Rails：如何在視圖中而不是application.html.erb中包括元標記？

[英]Rails: How to include meta tags in views and not in application.html.erb?

原文 2013-06-26 12:20:05 0 1 ruby-on-rails/ ruby-on-rails-3/ meta-tags

我想在首頁視圖中包含元標記。 但是我不想直接將它包含在application.html.erb文件的頭部，因為這將導致它在所有頁面上包含meta標簽，這對我的應用程序來說是多余的。

1 個解決方案

你可以放

<% if content_for?(:head) %>
  <%= yield(:head) %>
<% end %>

在application.html.erb布局的head部分。

然后，在要包含這些標簽的視圖中：

<% content_for :head do %>
  <!-- your tags -->
<% end %>
