红宝石新手在这里。我正在关注 Rails 教程并被困在 5.3 re: routes 附近。

我有 5 页（主页、关于、帮助、联系方式），都具有类似的测试集，而 rspec 仅在“主页”上的测试中失败。由于我使用的是 application_helper，所以我不需要在 home.html.erb 中指定，对吧？我还接受了了解 Rails 路由的建议：在 routes.rb 中匹配与根，并在 routes.db 中添加了“match '/static_pages/home' => 'static_pages#home'”。

一直停留在这两个错误上。请帮忙。谢谢！

错误：

1) Static pages Home page should have the h1 'Sample App'
Failure/Error: page.should have_selector('h1', text: 'Sample App')
expected css "h1" with text "Sample App" to return something
# ./spec/requests/static_pages_spec.rb:9:in `block (3 levels) in <top (required)>'

2) Static pages Home page should have the base title
Failure/Error: page.should have_selector('title',
expected css "title" with text "Ruby on Rails Tutorial Sample App" to return something
# ./spec/requests/static_pages_spec.rb:13:in `block (3 levels) in <top (required)>'

主页.html.erb

<div class="center hero-unit">
<h1>Welcome to the Sample App</h1>

<h2>
This is the home page for the
<a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
sample application.
</h2>

<%= link_to "Sign up now!", '#', class: "btn btn-large btn-primary" %>
</div>

<%= link_to image_tag("rails.png", alt: "Rails"), 'http://rubyonrails.org/' %>

static_pages_spec.rb

require 'spec_helper'

describe "Static pages" do

  describe "Home page" do

  it "should have the h1 'Sample App'" do
    visit root_path
    page.should have_selector('h1', text: 'Sample App')
  end

  it "should have the base title" do
    visit root_path
    page.should have_selector('title', text: "Ruby on Rails Tutorial Sample App")
  end

  it "should not have a custom page title" do
    visit root_path
    page.should_not have_selector('title', text: '| Home')
  end
end

应用程序.html.erb

<!DOCTYPE html>
<html>
  <head>
    <title><%= full_title(yield(:title)) %></title>
    <%= stylesheet_link_tag    "application", media: "all" %>
    <%= javascript_include_tag "application" %>
    <%= csrf_meta_tags %>
    <%= render 'layouts/shim' %>    
  </head>
  <body>
    <%= render 'layouts/header' %>
    <div class="container">
      <%= yield %>
      <%= render 'layouts/footer' %>
    </div>
  </body>
</html>

application_helper.rb

module ApplicationHelper

# Returns the full title on a per-page basis.
def full_title (page_title)
    base_title = "Ruby on Rails Tutorial Sample App"
    if page_title.empty?
        base_title
    else
        "#{base_title} | #{page_title}"
    end
end

end

路线.rb

SampleApp::Application.routes.draw do
  match '/help',    to: 'static_pages#help'
  match '/about',   to: 'static_pages#about'
  match '/contact', to: 'static_pages#contact' 
  match '/static_pages/home' => 'static_pages#home'

  root to: 'static_pages#home'
end

需要帮助请叫我。谢谢！

您是否删除了 public/index.html 文件并直观地验证了您可以在浏览器中访问 /，并且正在呈现预期的模板？否则，您的规格看起来不错。
