無法在Mongodb中將對象插入到對象數組中

Question

我一直在試圖將某些元素放入此代碼中。 （請忽略愚蠢的虛擬數據）

{ 
"Order_Number": "1", 
"Status": "Pending", 
"Customer":{ 
    "First_Name": "Juan", 
    "Second_Name": "De La Cruz", 
    "Email": "juandelacruz@gmail.com", 
    "contact": "0923275937" 
      }, 
"Shipping_Address": "291,Ominous Building, Quezon City, Philippines", 
"Billing_Address": "IOU, Iowa, USA", 
"Weight": "200 lbs.", 
"Description": "Joots", 
"Tracking Information": { 
    "Tracking Number": "000000001", 
    "Shipping History": { 
     "Shipping Transactions": [ 
      { 
       "Date Received": "10/1/2013", 
       "Date Released": "10/10/2013", 
       "Source": "Center of the earth", 
       "Control Number": "100010001" 
      }, 
      { 
       "Date Received": "10/2/2013", 
       "Date Released": "10/12/2013", 
       "Source": "Center of Venus", 
       "Control Number": "100010002" 
      }, 
      { 
       "Date Received": "10/3/2013", 
       "Date Released": "10/13/2013", 
       "Source": "San Francisco", 
       "Control Number": "100010003" 
      } 
     ] 
    } 
} 
} 

現在，我一直在試圖將這些元素轉換爲「Shipping Transactions」。

{ 

     "Date Received": "10/2/2013", 
     "Date Released": "10/11/2013", 
     "Source": "Center of Mars", 
     "Control Number": "100010005" 
} 

我試過做推動，但它甚至沒有將自己添加到數組中。

{$push:{"Tracking Information":{"Shipping History":{"Shipping Transactions": 
    [{"Date Received": "10/4/2013", 
    "Date Released": "10/11/2013", 
    "Source": "Center of Mars", 
    "Control Number": "100010005"}] 
} 

可能這段代碼有缺陷或我做錯了什麼？我只使用MongoDb的web shell btw。

這應做到：

{ 
    $push:{"Tracking Information.Shipping History.Shipping Transactions": {"Date Received": "10/4/2013", 
    "Date Released": "10/11/2013", 
    "Source": "Center of Mars", 
    "Control Number": "100010005"}} 
} 

這就是所謂的dot notation。真的很有用。
