Hi all,

I hope i can explain my query problem well. Think you have 3 classes:

class City( models.Model ):
...
...

class Brand( models.Model ):
...
...

class Shop( models.Model ):
   brand = models.ForeignKey( Brand )
   city = models.ForeignKey( City )
...
...

class Discount( models.Model ):
   brand = models.ForeignKey( Brand )
...
...

Think a Shop sell products of a single Brand. I have lots of Discount
records. But i'm interested in Discounts at Shops in Paris. Is there
any?

Can you help me?

Thanks,
