[Rails] Active Record: subclassing a model

Hi there,

I have a model

class Account < ActiveRecord::Base
  has_many: projects

The accounts table holds company information so as I created another
model to represent project partners thus:

class Partner < Account
  has_and_belongs_to_many :projects

#project.account pulls up the project owner and #project.partners pulls
up all partners, including the owner.

Now, this all seems to work fine but every now and then I get the
following error message:

(eval):1:in `alias_method'': undefined method
`destroy_without_callbacks''
for class `Partner''

....trace.....

This error occured while loading the following files:
   ./script/../config/../app/controllers/application.rb
   login_system.rb
   user.rb
   account.rb
   project.rb
   partner.rb

I can''t figure out how to correct this. Any ideas?

Regards

Adam Groves
