Django: Get all inline objects in Admin's save_model
I have two related (via foreignKey relation) models and created admin model for parent with inlines. In a certain use-case, I need to fetch all related models and use those to update 1 particular field for parent model. What is the efficient way to do it?

Race condition when two different users inserting new records to database in Django
There is a race condition situation, when I want to create a new instance of model Order. There is a daily_id field that everyday for any category starts from one. It means every category has its own daily id. class Order(models.Model): daily_id = models.SmallIntegerField(default=0) category = models.ForeignKey(Categoty, on_delete=models.PROTECT, related_name="orders") declare_time = models.DateField() ... } daily_id field of new record is being calculated using this method: def get_daily_id(category, declare_time): try: last_order = Order.objects.filter(declare_time=declare_time, category=category).latest('daily_id') return last_order.daily_id + 1 except Order.DoesNotExist: # If no order has been registered in declare_time date. return 1 The problem is that when two different users are registering orders in the same category at the same time, it is highly likely that the orders have the repetitive daily_id values. I have tried @transaction.atomic decorator for post method of DRF APIView and it didn't work! -
