MongoDB |將嵌入文件插入文件時出現問題

我正在嘗試以嵌套格式插入數據。

我的模型片段（還有很多很多）：

class LifetimeMode(db.EmbeddedDocument):
   meta = {'collection': 'lifetime_mode'}
   career = db.EmbeddedDocumentField(GameModeData)
   war = db.EmbeddedDocumentField(GameModeData)
   sd = db.EmbeddedDocumentField(GameModeData)
   dom = db.EmbeddedDocumentField(GameModeData)

class LifetimeData(db.EmbeddedDocument):
   meta = {'collection': 'lifetime_data'}
   mode = db.EmbeddedDocumentField(LifetimeMode)

class UserData(db.EmbeddedDocument):
   meta = {'collection': 'user_data'}
   timestamp = db.DateTimeField(default=datetime.utcnow)
   type = db.StringField()
   level = db.IntField()
   lifetime = db.EmbeddedDocumentField(LifetimeData)

class User(db.Document):
   meta = {'collection': 'user'}
   public_id = db.UUIDField()
   gamer_id = db.StringField()
   user_data = db.EmbeddedDocumentField(UserData)

當我嘗試使用虛擬數據創建數據庫時，我遇到了無法解決的問題。我從外部 API 獲取數據。

lt_mode_data = data['lifetime']['mode'] # << This is the API returned data
for mode, mode_data in lt_mode_data.items():
   game_mode_data = GameModeData()
   lifetime_mode = LifetimeMode()
   json_data = json.dumps(mode_data['properties'])
   lifetime_mode[mode] = game_mode_data.from_json(json_data)

問題是只添加了最終模式，好像每個模式數據都被添加但隨後被下一個模式覆蓋。

有任何想法嗎？

為了解決這個問題，我將程式碼更改為以下內容：

lt_mode_data = data['lifetime']['mode']
   mode_dict = {}
   game_mode_data = GameModeData()
   lifetime_mode = LifetimeMode()
   for index, (mode, mode_data) in enumerate(lt_mode_data.items()):
       mode_dict[mode] = mode_data['properties']
   lifetime_mode = lifetime_mode.from_json(game_mode_data.from_json(json.dumps(mode_dict)).to_json())
