{ $t: “”, $v: “”} structure in MongoDB collections using pymongo

问题

I'm using pymongo libraries to upload my data into documentDB (it accepts MongoDB libraries). My json data objects (read using the json library from a json file) before sending them to my documentDB collection are in the format of (a portion of the data):

...
{
"id": [
    "{}",
    "i"
  ]
}
...

However, in the database they are stored like:

...
{
  "id": {
    "$t": 4,
    "$v": [
      {
        "$t": 2,
        "$v": "{}"
      },
      {
        "$t": 2,
        "$v": "i"
      }
    ]
  }
}
...

My python code that inserts data into MongoDB is

client = MongoClient("url")
self.__db = client["database"]
self.__db["collection"].insert_one(data)

For debugging purposes I added this line right before insert_one() statement

for k, v in data.items():
  print(k, v)

and here is the output on the console:

.. 
id ['{}', 'i'] 
..

Is there any additional parameter that I need to set on pymongo to save data as is? When I read data from the MongoDB using pymongo it handles $t, $v conversions but my data readers are not in python and don't do the conversion automatically

Update I switched to DocumentDb python library. It works just fine. I just needed to spend a couple of hours creating a new db interface for it in my app.
