Thanks a bunch! You might want to tinker with your code-rendering on this site so that it doesn’t change your quotes to Unicode ones; or provide a download link as plain-text.

Incidentally, I had to change your test-case so that it tests a match on type, not Content-Type:

#ensure content-type is text/css
assert_match @response.headers['type'], “text/css”

Note: it’s possible to include a dynamic file as a stylesheet just like normal! Something like so:

< %= stylesheet_link_tag('/rcss/default', {:media => “all”})%>

You could of course map a route for this in routes.rb. I’ll leave that as an exercise for the reader. : )

Just to close out the comments with Monica - Science got a copy of Monica’s original application and it yielded to the Method. The code above still works and Monica is off and running!

Monica, what’s your routes.rb file look like? Do you have an entry for:


map.connect 'rcss/:rcssfile', :controller => 'rcss', :action => 'rcss'

Send us what you’ve got and hopefully we can work this out for you!

hi guys,
I get a problem all the time:

no route found to match “/rcss/default.css” with {:method=>:get}

It seems to be ’stupid’ but I’m not able to get the solution.
I’ve been looking at the routes.rb, trying to modify them,… but no way.
May you please give me some advice?

I’m looking forward to making it works…. thanks a lot in advance!

From Alexander May via email:

“I’ve created a extension to do syntax highlighting for rcss files in
ActiveState’s Komodo IDE (which admittedly has a smaller following
then Textmate) . http://codingfrenzy.alexpmay.com/2007/11/syntax-coloring-for-dynamic-css.html”

Thanks Alex! Science appreciates progress.

Using rails 1.2.3, had to adjust the route to…
map.connect ‘rcss/:rcssfile.:format’, :controller => ‘rcss’, :action => ‘rcss’

lastly, (this wasn't obvious to me at first) in your layout the link tag might look like this:

<%= stylesheet_link_tag '/rcss/style' %>

Thanks for the updated code linoj - greatly appreciated!

(Older versions of Rails didn’t consider a “.” as a separator, so I think my routes.rb code used to work but your code fixes this for new Rails versions.)
