Parse json to Mongoose schema

My mongoose schema:

const BillSchema = new Schema({
    fromDate: { type: Date, default: Date.now },
    toDate: { type: Date, default: Date.now },
    phoneNumber: { type: String },
    created: { type: Date},
    user: { type: Schema.ObjectId, ref: 'User' },
    billDetail: [{ type: Schema.Types.ObjectId, ref: 'BillDetail' }]
});
const BilldetailSchema = new Schema({
    amount: { type: Number },
    item: { type: Schema.ObjectId, ref: 'Item' },
    created: { type: Date, default: Date.now },
    user: { type: Schema.ObjectId, ref: 'User' }
});
const ItemSchema = new Schema({
    name: { type: String},
    code: { type: String},
    amount: { type: Number },
    created: { type: Date, default: Date.now },
    user: { type: Schema.ObjectId, ref: 'User' }
});

My Json get from client 

{ billDetail: [ { item: [Object], amount: 1, rentalPrice: 11, rentalDays: 1 } ],
  code: '000001',
  customerName: 'steve',
  phoneNumber: '959494949',
  fromDate: '2017-05-07T17:00:00.000Z',
  toDate: '2017-05-18T17:00:00.000Z' }

How can i parse json string above to bill object? I try to use this code: 

let bill = new Bill(req.body);

but it's not working, it's only returning bill, but not billdetails.

billDetail should be an array of ids, not the objects.

You can insert bill details first, obtain their ids, and then push them to a new billDetail array.

BillDetail.insertMany(req.body.billDetail)
    .then(function(billDetails) {
         const billDetail = billDetails.map(billDetail => billDetail._id);
         const billData = Object.assign({}, req.body, { billDetail });
         const bill = new Bill(billData);
    })
    .catch(function(err) {
        // error handling here
    });
