I am developing a store using Satchmo, and I want the ability to save
quotes; that's snapshots of the current cart, and I want to store the
history of all the quotes in the database. My current models look like
this:
class QuoteItem(models.Model, Product):
quantity = models.PositiveIntegerField(_('Quantity'))
price_incl_vat = models.DecimalField(_("Price incl. VAT"),
max_digits=10, decimal_places=2)
class Quote(models.Model):
items = models.ManyToManyField('QuoteItem')
In Django my inherited Product class is represented as a foreign key
in the QuoteItem table. The problem is that the product price is
subject to change in the future, but the Quote shouldn't change.
I want a copy of the product attributes in QuoteItem, instead of a
foreign key.
Is there a clean way to do, or do I have to copy all the attributes
here manually?
