Rails 教程 haml

Question

我决定将 ruby​​ on rails 教程从 erb 更改为 haml。我现在正在体验这个输出：

     FAIL["test_should_get_home", StaticPagesControllerTest, 0.066385842]
     test_should_get_home#StaticPagesControllerTest (0.07s)
    <Home | Ruby on Rails Tutorial Sample App> expected but was
    <Home

    Expected 0 to be >= 1.
    test/controllers/static_pages_controller_test.rb:11:in `block in  <class:StaticPagesControllerTest>'

    Expected 0 to be >= 1.
       test/controllers/static_pages_controller_test.rb:17:in `block in    <class:StaticPagesControllerTest>'

这是 application.rb 文件：

  %html
   %head
%meta{:content => "text/html; charset=UTF-8", "http-equiv" => "Content-Type"}/
%title
  = yield(:title)
  | Ruby on Rails Tutorial Sample App
= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true
= javascript_include_tag 'application', 'data-turbolinks-track' => true
= csrf_meta_tags
%body
= yield

所以问题是我如何让haml在测试期间将其读为一行？

提前感谢您的帮助。

要获得您想要的结果，请从 HTML 中删除换行符：

= "#{yield :title} | Ruby on Rails Tutorial Sample App"
