the best way to have separate stylesheets for different actions in Rails
I have one app layout that includes app wide css stylesheets and js files, but some controller's actions need a开发者_高级运维dditional stylesheets that is used only for these action s view? What is the best way to include them?
If your app is typically something like:
<html>
<head>
<%= stylesheet_link_tag 'application' -%>
<%= javascript_include_tag 'yui', 'application' -%>
</head>
<body>
<%= yield -%>
</body>
</html>
You can add other yield blocks wherever you like, named whatever you want. Typically I used this to include page-specific functionality wherever I like, even to the degree that maybe partials supply their own.
# layouts/application.html.erb
<html>
<head>
<%= stylesheet_link_tag 'application' -%>
<%= javascript_include_tag 'yui', 'application' -%>
<%= yield :head -%>
</head>
<body>
<%= yield -%>
</body>
</html>
# views/profiles/show.html.erb
<%= title("#{@user.name}'s Profile") -%>
<% content_for :head do -%>
<%= javascript_include_tag 'gallery' %>
<% end %>
<%= render @user.photos %>
So on and so forth...
For the javascript, one way to deal with this is using a <%= yield :javascript %> inside your the ... tag in your layout file. Then in your view code, you can use a <% content_for :javascript do %> ...put your javascript here ... <% end %>
This way, your javascript and your html erb code live in the same location.
Javascript that is used throughout the sight can be placed in a global file.
