To use app/views/stylesheets/mystyle.rcss as an ERB template, follow these steps:
script/generate stylesheets
In config/routes.rb
<![CDATA[
map.connect 'stylesheets/:rcss', :controller => 'stylesheets', :action => 'rcss'
]]>
in app/helpers/application_helper.rb
<![CDATA[
module ApplicationHelper
def rcss_path(name)
file_base = name.gsub(/\.css$/i, '')
return "#{RAILS_ROOT}/app/views/stylesheets/#{file_base}.rcss"
end
def stylesheet_tag(name)
date = File.mtime(rcss_path(name)).to_i
return "<link type=\"text/css\" rel=\"stylesheet\" href=\"/stylesheets/#{name}.css?#{date}\" />"
end
end
]]>
In app/controllers/stylesheets_controller.rb
<![CDATA[
class StylesheetsController < ApplicationController
include ApplicationHelper
layout nil
session :off
def rcss
if name = params[:id]
file_path = rcss_path(name)
expires_in 3.days
render(:file => file_path, :content_type => "text/css")
else
render(:nothing => true, :status => 404)
end
end
end
]]>
in app/views/stylesheets/mystyle.rcss
html,body{
margin:0;
padding:0;
color: <%=@color%> /*example dynamic style*/
}
Then in your .rhtml template:
<%= stylesheet_tag "mystyle" %>
