Failed examples:

我的routes.rb文件是

Sample::Application.routes.draw do
 root to: 'static_pages#home'

match '/help', to: 'static_pages#help'
match '/contact', to: 'static_pages#contact'
match '/about' , to: 'static_pages#about'
  end

我的_header.html.erb代码是

<header class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<%= link to "sample app", '#', id: "logo" %>

<nav>
<ul class="nav pull-right">
<li><%= link_to "Home",  '#' %></li>
<li><%= link_to "Help", '#' %></li>
<li><%= link_to "Sign in", '#' %></li>
</ul>
</nav>
</div>
</div>
</header>

和application.html.erb代码是

<!DOCTYPE html>
<html>
<head>
<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", media: "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>

</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<%= yield %>
<%= render 'layouts/footer' %>
</div>
</body>
</html>

任何人都可以帮助我为什么我得到这个未定义的方法错误以及如何摆脱它??

Answer 1

试试这个：

Sample::Application.routes.draw do
   match '/help' => 'static_pages#help'
   match '/contact' => 'static_pages#contact'
   match '/about' => 'static_pages#about'
   root :to => 'static_pages#home'
end

Answer 2

你可能在_header文件中输入了一个拼写错误，因为每个错误都有它，再次检查_header文件，如果你运行rails服务器并尝试访问这些页面，你应该得到相同的错误。

ActionView :: Template ::错误：未定义的方法`到'
