Using register_template_handler to serve CSS files (Making A


I wanted to be able to use some Rails code inside CSS files, so I set up
a controller (StylesController) to serve CSS files that reside inside
the controller’s view folder when the browser requests

So in the controller I just define empty actions with the names I want
my style sheets in (ie: def cooleffects end - that would respond to

And in views/styles I have cooleffects.css

Then, I tried the following (both inside the controller, and in a
plugin’s init.rb):

ActionView::Base.register_template_handler ‘css’, ActionView::Base

Which doesn’t seem to have any effect, because Rails throws an error on
the CSS file (no matter if I comment the line above):

|No rhtml, rxml, or delegate template found for |

So, how can I make ActionView handle CSS files as if they were RHTML

Do you know RCSS?
It lets you use Erb inside css stylesheets.

Note: I’ve experienced some problems when using RCSS on a shared server
(Dreamhost). I wonder if it’s related to RCSS resource need:it has to
translate the RCSS file into a CSS one. What happened is that the page
would sometimes render without any styling, as when you remove all the
stylesheed. Refreshing the page would have display correctly.


Thanks Alain, it looks very interesting, specially the server-side
constants, which are something that I was looking to implement using
plain old erb code.

However, since you mention some problems with it, I’ll just keep an eye
on it for future usage. Right now, I went with this:

    tpl = ''"#{RAILS_ROOT}/app/views/styles/#{params['cssfile']}")

do |css|
while line = css.gets
tpl += line
render_template tpl
