Invalid embedded document instance provided to an EmbeddedDocumentField

[prabin525]

I am currently working on an billing app and require to have orders inside a bill for that I have following two models Bill and orders ` class Bill(Document): billNo = IntField(unique=True, blank=False) table = ReferenceField('Table',reverse_delete_rule=1) orders = EmbeddedDocumentListField('Order', required = False) total = models.FloatField() discount = models.FloatField(blank=True) grandtotal = models.FloatField() payment_option = ReferenceField('PaymentOption',reverse_delete_rule=1) paid = models.BooleanField(default=False)

class Order(EmbeddedDocument): food = ReferenceField(Food) quantity = IntField(required = True) complementory = BooleanField(default = False) `

and their serializers are as

`class OrderSerializer(EmbeddedDocumentSerializer): class Meta: model = Order fields = 'all' read_only_fields = ('id',)

class BillSerializer(DocumentSerializer): orders = OrderSerializer(many = True)

class Meta:
    model = Bill
    fields = '__all__'
    read_only_fields = ('id',)

def create(self, validated_data):
    orders = validated_data.pop('orders')
    bill = Bill.objects.create(**validated_data)
    bill.orders = []

    for order in orders:
        print(order)
        bill.orders.append(order)

    bill.save()

    return bill`

But whenever I pass a json like ` { "billNo": "4", "table":"5a93eb7f59951a3320a0b4d8", "payment_option":"5a93eddf59951a2fd4dbabe9", "orders":[{ "food":"5a93c2c759951a018c5e18b5", "quantity":"2", "complementory":"False" }]

}`

the bill object is created but the order is not added and it gives the error mongoengine.errors.ValidationError: ValidationError (Bill:5a94f76859951a19d4688aeb) (Invalid embedded document instance provided to an EmbeddedDocumentField: ['orders'])

I am using django rest framework and since it is mongodb i am using django rest framework mongo engine but i guess this is an mongo engine error.
