I have 3 models:
class Products(models.Model):
brand = models.ForeignKey(
Brands,
verbose_name = "Brand",
)
code = models.CharField("Code",
max_length=25,
)
descr = models.CharField("Description",
max_length=50,
)
class Orders(models.Model):
brand = models.ForeignKey(
Brands,
verbose_name = "Brand",
null=True,
blank=True,
related_name="ord_brand"
)
ord_date = models.DateField("Date")
ord_numb = models.CharField("Number",
max_length=20,
unique_for_year="ord_date",
)
class OrderRows(models.Model):
order = models.ForeignKey(
Orders,
verbose_name = "Order",
)
product = models.ForeignKey(
Products,
verbose_name = "Product",
)
price = models.DecimalField("Price",
max_digits = 11,
decimal_places=2,
)
In my Admins.py I have a ModelAdmin for Orders whit a Inline for OrderRows.
How can I filter the product queryset in OrderRows where brand=orders.brand?
