database - 如何将新对象添加到mongo中的现有数据

Question

我的 table 上有这样一个文档UserCollection:

{
  "FirstName": "Mohammad",
  "LastName": "Waheed", 
}

我想向其中添加另一个数组对象，我该怎么做呢？

  "PhoneNumbers":[  //this object is not present in the table
        {
          "number": NumberInt(8332045764) 
        },
        {
          "number": NumberInt(1234567890) 
        } 
     ] 

我的预期结果是这样的:

{
  "FirstName": "Mohammad",
  "LastName": "Waheed",
  "PhoneNumbers":[  
        {
          "number": NumberInt(8332045764) 
        },
        {
          "number": NumberInt(1234567890) //when i call this method again it should store like this
        } 
     ] 
}

这是我尝试过的: 1.只得到那条记录 2. $number有电话号码的数据

return $db->update(array('$set' => array("PhoneNumbers.$.number" => $number))); 

Answer 1

您可以使用 $push 命令将多个数字添加到列表中

   model.update({'FirstName':'Mohammad'}, {$push:{PhoneNumbers: NumberInt(1234567890)}}, function (err, updatedModelObj) {
if (err) {
   console.log(err);

}
callback(updatedModelObj);

})
