I have the following model:
An order model:
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}
});
A table model:
var table = {
tableNumber: {type: Number, default: 0},
status: {type: String, enum: ['Booked', 'Free', 'Active'], default: 'Free'},
order: [order]
};
A device model:
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}
};
A client model:
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}
});
A client has multiple tables. A table has multiple orders.
How can I update an order which is in an array of orders and itself is in an array of tables ?
In another part of my code, I know how to do it when there is only one level of array...like that:
clientModel.findOneAndUpdate(
{
"information.code": clientCode,
'devices.deviceId': deviceId
},
{
$set: {
'devices.$.status': device.status,
'devices.$.tableId': device.tableId
}
},
{
new: true,
select: {
devices: {
$elemMatch: {deviceId: deviceId}
}
}
},
But how to do it with nested arrays ??
Thanks for your help,
Patrice
Use $push operator to update array entries. Nested arrays can be accessed using the '.' notation as explained here
