Javascript 如何在mongodb on应用程序中同时删除使用相同id的两个不同集合中的文档

我试图同时删除两个不同集合中使用相同id的文档。有什么可能性吗

用户集合：

{
    "_id" : ObjectId("5a310315f685dd5038fecaaa"),
    "userId" : 3,
    "accountId" : 1,
    "userType" : "DRIVER",
    "firstName" : "Karthi",
    "lastName" : "keyan",
    "email" : "karthikeyan.a1@gmail.com",
    "password" : "$2a$12$KFYc6riMnqTuzXhR0ssKZQmejAU4RF8FthAIQD4sgOUcALesp7DaJxK",
    "phone" : "xyz",
    "updatedAt" : ISODate("2017-12-13T10:38:13.492Z"),
    "createdAt" : ISODate("2017-12-13T10:38:13.492Z"),
    "__v" : 0
}

{
    "_id" : ObjectId("5a310315f685dd5038fecaab"),
    "workerId" : 1,
    "accountId" : 1,
    "name" : "Karthikeyan",
    "email" : "karthikeyan.a1@gmail.com",
    "mobile" : "xyz",
    "type" : "DRIVER",
    "joinDate" : ISODate("2017-12-13T10:38:13.070Z"),
    "assignedVehicleId" : "23423231",
    "licenseNumber" : "TN2506",
    "createdBy" : "1",
    "createdDate" : ISODate("2017-12-13T10:38:13.070Z"),
    "updatedBy" : "1",
    "updatedDate" : ISODate("2017-12-13T10:38:13.070Z"),
    "regularHours" : 3600,
    "regularRates" : 1500,
    "overtimeRates" : 400,
    "distanceRate" : 1000,
    "stopRate" : 50,
    "workerStatus" : "AVAILABLE",
    "userId" : 3,
    "__v" : 0
}

工作者集合：

{
    "_id" : ObjectId("5a310315f685dd5038fecaaa"),
    "userId" : 3,
    "accountId" : 1,
    "userType" : "DRIVER",
    "firstName" : "Karthi",
    "lastName" : "keyan",
    "email" : "karthikeyan.a1@gmail.com",
    "password" : "$2a$12$KFYc6riMnqTuzXhR0ssKZQmejAU4RF8FthAIQD4sgOUcALesp7DaJxK",
    "phone" : "xyz",
    "updatedAt" : ISODate("2017-12-13T10:38:13.492Z"),
    "createdAt" : ISODate("2017-12-13T10:38:13.492Z"),
    "__v" : 0
}

{
    "_id" : ObjectId("5a310315f685dd5038fecaab"),
    "workerId" : 1,
    "accountId" : 1,
    "name" : "Karthikeyan",
    "email" : "karthikeyan.a1@gmail.com",
    "mobile" : "xyz",
    "type" : "DRIVER",
    "joinDate" : ISODate("2017-12-13T10:38:13.070Z"),
    "assignedVehicleId" : "23423231",
    "licenseNumber" : "TN2506",
    "createdBy" : "1",
    "createdDate" : ISODate("2017-12-13T10:38:13.070Z"),
    "updatedBy" : "1",
    "updatedDate" : ISODate("2017-12-13T10:38:13.070Z"),
    "regularHours" : 3600,
    "regularRates" : 1500,
    "overtimeRates" : 400,
    "distanceRate" : 1000,
    "stopRate" : 50,
    "workerStatus" : "AVAILABLE",
    "userId" : 3,
    "__v" : 0
}

现在，我想使用userId同时删除这两个文档。

数据库适配器允许使用

null

调用

remove

，以及删除与该查询匹配的所有条目的查询（请参阅）。就你而言：

app.service('users').remove(null, { query: { userId: 3 } });
app.service('workers').remove(null, { query: { userId: 3 } });

可以在

之后的
中删除相关条目（例如，一旦用户被删除，则删除该用户的所有工作人员）：
