@property
def policy_escape(self):
if self.date - datetime.date.today:
self.status = 2
self.save()
def save(self, *args, **kwargs):
self.counter = counter + 1
I have this logic for policies. For every policy created I want to increase a property nnumber(this is not exact my case).
I want when policy date is today date to change the status of that policy. But when I change it, the policy counter is increasing.
Can someone help me to update only status without updating other properties?
Thanks in advance
You could limit the update_fields:
@property
def policy_escape(self):
if self.date - datetime.date.today:
self.status = 2
self.save(update_fields=("status",))
However, the particular Python object would still have the changed counter. So you would have to avoid any other save calls on that object.
You could instead pass a custom kwarg:
@property
def policy_escape(self):
if self.date - datetime.date.today:
self.status = 2
self.save(update_counter=False)
def save(self, *args, **kwargs, update_counter=True):
if update_counter:
self.counter += 1
# ...
super().save(*args, **kwargs):
Another way to avoid save being called at all is using Queryset.update instead:
@property
def policy_escape(self):
if self.date - datetime.date.today:
self.__class__.objects.filter(pk=self.pk).update(status=2)
# self.status = 2 # if the current object should reflect that change
