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).
