undefined method `table_name'

Hi

I'm relative new to RoR - but I'm having a problem with some model relationships that I thought should have worked. Hope someone can help.

The code...

MODELS:

class Delivery < ActiveRecord::Base belongs_to :vehicle end

class Vehicle < ActiveRecord::Base has_many :deliveries

def self.find_all_active    Vehicle.find(:all, :order => 'name', :conditions => ['is_active = ?', true]) end

end

CONTROLLER: @vehicles = Vehicle.find_all_active

VIEW: <%= vehicle.deliveries.length %>

The error... undefined method `table_name' for Delivery:Class

Notes... The problem seems to be the class method find_all_active. I tested the equivalent calls in the console and they work fine - so why not when the application is running?

Any comments appreciated

Thanks
