Hi,
So you want to tie Contract with Product(s) with rebate_pct? You then need
custom intermediary m2m table say "ContractProduct" <see
https://docs.djangoproject.com/en/1.3/topics/db/models/#intermediary-manytomany>
for more. So in the end your models would probably look a alike following:
class Contract():
contract_id = models.lIntegerField(...)
products = models.ManyToManyField(Product, through='ContractProduct')
class ContractProduct():
contract = models.ForeignKey(Contract)
product = models.ForeignKey(Product)
rebate_pct = models.DecimalField(max_digits=4, decimal_places=2)
So now you can link Contract with multiple Products adding custom rebate_pct
value to each link.
And what comes to rebate value, I think you want to keep value with product
linkage for two reasons:
1) It's a single scalar value
2) It's probably something that should not be changed ever after saving.
hth,
