Rails - May 2005 - Deleting from a 'has_many' collection doesn't set the foreign key to NULL

Hi all, 

I have an Active Record problem. Having this classes declaration. 

class Sale < ActiveRecord::Base
 has_many :sale_line_items, :class_name ''SaleLineItem'' 

 ... 

end 

class SaleLineItem < ActiveRecord::Base
 ... 

end 

When I try to delete an item in a Sale class method from sale_line_items 
(sale_line_items.delete(li)), it extracts ''li'' from the
container as
expected, but it doesn''t set the foreign_key
''sale_id'' to NULL as especified
in the documentation. 

please, could someone tell me if i misunderstood something (my english is 
poor), or if it is a BUG???

Does SaleLineItem belongs_to :sale?  AR needs to know there''s a foreign
key in sale_line_items linking it to the sale.  The belongs_to keyword
is what sets this up.

Sorry for my delay to reply, 

I''ve done what you say (I really thougth it was the solution),
SaleLineItems
belongs_to Sale now, but I get the same problem. May this be a BUG??.
