Mongodb嵌套插入

Question

我的數據如下，現在favoriteapi將有關鍵/值記錄進出。

我如何將數據插入到該嵌套元素

{ 

"firstname": "ram5656", 
"lastname": "rahul", 
"email": "ram@ram.com", 
"password": "encrypt", 
"favoriteapi" : [ 
    { 
     "api_id" : "function", 
     "api_name" : "enterprise" 
    }, 
    { 
     "api_id" : "data_subject_category", 
     "api_name" : "address" 
    }, 
    { 
     "api_id" : "data_subject", 
     "api_name" : "address" 
    } 
], 
"is_active": true, 
"create_ts": "2016-05-18T00:00:00.000Z", 
"create_by": "ram@ram.com", 
"update_ts": "2016-05-18T06:00:00.000Z", 
"update_by": "ram@ram.com", 
"lastlogin": "2016-05-01T00:00:00.000Z" 

}

我想這

var updatedocument =  
    { 
     "api_id" : "sanket", 
     "api_name" : "sanket" 
    } 

user.favoriteapi.insert(updatedocument, options); 

，但沒有運氣。

我應該使用upsert嗎？

你必須做你的用戶文檔的update，並指定要$push一個新的子文件到favouriteapi陣列。

var updatedocument = { 
    "api_id" : "sanket", 
    "api_name" : "sanket" 
}; 

db.user.update(
    {"email": "ram@ram.com"}, 
    {$push: { 
     "favouriteapi" : updatedocument 
    } 
    } 
);
