Ruby inside stylesheet

If you're talking about dynamically changing colors in your running application, then I would suggest separating those parts into theme CSS files that you selectively include in your layout based on a user's preference or something.

Hello,

I'm not sure if this will work with CSS's (I have not tryied it yet) but I did this with a JavaScript file:

In the "app/views/layouts/application.rhtml" file:

<% @myVar = 20 %> <!-- This variable could come from a controller. //-->
<%= javascript_include_tag 'test.js.rhtml?myVar='.@myVar.to_s %>

In the "public/javascripts/test.js.rhtml" file:

<%
  begin
    myVar = params[:myVar].to_s # In PHP I use this $_GET['myVar'];
  rescue Exception => exc
    myVar = exc.to_s
  end
%>
alert("Hello World <%= myVar %>");

Ok, here everything so far so good, all the Ruby sentences are working (you will notice it because of the "begin...rescue") and most of the Rails issues too, even I could get information from a model without any problem.

However there is a little problem with the "parms" variable because it's not working, I'm trying to find out what it's this problem.

For the CSS solution should be something like:

In the "app/views/layouts/application.rhtml" file:

<% @myVar = 20 %> <!-- This variable could come from a controller. //-->
<%= stylesheet_link_tag 'test.css.rhtml?myVar='.@myVar.to_s, :media=>'all' %>

Or something like that!

I hope it helps you.

Thanks.
