Get constant incoming post requests from multiple devices with Django Rest Framework or listen TCP Server Socket
I have IoT devices which are rfıd readers. This devices send stream data with HTTP Post message. I use Django to get data from these devices. While receiving this data, I can write a function to get data from post requests coming directly with Django and receive the data from the request in this function with Django REST Framework or I can listen with a TCP Server socket. Which of these two approaches is more suitable for retrieving data? Because when I use a TCP Server socket, Django REST Framework does not work for HTTP requests, only the TCP socket works. -
How to add a property to a model which will be calculated based on input?
class TransactionHistory(models.Model): from_account = models.ForeignKey( 'Account', on_delete=models.CASCADE, related_name='from_account' ) to_account = models.ForeignKey( 'Account', on_delete=models.CASCADE, related_name='to_account' ) amount = models.DecimalField( max_digits=12, decimal_places=2 ) created_at = models.DateTimeField(default=timezone.now) @property def way(self): # Here I need to access a list of user's accounts # (request.user.accounts) to mark the transaction # as going out or in. return def get_own_transaction_history(me_user): my_accounts = me_user.accounts.all() # TODO: mark transactions with way as in and out own_transactions = TransactionHistory.objects.filter( Q(from_account__in=my_accounts) | Q(to_account__in=my_accounts) ) return own_transactions I want to add a "way" property for the model so when I return the queryset via serializer, the user could understand if the transaction is for going out from his account or in. But if I just add property, it can not be calculated with me_user user in mind, AFAIK the property can only access the local model fields like "from_account" or "to_account". -
