DRF is not updating the database - django

Question

Here's the model:
from django.db import models
from datetime import datetime, timedelta
# Create your models here.
def set_expiration():
return datetime.today().date() + timedelta(days=30)
class Customer(models.Model):
email = models.EmailField(max_length=254, unique=True)
created_on = models.DateField(auto_now_add=True)
expires_on = models.DateField(editable=False, default=set_expiration())
def __str__(self):
return self.email
And this is the view:
#api_view(['POST'])
def update_customer(request):
try:
customer = Customer.objects.get(email=request.data['email'])
except ObjectDoesNotExist:
return Response(status=status.HTTP_404_NOT_FOUND)
serializer = CustomerSerializer(instance=customer, data=request.data)
if serializer.is_valid(raise_exception=True):
serializer.save()
return Response(serializer.data)
And the serilizer:
from rest_framework import serializers
from .models import Customer
class CustomerSerializer(serializers.ModelSerializer):
class Meta:
model = Customer
fields = '__all__'
At this moment I have a record in database with expires_on set to 2022-03-14 and I want to update that to 2024-12-12 so I call the endpoint with the following data:
{
"email": "myemail#mydomain.com",
"expires_on": "2024-12-12"
}
The view returns this:
{
"id": 1,
"email": "myemail#mydomain.com",
"created_on": "2022-02-12",
"expires_on": "2022-03-14"
}
This is the existing data. expires_on is not updated with the new value.
I get no error and no exception. It just doesn't work.

Answer 1

Remove editable=False from expires_on field.
class Customer(models.Model):
email = models.EmailField(max_length=254, unique=True)
created_on = models.DateField(auto_now_add=True)
expires_on = models.DateField(default=set_expiration())
def __str__(self):
return self.email
