mongoid继承问题
我有一个像这样的模型
class Canvas
include Mongoid::Document
field :name
referenced_in :hero
end
class Browser < Canvas
field :version, :type => Integer
end
class Hero
include Mongoid::Document
field :name
references_many :canvases
end
How can I build Brower Object引用自Hero对象。
我想做的就是
h = Hero.create!({:name => 'Aston'})
h.browsers.build
但是它给了我一个错误
undefined method `browsers' for #<Hero _id: 4d92c8fc1426960fff000005, name: "Aston">
我错过了什么吗？
谢谢
