Currently, I am utilizing Expressjs alongside mongoosejs for my project. The connection between the collections CustomerId has been established in the code snippet below:
.
.
/**
* Customer Schema
*/
var CustomerSchema = new Schema({
id : Number,
name: String,
joined: { type: Date, default: Date.now },
city: String
});
mongoose.model('Customer', CustomerSchema);
.
.
/**
* Order Schema
*/
var OrderSchema = new Schema({
id : Number,
products: [Schema.Types.Mixed],
total: Number,
comments: String,
customerId: {type: Number, ref: 'Customer'}
});
mongoose.model('Order', OrderSchema);
.
.
exports.customerOrders = function (req, res) {
return Order.find({customerId: req.params.customerId}, function (err, orders) {
Order.populate(orders, {path: 'customerId', model: 'Order'}, function (err, orders) {
if (!err) {
return res.json(orders);
} else {
return res.send(err);
}
});
});
};
After running the above code, an error occurred:
{
message: "Cast to ObjectId failed for value "1" at path "_id"",
name: "CastError",
type: "ObjectId",
value: 1,
path: "_id"
}
Please note that the relationship should be based on id rather than _id.
I require assistance in correctly using the populate method.
Thank you,
