I hate having to ask this but my eyeballs are spinning and I seem to be getting some odd behavior.
a bit of the schema:
create_table "orders", :force => true do |t| t.column "billing_address_id", :integer ... end
# single table inheritance here... AddressBilling & AddressShipping create_table "addresses", :force => true do |t t.column "type", :string, :limit => 20 .... end
which of these pairs is correct?
class Order < ActiveRecord::Base has_one :billing_address, :class_name => "AddressBilling" end
class AddressBilling < Address belongs_to :order end
------- OR ----------------
class Order < ActiveRecord::Base belongs_to :billing_address, :class_name => "AddressBilling" end
class AddressBilling < Address has_one :order end
I thought the first was the correct but I'm a noob and neither seem to be working as I'd expect.
When I do this in the controller: @orders = Order.find(:all)
then in the view: <% @orders.each do |order| %> <tr><td><%= order.billing_address_id %></td></tr> <% end %>
that works fine but then if I do this: <% @orders.each do |order| %> <tr><td><%= order.billing_address.id %></td></tr> <% end %>
I get an error about billing address being a nil object? Yes the billing address is there with the correct id.
seems odd to me... any help greatly appreciated and thanks in advance! Tim
