Updating object using super().update() - django-rest-framework

Question

I have an object, whose attributes I would like to update. Right now, I am able to update a single attribute eg: name. But the object has several attributes which include name, contact_name, contact_email and contact_phone_number.The following is what I have at the moment.
In views.py
class MerchantViewSet(GetPrefixedIDMixin, viewsets.ModelViewSet):
"""POST support for /merchants/."""
print ("in MerchantViewSet")
queryset = models.Merchant.objects.all()
serializer_class = serializers.CreateMerchantSerializer
lookup_field = "id"
# lookup_value_regex = f"{models.Merchant.id_prefix}_[a-f0-9]{32}"
lookup_value_regex = ".*"
permission_classes = [permissions.MerchantPermission]
def get_queryset(self):
"""Filter the queryset based on the full merchant name or starting with a letter."""
queryset = models.Merchant.objects.all()
search_param = self.request.query_params.get("search", None)
if search_param:
if search_param.startswith("^"):
queryset = queryset.filter(name__istartswith=search_param[1:])
else:
queryset = queryset.filter(name__icontains=search_param)
return queryset
def update(self, request, *args, **kwargs):
request.data["user"] = request.user.id
print (self.get_object().name)
print (request.data)
merchant = self.get_object()
print (response)
print (merchant.name)
for merchants in models.Merchant.objects.all():
print (merchants.id)
if (merchants.id == merchant.id):
merchants.name = request.data["name"]
merchants.save()
I've tried using
response = super(MerchantViewSet, self).update(request, *args, **kwargs)
from what I read in the DRF documentations but using this just returns error 404 when I run my test. Do I simply have to do with I did with name in my code above, with the other attributes? Or is there a more streamlined way to do this?
This is my test:
class MerchantsViewSetTest(tests.BigETestCase): # noqa
#classmethod
def setUpClass(cls): # noqa
super(MerchantsViewSetTest, cls).setUpClass()
cls.application = tests.get_application()
tests.create_group("merchant")
cls.consumer_user = tests.create_consumer()
cls.admin = tests.create_administrator()
cls.merchant_geraldine = models.Merchant.objects.create(
name="Test Account 1",
contact_name="Geraldine Groves",
contact_email="geraldine#example.com",
contact_phone_number="[phone]",
)
cls. merchant_barbara = models.Merchant.objects.create(
name="Account 2",
contact_name="Barbara",
contact_email="barbara#example.com",
contact_phone_number="[phone]",
)
def test_edit_merchant(self): # noqa
url = reverse("bige_transactions:merchant-detail", kwargs={'id': self.merchant_geraldine.prefixed_id})
# payload
data = {"name": "Edited"}
# Put data
resp_data = self.put(url, data, user=self.admin, status_code=200)
# Check if data was updated
url = reverse("bige_transactions:merchant-list")
# Try without authenticated user
self.get(url, status_code=401)
# Try with authenticated admin user
resp_data = self.get(url, user=self.admin, status_code=200)
print (resp_data)
