Ruby on rails 查找：包含-使用rspec测试控制器

我在rails应用程序中有一些操作

  def show
    @issue = Issue.find(params[:id], :include => [:answers, :comments])
    @answers = @issue.answers
    @comments = @issue.comments

    respond_to do |format|
      format.html # show.html.erb
      format.xml  { render :xml => @issue }
    end
  end

和rspec试验

  def mock_issue(stubs={})
    @mock_issue ||= mock_model(Issue, stubs)
  end


  describe "GET show" do
    it "assigns the requested issue as @issue" do
      @issue = mock_issue
      @answers = mock("answers")
      @comments = mock("comments")

      Issue.stub(:find).with("37").and_return(@issue)
      @issue.stub(:answers).and_return([@answers])
      @issue.stub(:comments).and_return([@comments])

      get :show, :id => "37"
      assigns[:issue].should equal(@issue)
    end
  end

在尝试运行以下测试时，我看到错误

NoMethodError in 'IssuesController GET show assigns the requested issue as @issue'
undefined method `find' for #<Class:0x105dc4a50>

“IssuesController GET show”中的NoMethodError将请求的问题分配为@issue 未定义的方法“查找”#

但是如果没有：include=>[：answers，：comments]它就可以正常工作。你能告诉我吗？有没有办法存根：包括？

哦，我可以回答我的问题：）

 Issue.stub(:find).with("37", :include => [:answers, :comments]).and_return(@issue)
