How to include a css or javascript in an erb that is outside the layout?
Sorry for the slightly noobish question, as I am writing my first rails app.
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?
Answer
If you have a generic edit.css file, I would suggest an if in your layout
<%= stylesheet_link_tag 'edit' if params[:action] == 'edit' %>
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 -%>
