Django Nested Serializer does not find attribute - django

Question

This are my models
class OWNER_STORE(models.Model):
_id = models.CharField(max_length=120, unique=True, default=uuid.uuid4)
MSE_STORE_TYPE = models.ForeignKey(STORE_TYPE)
MSE_OWNER_INFO = models.ForeignKey(OWNER_INFO, related_name='STORES')
STORE_NAME = models.CharField("STORE_NAME", max_length=250, null=True, blank=True)
STORE_ID = models.IntegerField("STORE_ID", null=True, blank=True)
STORE_ADDRESS_HOUSE = models.CharField("STORE_ADDRESS_HOUSE", max_length=250, null=True, blank=True)
STORE_ADDRESS_ROAD = models.CharField("STORE_ADDRESS_ROAD", max_length=250, null=True, blank=True)
STORE_ADDRESS_VILLAGE = models.CharField("STORE_ADDRESS_VILLAGE", max_length=250, null=True, blank=True)
STORE_ADDRESS_UNION = models.CharField("STORE_ADDRESS_UNION", max_length=250, null=True, blank=True)
STORE_ADDRESS_THANA = models.CharField("STORE_ADDRESS_THANA", max_length=250, null=True, blank=True)
STORE_ADDRESS_DISTRICT = models.CharField("STORE_ADDRESS_DISTRICT", max_length=250, null=True, blank=True)
STORE_ADDRESS_DIVISION = models.CharField("STORE_ADDRESS_DIVISION", max_length=250, null=True, blank=True)
STORE_EMPLOYEE_STATUS = models.BooleanField("EMPLOYEE_STATUS")
STORE_NUMBER_OF_EMPLOYEE = models.IntegerField("NUMBER_OF_EMPLOYEE", null=True, blank=True)
STORE_AVG_REVENUE = models.IntegerField("STORE_AVG_REVENUE", null=True, blank=True)
STORE_AVG_COGS = models.IntegerField("STORE_AVG_COGS", null=True, blank=True)
STORE_AVG_PROFIT = models.IntegerField("STORE_AVG_PROFIT", null=True, blank=True)
STORE_CUSTOMER_CREDIT_LIMIT = models.IntegerField("CUSTOMER_CREDIT_LIMIT", null=True, blank=True)
STORE_BUSINESS_TARGET = models.IntegerField("BUSINESS_TARGET", null=True, blank=True)
STORE_REORDER_THRESHOLD = models.IntegerField("REORDER_THRESHOLD", null=True, blank=True)
STORE_PASSWORD = models.TextField("STORE_PASSWORD", max_length=50, default=None, null=True, blank=True)
def __str__(self):
return str(self.id)
class MSE_EMPLOYEE(models.Model):
emp_id = models.IntegerField(null=True, blank=True)
store = models.ForeignKey(OWNER_STORE)
MSE_EMPLOYEE_ID = models.IntegerField(null=True, blank=True)
MSE_EMPLOYEE_NAME=models.CharField(max_length=250, null=True, blank=True)
MSE_EMPLOYEE_MOBILE_NUMBER = models.CharField(max_length=250, null=True, blank=True)
MSE_EMPLOYEE_JOINING_DATE = models.DateField(null=True, blank=True)
MSE_EMPLOYEE_SALARY = models.IntegerField(null=True, blank=True)
def __str__(self):
return str(self.MSE_EMPLOYEE_NAME)
For my serializers.py, I did this
class STORE_EMPLOYEE_SERIALIZER(serializers.ModelSerializer):
employees = EMPLOYEE_SERIALIZER(many=True)
class Meta:
model = OWNER_STORE
fields=("MSE_STORE_TYPE", "MSE_OWNER_INFO", "STORE_NAME", "STORE_ID", "STORE_ADDRESS_HOUSE", "STORE_ADDRESS_ROAD",
"STORE_ADDRESS_VILLAGE", "STORE_ADDRESS_UNION", "STORE_ADDRESS_THANA", "STORE_ADDRESS_DISTRICT",
"STORE_ADDRESS_DIVISION", "STORE_EMPLOYEE_STATUS", "STORE_NUMBER_OF_EMPLOYEE",
"STORE_AVG_REVENUE", "STORE_AVG_COGS", "STORE_AVG_PROFIT", "STORE_CUSTOMER_CREDIT_LIMIT",
"STORE_BUSINESS_TARGET", "STORE_REORDER_THRESHOLD", "STORE_PASSWORD", "employees")
I was hoping that with a get request, I would get all the employees under store but I keep getting this error.
AttributeError: 'OWNER_STORE' object has no attribute 'employees'
and on the last line of terminal,
AttributeError: Got AttributeError when attempting to get a value for field employees on serializer STORE_EMPLOYEE_SERIALIZER.
The serializer field might be named incorrectly and not match any attribute or key on the OWNER_STORE instance.
Original exception text was: 'OWNER_STORE' object has no attribute 'employees'.

Answer 1

You need use MSE_EMPLOYEE_set instead employees.
Or add related_name to the store = models.ForeignKey(OWNER_STORE)
store = models.ForeignKey(OWNER_STORE, related_name='employees')
