(Assuming the time field should be stored in the database)
Simplest, but specific for temporal fields:
class Test(models.Model) :
start_time = models.DateTimeField(auto_now_add=True)
end_time = models.DateTimeField(auto_now_add=True)
time = models.DateTimeField(auto_now_add=True)
Generally working:
class Test(models.Model) :
first = models.CharField(max_length=10, default='first')
second = models.CharField(max_length=10)
def __init__(self, *args, **kwargs) :
first = kwargs.get('first', False)
if not first :
first = self.__class__.first.default
second = first
if not kwargs.get('second', False) :
kwargs['second'] = second
super(Test, self).__init__(*args, **kwargs)
For the admin, see
<https://docs.djangoproject.com/en/1.4/ref/contrib/admin/#django.contrib.admin.ModelAdmin.prepopulated_fields>
for an alternate solution.
