AttributeError: 'Person' object 没有属性 'update' Django

Question

Im having a problem with this query. All I want is to change the paid value if the paid is equals to Yes then it must be change into Paid and if paid is equals to No then it is Unpaid . The problem is Im having this kind of error AttributeError: 'Person' object has no attribute 'update' . It is necessary to use p.update ? to change the value from Yes to Paid ?

This is what I've been trying

  for p in Person.objects.filter(Q(paid = 'Yes')):
      p.update(paid="Paid")

Answer 1

You can either save each object.

for p in Person.objects.filter(Q(paid = 'Yes')):
      p.paid = "Paid"
      p.save()

OR

update method is available on QuerySet , hence you can use

Person.objects.filter(Q(paid = 'Yes')).update(paid="Paid")
