Ruby on rails rails中helper方法的问题

我有以下助手方法（app/helpers/application\u helper.rb）：

下面是erb（app/views/layouts/application.html.erb）：

但是，我仍然在您的视图中遇到相同的错误，默认情况下不包括帮助程序

你可以：

然后，您可以单独测试您的应用程序

或者，只需执行以下操作，即可将助手包括在视图规范中：

include ApplicationHelper

编辑

describe PagesController do
  include ApplicationHelper

  describe "GET 'home'" do
    it "should be successful" do
      controller.template.should_receive(:title).and_return("Title")
      get 'home'
      response.should be_success
    end
  end
end

---

我应该将include ApplicationHelper放在哪里？如果我没记错，它需要放在descripe块中。“编辑”刚找到这个链接很抱歉，当您提到帮助器方法时，我假设您正在测试一个视图。你试过stubing方法吗？我对rspec不太熟悉，所以我不知道该放在哪里，它说放在模板对象中，但它在哪里？请查看我的编辑，并告诉我这是否有效。我也建议退房
