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__ ) )
ActionController::Base.send :include, Charon::CharonClassMethods
and in charon/class_methods
def self.included base
base.send :extend, Charon::CharonClassMethods::ClassMethods
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.
