Node.js 猫鼬上的多个一对多关系

我使用mongoose来存储三个模型的文档，有时我必须在这三个模型之间更新引用，为此我使用， 我需要的是这样的参考：

• 一个客户有很多时间表
• 一个客户有很多订单
• 一个订单有很多时间表

当我创建订单时，我需要将计划id推送到订单中以供参考。但每个集合只能引用一个childPath，我的模型是这样映射的

顾客：

var CustomerSchema = new Schema({
    name: {type: String, required: true},
    email: {type: String, required: true},
    shedules: [{ type:mongoose.Schema.Types.ObjectId, ref:"Schedule" }],
    orders: [{ type:mongoose.Schema.Types.ObjectId, ref:"Order" }]
}

附表：

var ScheduleSchema = new Schema({
    customer: {type:mongoose.Schema.Types.ObjectId, ref:"Customer", childPath:"shedules"}, //shedule id
    order: {type:mongoose.Schema.Types.ObjectId, ref:"Order", childPath:"shedules"}, //order Id
    sequence: {type: Number, default: 0},
    creation_date: {type: Date, default: Date.now}
}
SheduleSchema.plugin(relationship, {relationshipPathName:['customer','order']});

订单：

var OrderSchema = new Schema({
    customer: {type:mongoose.Schema.Types.ObjectId, ref:"Customer", childPath:"order"},
    shedules: [{type:mongoose.Schema.Types.ObjectId, ref:"Shedule" }],// <-- this field doesn't update.
    price: {type: Number, default: 0}
}
OrderSchema.plugin(relationship, { relationshipPathName:'customer' });

var OrderSchema=新模式({
客户：{type:mongoose.Schema.Types.ObjectId，ref:“客户”，childPath:“订单”}，
日程安排：[{type:mongoose.Schema.Types.ObjectId，ref:“日程安排”}]//
