如何将css / sass样式表关联到rails中的视图？ [英] How do you associate a css/sass stylesheet to a view in rails?

问题描述

这是一个非常普通的问题，我没有找到一个简单的答案。

This is a really generic question, to which I haven't found a simple answer.

我处理的凌乱的旧代码，相同的类/视图。我有 app / styles 中的.sass文件， public / stylesheets 和 public / css

I'm dealing with messy legacy code that specifies style several times for the same classes/views. I have .sass files in app/styles, .css files in public/stylesheets and public/css

我不明白哪些样式表包括哪些，或者如果他们做。
如何在rails中将样式表匹配到特定视图？如何定义样式之间的层次结构，以便可以覆盖其他样式？

I don't understand which stylesheets includes which, or if they ever do. How do you match stylesheets to a specific view in rails? How do you define hierarchy between style so ones can override others?

匹配样式与视图的rails默认值是什么？我在应用程序中看不到任何 stylesheet_link_tag

What's the rails default for matching styles to views? I don't see any stylesheet_link_tag used in the app

推荐答案

最好的方法是在你的应用程序布局中设置一个命名的yield：

The best way would be to put a named yield in your application layout:

<%= yield :head %>

然后在视图中使用阻止的内容：

Then use a content for block in your view:

<% content_for :head do %>
   <%= stylesheet_link_tag :my_css -%>
<% end %>
