Rails core - Aug 2012 - Suggestion; a mechanism to specify asset path for controller (or specified actions)

Good day!

Rails have *layout* method that allows you to specify a layout for 
controller or some it actions. So we can specify a template (HTML) for each 
action.

But not only HTML specifies page''s design (view) but CSS and JS, also. 
Asset, in Rails terms.

But can specify an asset for each action (by standard Rails'' mechanism,
without dancing-with-bells :))? If not, I think it''s a good idea to
have it
- to have a possibillity to change the whole page''s design.

Thanx.

Couldn''t this be simply achieved by using a layout which uses different
CSS
files?

So

Layout1 loads CSS/desktop.css
Layout2 loads CSS/mobile.css

For example

What about images? Ok, I said: it''s possible. Is it possible with
relax?
For layouts - possible. But for assets?

could you provide a specific example when you actually need separate assets?

You could easily do theming with scss:

<pre>$theme: ''winter'';
@if ''halloween'' == $theme {
  body { background: #000; }
  a#logo { background: image-url(''logo_jason.png'') ;}
}
@else {
  body { background: #e9e9e9; }
  a#logo { background: image-url(''logo_default.png'') ;}
}
header {
  background: image-url(''themes/#{$theme}/header.jpg'') center
top no-repeat;
}</pre>

or something like that.
