Hi List! Following http://rcss.rubyforge.org/files/README.html, I''m trying to get RCSS to work with Rails. The rcss command itself works fine, but when trying to access http://localhost:3000/rcss/test.css I always get "Unknown action - No action responded to test.css", which I don''t understand since the route and controller are in place. Anyway, hopefully this is just a newbie''s lacking knowledge of Rails :-) Whatever pointers you might have would be greatly appreciated... Best regards, Raphael Schmid -- Posted via http://www.ruby-forum.com/.
Hi again,
after some fiddling around with initial help from rainmkr on IRC, I''ve
come to the conclusion that there must be something wrong with the
render() call in the RcssController as shown at
http://rcss.rubyforge.org/files/README.html.
The type is set to ''rcss'', but the README doesn''t
talk about any piece
of code that''d tell Rails to process *.rcss files with the
/usr/bin/rcss
command. Does anybody know if that code exists anywhere, or could give
me a pointer towards creation of such code?
Thanks and best regards,
Raphael Schmid

The response you are getting "Unknown action - No action responded to test.css" suggests that your routes.rb is not set-up properly. Could you provide your routes.rb? It would help to find the problem. -- ?ukasz Piestrzeniewicz http://ragnarson.blogspot.com
Czezch ?ukasz,
thanks for your reply! My complete routes.rb looks like this right now:
ActionController::Routing::Routes.draw do |map|
map.connect '''', :controller => "login"
# map.connect ''stylesheets/:rcss'', :controller =>
''rcss''
map.connect '':controller/service.wsdl'', :action =>
''wsdl''
map.connect '':controller/:action/:id''
# map.connect ''rcss/:rcss'', :controller =>
''rcss''
map.rcss ''rcss/:rcss'', :controller =>
''rcss''
# map.connect ''stylesheets/:rcss'', :controller =>
''rcss'', :action =>
''render_rcss''
end
As you can see, I''ve been playing around with the routes quite a bit,
to no avail. Tell me if there is anything else that can be done.
Best regards,
Raphael

Tell me if there is anything else that can be done.I have marked important part. The line map.connect '':controller/:action/:id'' describes the most generic route. It caches everything what has not been caught yet. If you put another rule below this line it will not be reached at all. My suggestion is to use following setup and try again: ActionController::Routing::Routes.draw do |map| map.connect '''', :controller => "login" map.connect ''rcss/:rcss'', :controller => ''rcss'', :action => ''render_rcss'' map.connect '':controller/service.wsdl'', :action => ''wsdl'' map.connect '':controller/:action/:id'' map.rcss ''rcss/:rcss'', :controller => ''rcss'' end As a sidenote: in Rcss subversion repository you will find engine-based version or Rcss. It is tested and working but it lacks documentation. Contact me if you are interested. -- ?ukasz Piestrzeniewicz http://ragnarson.blogspot.com

If possible, I''d like to try and not get any Engine whatsoever into my application. Just doesn''t feel right. A plugin, like Markaby, would be great though :-) (is there something about creating plugins -- I''d give it a shot) Thanks and best regards, Raphael -- Posted via http://www.ruby-forum.com/.

Controller is there so that you can access your rcss file using /rcss/xxx.css notation. If you rely on Rails defaults it should be possible to: 1. Add a line ''require "rcss"'' to environment.rb 2. Generate a dummy controller (./script/generate controller rcss) 3. Put test file in app/views/rcss/test.rcss 4. Access it by http://localhost:3000/rcss/test (note, that there is no .css at the end). Now, as RcssController does contain some meaningful code and is identical (or similar) on all deployments it would be nice to make it part of distribution. And right now the only clean way of providing controllers to existing applications is to create an Engine. -- ?ukasz Piestrzeniewicz http://ragnarson.blogspot.com

For instance, I just tried this out: /vendor/plugins/test_plugin/ |- lib |- test_controller.rb which contains: class TestController < ApplicationController def index; render :text => ''Get your ass to Mars!''; end end This works from the url http://localhost:3000/test/index, so I don''t think that in this case RCSS *needs* to be an engine. That said, you still can''t load views, routes, migrations, static web assets (images, stylesheets, javascripts) or plenty of other stuff from plugins, nor can you easily override only a small part of a controller included in this way (without using subclassing, but that might make sense in some circumstances, to be fair).

A plugin, like Markaby, would be great though :-)I''m aware that some people think that engines ''smell bad'' (and of course everyone has a right to their opinion, however they have derived it), but until Rails supports loading those types of files from arbitrary locations, the Engines plugin will strive to fill that gap for those people (me, certainly) who find it useful or even necessary to isolate and/or share parts of their applications using plugin-style entities. The emphasis there is on ''plugin''. If you think that to any extent that type of behaviour might be useful and should be provided by the Rails ''out of the box'', send a message to rails-core asking them to look into it. Nothing would make me happier; reflecting the Rails philosophy, it would mean less code for *me* to write ;-) james -- * J * ~
Hi again,
thanks to ?ukasz'' patience with me, I got it working now.
The secret is to use Ruby 1.8.4 -- my Ubuntu install had
1.8.3, d''oh.
One more question though: if I wanted to share a set of
variables between a couple of RCSS templates, where would
they be best put?
James:
I do think the RCSS behaviour should be available in RoR
out of the box. Personally, I don''t need anything else
that Engines provides. You will probably have had your
fair share of discussion about it on rails-core and the
Core Devs will have their reasons for not including it...
for me it''s just a gut feeling that I''d better not use it.
In no way did I want to rate it in any way, be it positively
or negatively.
However, since there''s RJS I''m much hoping for RCSS to get
it. It definitely does make some things easier.
Best regards,
Raphael

I''ve entirely switched to Markaby, so having ERB in the RCSS files would have introduced kind of an inconsistency... but if Markaby has the helper methods/variables available, they''re surely not dependant on ERB?

On the other hand it''s an Engine... ;)Why drop ERB? That seemed like the whole point of doing RCSS. Personally I was planning to use it only for ERB and don''t care at all about SSI. Mostly I want to use RCSS for customizing CSS based on values stored in models. I was about to write it for myself when I happily found it already existed, but it seems that you are taking it in a direction that isn''t as useful as I''d hoped. I may have to just grab the code and modify it for my own purposes, but I''d be interested in hearing why ERB isn''t being supported anymore.

I''m going to need that functionality anyway, so I might as well. I''m not interested in the server-side includes, but defintely want an RCSS plugin that uses ERB.
