Hi everyone,
I want to add an integer field to a table callled "position" to do
ordering by. I would like the field to auto-increment based on the
count of objects.
I've tried overriding the save() method of the model, but this doesn't
seem to work with the admin.
Here's some simple test code for my model:
class Link(models.Model):
friendly_name = models.CharField(max_length=100)
url = models.URLField('Website Address', verify_exists=True,
help_text='Ener the full URL, including http://')
position = models.PositiveSmallIntegerField(editable=False) #to
hide in admin
def __unicode__(self):
return self.friendly_name
def save(self):
position = 1
super(Link, self).save()
class Admin:
pass
That should just make the position column = 1, but I get an error
saying that "position" can't be null. Advice appreciated!
Thanks,
Brandon
