Rails - Feb 2006 - dynamically generating a controller and appropriate routing

I''m working on a library similar to acts_as_taggable. I''d like
it to be a
simple, one file drop-in: i.e., put my_library.rb into RAILSROOT/lib/ and
have everything work. However, the library requires a controller to render
some stuff, so I need to be able to create the controller class, set the
routing, and extend the controller at run-time from within my_library.rb.

I have code that creates and extends the controller properly; I''ve
tested
that it works via the console. However, the code that I have in place to add
a route to connect a url to the extended methods in the controller
doesn''t
seem to take effect. When testing via the webrick server, I get an
unrecognized route error.

What I have in my_library.rb is something like the following:

say I''ve generated the following controller from within my_library.rb:

class ASampleController < ActionController::Base
  def some_thing
    render_text "hello world!"
  end
end

and also from within my_library.rb I have the following code to add a route:

ActionController::Routing::Routes.connect
''/show/:model_name/:id'',
:controller => ''ASampleController'', :action =>
:model_name.to_s

However, the route doesn''t seem to be put in place, or even recognized.
If I
examine ActionController::Routing::Routes from within the console, my route
does not show up. When I attempt to browse to the appropriate url, I get the
following in log/development.log:

   
/opt/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/routing.rb:469:in
`recognition_failed''
   
/opt/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/routing.rb:459:in
`recognize!''
    /opt/local/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/dispatcher.rb:38:in
`dispatch

Does anyone have any suggestions as to how I could go about getting the
route recognized? Any help is greatly appreciated.

I sent a query on a similar issue awhile ago (
http://wrath.rubyonrails.org/pipermail/rails/2006-February/016706.html )

The Restafarian plugin includes a module that seems to add a method to add
routes at runtime:

ActionController::Routing::RouteSet.send :include, RestfulRoutes


So you could probably include a method to add a named_route as above and
then call it in init.rb.  There is however a reload method that forces a
re-read of routes.rb  defined in routing.rb in the rails core so I am
guessing that it gets called at least once...  It would be fantastic if
someone could confirm the behavior of this reload method in routes.
