My app calls for the use of :foreign_key into a model that it should
be nested with. I can't get the routes set up the way I want them.
Here is an example:
People buy and sell from each other. The purchase or sale is recorded
in an Order model.
class Person < ActiveRecord::Base
has_many :purchases, :class_name => 'Order', :foreign_key =>
has_many :sales, :class_name => 'Order', :foreign_key => 'seller_id'
class Order < ActiveRecord::Base
belongs_to :seller, :class_name => "Person"
belongs_to :buyer, :class_name => "Person"
The routes to display a list of purchases or sales is /people/1/orders?
buyer_id=1 and /people/1/orders?seller_id=1 respectively. The route
table has this entry:
map.resources :people, :has_many => :orders
The Orders controller ferrets out which parameter was sent in and does
the appropriate search before rendering the index. (At this point, I
feel all sticky and want to take a shower.)
I'd really like to have nested routes such as /people/1/purchases and /
people/1/sales. So I'm kind of surprised I can't do this in Rails
map.resources :people do |people|
people.resource :sales, :as => 'orders'
people.resource :purchases, :as => 'orders'
... or something similar to give me the correct nested routes.
Maybe you have a better way? Maybe I'm missing something.
