Question

I have a model called Product with a custom property:

def _get_active(self):
    o = get_option()
    if self.date_expiration == None:
        return True
    if self.date_expiration <= o.working_month:
        return False
    return True
active = property(_get_active)

… and in one of my methods, I have this line:

products = g.product_set.filter(active__exact=True)

But despite the fact that (I think) I’ve correctly set up the property, the above line gives me “Cannot resolve keyword ‘active’ into field.” What am I missing here?

Thanks in advance.

You can only query on actual fields, not properties.
