Rails - Apr 2010 - Developing plugins

Hi *,
I''m trying to develop a plugin, but I''m having some problems
integrating it in Rails.

The first problem is when I need to load the environment: I would like the
plugin to be installable in the classic way (under /vendor) and as a gem. Right
now I''m using something like

require File.join( File.dirname( __FILE__ ), ''..'',
''..'', ''..'', ''..'',
''config'', ''environment'' )

but of course I don''t think it will work as a gem. How can I require
the env to have it work in both ways ?

The other problem I''m facing is when I try to have the plugin to
include itself inside ActionController (an example can be login_required of
restful authentication).
This is what I''m trying to do:

$:.unshift File.expand_path( File.dirname( __FILE__ ) )
require ''charon/class_methods''

module Charon
  #some stuff
end

ActionController::Base.send :include, Charon::CharonClassMethods

and in charon/class_methods

module Charon
  
  module CharonClassMethods

    def self.included base
      base.send :extend, Charon::CharonClassMethods::ClassMethods
    end

    module ClassMethods

      def authentication_url
        # implementation
      end

    end

  end

end

What I don''t understand where I should include the main application,
how to load rails and when (I can require ActionController in the first file but
it doesn''t feel right ...) and what to put inside hte various
initialization files.
If someone knows of a plugin with specs that I can copy I would be very glad.
It''s not that I don''t find them, but every plugin I find does
things in a different way, so it''s not entirely clear which way is the
best one.

TIA,
  ngw

Well the rails framework (and constituent parts) will already have
been loaded at the point  your init.rb is run. requiring config/
environment again at that point probably doesn''t do anything at all.
For a gem plugin if my memory is correct you''ll want to ensure rails/
init.rb exists (and do your rails specific setup in there).
