thanks.

i want to know if i can test these associations in a standalone rb 
file(without webrick), i tried and it didn''t work.

i use:

 require ''rubygems''
 require_gem ''activerecord''

 ActiveRecord::Base.establish_connection(
   :adapter => ''mysql'',
    :socket=>''/var/run/mysqld/mysqld.sock'',
   :host => ''localhost'',
   :username => ''root'',
   :password => '''',
   :database => ''db1''
 )

 class Order < ActiveRecord::Base
	has_one :Item
 end
 class Item < ActiveRecord::Base
	belongs_to :Order
 end

...
order.item =item
...


it told me ''item='' not defined.

must i test under the support of webrick or script/console?

Hey Chen, I would recommend going through the following at:

**http://developer.apple.com/tools/rubyonrails.html

BTW, it doesn''t cover ''has_one'' but it uses the
''has_many''.
In addition to that it covers the following:

- belongs_to
- migrations

Peace,

-Conrad

That''s what script/console is for - it''s extremely useful.
