If you're like me and use CE as a plugin, and want customize CE
without modifying the original source, there's a pretty simple way
with the "require_dependency" statement. This method works for both
Models and Controllers. Just create a blank Model or Controller file,
and call it like this:
require_dependency "#{RAILS_ROOT}/vendor/plugins/community_engine/
app/models/user.rb"
class User < ActiveRecord::Base
...
(override only the methods you want)
...
end
The reason I use this for Controllers (and not only Models) instead of
just copying the *_controller.rb file, is because the Controller is
loaded twice and you'll end up getting a "NoMethodError (undefined
method `controller_name' for nil:NilClass):" error message on
production. This is due to filters being loaded twice when you
duplicate the controller. To put it simply, the suggested way of
overriding a Controller via copying the file WILL give you problems!
