小编ros*_*ose的帖子

我有两个型号:(专辑和产品)

1)内部模型

在album.rb里面:

class Album < ActiveRecord::Base
  attr_accessible :name
  has_many :products
end

内部product.rb:

class Product < ActiveRecord::Base
  attr_accessible :img, :name, :price, :quantity
  belongs_to :album
end

2)使用" rails console ",如何设置关联(所以我可以使用"<%= Product.first.album.name%>")？

例如

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?
