say for instance you had a CartItem that was laid out pretty much as
follows
class CartItem(models.Model):
cart_id = models.CharField(max_length=50)
date_added = models.DateTimeField(auto_now_add=True)
quantity = models.IntegerField(default=1)
size = models.CharField(max_length=20)
product = models.ForeignKey('shop.Product', unique=False)
and you extended the shop to include products that can be found in
different apps, eg shop.Product as well as farm.Product
This has been done because the two Product models are vastly different
and so can't coexist in the same table.
is there a simple way of splitting the product out such that i can
refer to it as app and product, maybe by storing the app and the id?
class CartItem(models.Model):
cart_id = models.CharField(max_length=50)
product_app = models.CharField(max_length=50)
product_type = models.CharField(max_length=50)
product_id = models.CharField(max_length=50)
and if there is, how would i go about doing the following step:
p = get_object_or_404(Product, product_slug=product_slug)
im guessing there will need to be an intermediate step of
model = get_model(product_app, product_type)
p = get_object_or_404(model, id=product_id)
surely there is a far simpler cleverer way fo doing this? what do i
need to be reading about to do this?
