Jake and Zerek,
I will able to fix the problem thanks to your suggestions. It turns
out that instead of using 'a.price' I have to use 'a.price.name'.
Below is my model code:
class Price(models.Model):
name = models.DecimalField(max_digits=6, decimal_places=2)
price_cat = models.ForeignKey(PriceCategory)
def __str__(self,):
return str(self.name)
class Admin:
pass
class Choice(models.Model):
choice = models.ForeignKey(Collection, edit_inline=models.TABULAR,
num_in_admin=5)
size = models.ForeignKey(Size, core=True)
price = models.ForeignKey(Price, core=True)
/////////////////
My for loop in my template contained all of my choices that fit the
criteria. Notice how 'price' is a ForeignKey to the Price class.
We'll when I did a 'a.price' I guess that was returning a string based
on 'def __str__(self,): return str(self.name)'. So in my template I
changed it to a.price.name and it works. The two zeros now appear.
Thanks for your help
