Hello!
I'm building a sort of b2b app that lists a car catalogue. A car can
have multiple 'special prices', linked to groups of wholesalers. So
when wholesaler W logs into the app, he should see a 'special price
just for you' control, displaying the proper price.
In a custom app I'd have a 'modified' m2m relationship, sort of like this:
SpecialPrices
idCars (int FK)
idWholesalers (int FK)
Price (float)
The problem is, I don't know how to do this in Django. I tried doing:
class SpecialPrice(models.Model):
""" A price for a special user (company)"""
user = models.ForeignKey(User)
special_price = models.FloatField("Custom Price", max_digits=9,
decimal_places=2)
class Car(models.Model):
#...
special_prices = models.ManyToManyField(SpecialPrice,
filter_interface=models.HORIZONTAL)
... but that's not what I mean. I need the special prices to be unique
to Car and Wholesaler.
Could anyone be so kind as to shed some light on how to do this, the Django way?
Mil gracias,
