どのように私はBusiness.Children.Childrenに別の文書を挿入することができます。（株ソフトウェア）.Children

Answer 1

は値をプッシュする位置演算子を使用します。

https://docs.mongodb.com/manual/reference/operator/update/positional/

db.collectioname.update(
    { 
    "_id" : ObjectId("576bddaa08b8f7dc20000033"), 
    "Children._id" : ObjectId("57715e0608b8f7441b00002d") 
    }, 
    { 
    $push: 
    {"Children.$.Children": 
    { 
     "Name" : "Business School", 
      "URLName" : "Business-School", 
      "Image" : "http://www.small-business-website.net/wp-content/uploads/2016/04/How-to-achieve-a-successful-business-sale-128x128.jpg", 
      "Description" : "Everything about Business Schools", 
      "NoForums" : 0, 
      "NoTopics" : 0, 
      "NoComments" : 0, 
      "NoUsers" : 0 
     } 
    } 
    } 
    ) 

注：モンゴはupdate.Itにネストされた文書を許可しないしない用心は既知の問題です。単一のレベルのみが許可されます。 https://jira.mongodb.org/browse/SERVER-831
