Django：如何修改Model属性的值

Question

Say I have a Django Person model connected to a sqlite3 database:

 class Person(models.Model): name = models.CharField(max_length=128) def __unicode__(self): return self.name 

Then I create an instance

 person = Person.objects.get_or_create(name="Henry")[0] 

How can I now change the name of Henry ? I tried

Person.objects.get(pk=1).name = "Alfred"

(where pk=1 corresponds to the primary key (?) of Henry ) but the name remains Henry , as I can see in my Django Admin.

Answer 1

You have to save your change :

person = Person.objects.get(pk=1)
person.name = "Alfred"
person.save()
