region, which has its own taxes. I'd like to associate the tax to the
region and calculate it.
class TaxReference(models.Model):
region = models.CharField(max_length=100)
. . .
tax_multiplier = models.DecimalField(max_digits=3,
decimal_places=2)
def __unicode__(self):
return unicode(self.region)
class Product(models.Model):
title = models.CharField(max_length=100)
. . .
price = models.DecimalField(max_digits=10, decimal_places=2)
tax = models.ForeignKey(TaxReference)
def __unicode__(self):
return self.title
def taxedprice(self):
return self.price*TaxReference.tax_multiplier
The very last line of code is what I'm trying to accomplish.
How would I return the calculation to get the taxedprice, since the
tax_multiplier is in another table (but its a foreign key in Product)?
