如何在版面之外的erb中包含CSS或JavaScript？ [英] How to include a css or javascript in an erb that is outside the layout?
问题描述
对不起，我正在写我的第一个rails应用程序。
Sorry for the slightly noobish question, as I am writing my first rails app.
我对布局视图有所了解，但是如果您正在使用它们，有什么办法可以包含特定于视图的js或css文件？例如，我有 layouts / products.html.erb ，对于 products / edit.html.erb 我想要 products_edit.css ，但我不希望所有产品视图都使用该CSS，最佳做法是什么？
I get the idea of the layout view, but if you are using them, is there any way to include a view specific js or css file? For example, I have layouts/products.html.erb, and for products/edit.html.erb I want products_edit.css, but I don't want that css for all product views, what is the best practice to accomplish that?
推荐答案
如果您有通用的edit.css文件，建议您在布局中使用if
If you have a generic edit.css file, I would suggest an if in your layout
<%= stylesheet_link_tag 'edit' if params[:action] == 'edit' %>
否则，您可以使用 content_for 的收益为 code>将其他标签添加到头部。
Otherwise you can use content_for with a yield to add additional tags into the head.
layout.html.erb
<head>
...
<%= yield(:header) if @content_for_header %>
</head>
products / edit.html.erb
<% content_for :header do -%>
<%= stylesheet_link_tag 'edit_product' %>
<% end -%>
