Suppose the following data schema: Usage ====== client_id resource type amount Billing ====== client_id usage_resource usage_type rate In this example, suppose I have multiple resources, each of which can be used in many ways. For example, one resource is a widget . Widgets can be foo ed and they can be bar ed. Gizmo s can also be foo ed and bar ed. These usage types are billed at different rates, possibly even different rates for different clients. Each occurence of a usage (of a resource) is recorded in the Usage table.

I have two models: (Albums and Product) 1) Inside Models Inside album.rb: class Album < ActiveRecord::Base attr_accessible :name has_many :products end Inside product.rb: class Product < ActiveRecord::Base attr_accessible :img, :name, :price, :quantity belongs_to :album end 2) Using " rails console ", how can I set the associations (so I can use "<%= Product.first.album.name %>")? e.g. a = Album.create( :name => "My Album" ) p = Product.create( :name => "Shampoo X" ) # what's next? how can i set the album and the product together?
