Mongoid：顯示與embeded_in對象整個MongoDB的對象在Rails的控制檯

Question

class Parent 
    include Mongoid::Document 
    embeds_many :children 
    field :title 
end 

class Child 
    include Mongoid::Document 
    embedded_in :parent 
    field :name 
end 

Rails的控制檯

parent = Parent.new(:title => "Hello World") 
parent.children << Child.new(:name => "Pedro") 
parent 
#=> #<Parent _id: 4e2330286254cc0e7d000007, _type: nil, title: "Hellow World"> 

所以，我怎麼能檢查在Rails的控制檯整個對象，直到孩子在我的parent包埋就像我能做到這一點在mogodb控制檯

{ 
    "_id" : ObjectId("4e2330286254cc0e7d000007"), 
    "title": "Hello World", 
    "children" : [ 
    { 
     "_id" : ObjectId("4d3ed089fb60ab534684b7e0"), 
     "name" : "Pedro" 
    } 
    ] 
}

你可以嘗試檢查你的Mongoid對象的屬性，像這樣：

parent.attributes.inspect
