In this: class Administrator(models.Model): user = models.OneToOneField(User, primary_key=True) account = models.ForeignKey(Account) class Meta: unique_together = (('account', 'self.user.username'),) The self.user.username part is obviously incorrrect.

The assumption is that running get_query_set() will return a filtered query that contains all the fields in the list and some others that may not play so well with a Sum aggregate (date fields, char fields, Foreign Keys, etc...

Right now I have to write a view to pass data to a tempate. I've only seen it done in the django manual: there ObjectName.o...
The Django docs only list examples for overriding save() and delete(). However, I'd like to define some extra processing for my models only when they are created. For anyone familiar with Rails, it would be the equivalent to creating a :before_create filter. Is this possible? ...

In addition to having a decorator that connects the decorated method to a signal (with the signal's sender as an argument to the decorator), I would like to use the decorator on class methods.
