 'Hello!')
      get :approve, id: @quote.id
      expect(@quote).to have_attributes(:approved => true)
      expect(flash[:success]). to be_present
      expect(response).to redirect_to admin_path
    end
  end

和控制器代码：

  def approve
    @quote = Quote.find(params[:id])
    @quote.approved = true
  end

这似乎让我更进一步，因为我不再得到NoMethodError，但我现在得到一个新的错误，即：

 Failure/Error: expect(@quote).to have_attributes(:approved => true)

   expected #<Quote id: 102, author: "Test", saying: "Hello!", created_at: "2017-05-02 21:13:52", updated_at: "2017-05-02 21:13:52", approved: false> to have attributes {:approved => true} but had attributes {:approved => false}
   Diff:
   @@ -1,2 +1,2 @@
   -:approved => true,
   +:approved => false,

我相当肯定这只是意味着我的控制器代码无法正常工作，但我还没有能够弄清楚到底出了什么问题。

使用布尔
