Hi all,
I've just used a proxy model in my own custom application and i've just
found a small problem. Right now, to be able to create a Proxy model, i'm
force to redefine a Meta options like that:
class NewDiscount(Discount):
class Meta:
proxy = True
The problem i have is that the original discount object defined the
following Meta options:
class Discount(models.Model):
class Meta:
verbose_name = _("Discount")
verbose_name_plural = _("Discounts")
unique_together = ('slug', 'amount')
Since i've overwritten the Meta class I should copy the original Meta
options inside my Proxy model like that:
class NewDiscount(Discount):
class Meta:
proxy = True
verbose_name = _("Discount")
verbose_name_plural = _("Discounts")
unique_together = ('slug', 'amount')
But, when I'm doing that, Django throw me an error saying:
"store.discount: "unique_together" refers to site. This is not in the same
model as the unique_together statement."
It means that i can't add the unique_together clause in the Meta class cause
the fields are not directly the property of my proxy model !!!
How it's possible ? What should I do ?
