Django throttle_scope doesn't seem to work
The problem I was trying to implement throttling following the django rest framework guide. Since I don't need to create another throttle class, I tried to use the .throttle_scope attribute. So, I implemented it like this: class MyView(APIView): throttle_scope = 'my_scope' def post(self, request) -> Response: # do something return Response(status=status.HTTP_200_OK) And in the settings I wrote something like this: REST_FRAMEWORK = { 'DEFAULT_THROTTLE_RATES': { 'my_scope': '1/minute', } } What I tried I tried, using postman, to make more than 1 request per minute to that endpoint and I never received a 429 code. Than I tried creating a new throttle class and using the .throttle_classes attribute, like this: class MyView(APIView): throttle_classes = [MyThrottle] def post(self, request) -> Response: # do something return Response(status=status.HTTP_200_OK) class MyThrottle(UserRateThrottle): scope = 'my_scope' I left the settings unchanged and it worked as expected. Possible solution? So now I'm wondering, could it be that the throttling_scope attribute only works if the user is anonymous? -
What is the relationship here, One to Many or a Many to Many?
I am building a project(using django) whereby agents are issued with phones. When a phone gets damaged the agent sends the phone to hq for repairs.

Is it possible to store a queue-like structure in Django database?
This might be a stupid question, but I'm new to databases and I could't find an answer anywhere. Is it possible to somehow store a FIFO queue in django? Some equivalent of python's collections.deque? Let's say I hypothetically have a model AverageRate, which stores a queue of up to 24 numbers and an average value of those numbers: (sum(numbers) / len (numbers)). class AverageRate: last_24_numbers = # FIFO queue up to 24 elements long average_value = # average value of last_24_numbers Every hour a function adds a new number to last_24_numbers and calculates average value. If the queue reaches 24 elements, then to append a new element to the end of the queue, it must pop the oldest element from the beginning of the queue. Honestly the only solution I came up with was to possibly convert the queue to string and store it in CharField, and then convert it back every time I need to use it. But I dunno... it just feels like not the best idea. I would obviously want to use the most efficient solution. -
