Hello. I'm using Django 1.3.1.
I've got some strange behaviour while deleting an object in admin
panel.
Here's the code from models.py:
class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def was_published_today(self):
return self.pub_date.date() == datetime.date.today()
was_published_today.short_description = 'Published today?'
def __unicode__(self):
return self.question
def delete(self, using=None):
print "Deleted"
super(Poll, self).delete(using)
It is just the code from django tutorial with delete() method
overriden.
There was an issue:
https://code.djangoproject.com/ticket/11022
If I open the object's properties page and delete an object using
Delete button on that page everything works fine and message displays
in the console.
But if I check the object's checkoxes (insted of opening their
property list pages), select "Delete selected polls" action and press
the Go button, the Delete multiple objects page opens.
Then I press "Yes, I'm sure button" and objects are successfully
deleted.
But their delete() method are not triggered so i don't get the message
"Deleted" in the console.
It does not matter if I choose one or multiply objects - the message
still does not appear in the console.
Should I consider this behaviour as a bug or I am doing something
wrong?
The delete select action uses the queryset's delete method [1], which
means the model's delete method is not called.
It's not a bug, the behaviour is documented on the admin actions page. [2]
Cheers,
Alasdair
