[英]In Mongoose/MongoDB, how to update properties in an array of an array
我有以下模型:
訂單模型:
var order = new Schema({
content: [{
product: {type: String, required: true},
quantity: {type: Number},
vatRate: {type: Number, required: true},
price: {type: Number},
deviceId: {type: String}
}],
number: {type: Number},
tableId: {type: Schema.ObjectId, ref: 'Table'}
isAutomated: {type: Boolean, default: true},
createdAt: {type: Date, default: Date.now}
});
表模型:
var table = {
tableNumber: {type: Number, default: 0},
status: {type: String, enum: ['Booked', 'Free', 'Active'], default: 'Free'},
order: [order]
};
設備型號:
var device = {
deviceId: {type: String, required: true},
status: {type: String, enum: ['Booked', 'Free', 'Active'], default: 'Free'},
token: {type: String},
tableId: {type: Schema.ObjectId, ref: 'Table'},
isEnabled: {type: Boolean, default: true}
};
客戶模型:
var client = new Schema({
information: {
code: {type: String, required: true},
name: {type: String, required: true}
},
account: {
username: {type: String, required: true},
password: {type: String, required: true},
token: {type: String}
},
devices: [device],
tables: [table],
products: [product],
notifications: [notification],
createdAt: {type: Date, default: Date.now}
});
一個客戶端有多個表。 一個表有多個訂單。
如何更新訂單數組中的訂單,訂單本身又是表格中的數組?
在我的代碼的另一部分中,我知道當只有一個級別的數組時該怎么做……像這樣:
clientModel.findOneAndUpdate(
{
"information.code": clientCode,
'devices.deviceId': deviceId
},
{
$set: {
'devices.$.status': device.status,
'devices.$.tableId': device.tableId
}
},
{
new: true,
select: {
devices: {
$elemMatch: {deviceId: deviceId}
}
}
},
但是如何使用嵌套數組呢?
謝謝你的幫助,

使用$ push運算符更新數組條目。 嵌套數組可以使用'。'訪問。 此處解釋的符號
