You have a ManyToManyField, not ForeignKey, from Product to Category.
Which means that "product.category" is not a single object and hence
can't be represented as a single category name. Is this ManyToMany
intentional? If not, change it to ForeignKey and your __str__ will look
right. If yes, you can construct a list of categories in your __str__:
def __str__(self):
return '%s (%s)' % (self.name, ', '.join(self.category.all()))
