Question

我试图在深层嵌套数组会话中推送新对象。如何将新数据推入这样的数组？我的Mongoose Schema是：

{
  month: String,
  sessionsCount: Number,
  dates: [{

    day: String,
    sessionsCount: Number,
    activeUsers: [{

      userId: String,
      userName: String,
      userEmail: String,
      lastActivityDate: Date,

      sessions: [{

        // some fields

      }]     

    }]

  }]
}

查询更新：

let query = { 
  "month": date.month, 
  "dates.day": date.day,
  "dates.activeUsers.userId": req.body.userId
};

let updateOptions = {
  $push: {"dates.activeUsers.sessions": data.dates.activeUsers.sessions}
}

Telemetry.update(query, updateOptions).then(session => res.json(session)).catch(error => res.json(error));

错误：

{
    "name": "MongoError",
    "message": "cannot use the part (dates of dates.activeUsers.sessions) to traverse the element ({dates: [ { day: \"22nd Jan\", _id: ObjectId('59520b5702bf00dc3482ceaf'), activeUsers: [ { userId: \"58f13c41114a70384a877b2e\", userName: \"Joel\", userEmail: \"jwasinger@thengan.com\", lastActivityDate: new Date(1485089983421), _id: ObjectId('59520b5702bf00dc3482ceb0'), sessions: [ { sessionStartDate: new Date(1496988833666), calendarShowChanged: 0, navigationDateChanged: 0, viewChanged: 0, orientationChanged: 0, multiboardChanged: 0, settingsChanged: 0, cardsRefreshed: 0, cardCreated: 0, cardRemoved: 0, cardEdited: 22, cardDropped: 0, cardOpened: 0, shortcutActivated: 0, sessionId: \"2\", appType: \"chromeExtension\", _id: ObjectId('59520b5702bf00dc3482ceb1') } ] } ], sessionsCount: 1 } ]})"
}

更新嵌套数组中的数据时出现同样的问题

如何在mongodb中推入深层嵌套的对象数组？
