Answer 1

You already have user as a FK seller_id = models.ForeignKey(User, on_delete=models.CASCADE) If you want to check if that user is a seller. Assuming this boolean field is called is_seller

User.objects.filter(is_seller=True)

This command fill give you all users who are sellers. You can filter it even more to suit your needs
