I am developing a web with django, and in my model I need to superclass
all model classes with a superclass that add some methods.
The problem is django-admin.py create a dummy table not needed for this
superclass. I know that multiple-inheritance can be useful here, but I
can consider some times that multiple-inheritance doesn't works (for
example, I wanted to change __metaclass__ of several classes in my
model).
I patched django for permit abstract classes in a model. My syntax maybe
doesn't like to someone...
Here are a model example of use:
class FooSuperclass(models.Model):
__abstract__ = True
def oneFunction(self, x, y):
...
class FooClass(FooSuperclass):
age = models.IntegerField()
