in your nested serializer pass these arguments.

class DriverEditListSerializer(serializers.ModelSerializer):
    city = CitySerializer(many=True, required=False, allow_null=True)
    location = LocationSerializer(many=True, required=False, allow_null=True)
    hstatus=HiringstatusSerializer(many=True, required=False, allow_null=True)
    class Meta:
        model = Driver
        fields = ( 'id','employee_id','employer', 'name','uber_name','uber_device_no', 'mobile', 'location', 'city','shift','status', 'aadhar_no','hstatus')
