How to define multiple throttle in django rest framework

Question

The documentation of django_Rest_framework states:

Multiple throttles can also be used if you want to impose both burst throttling rates, and sustained throttling rates. For example, you might want to limit a user to a maximum of 60 requests per minute, and 1000 requests per day.

However, it is not explained how to implement a situation like it.

I've tried something like this but it didn't work

REST_FRAMEWORK = {
    'DEFAULT_THROTTLE_CLASSES': (
        'rest_framework.throttling.AnonRateThrottle',
        'rest_framework.throttling.UserRateThrottle'
    ),
    'DEFAULT_THROTTLE_RATES': {
        'anon': '100/day',
        'user': ['30/minute', '1000/day']
    }
}

Answer 1

It is possible but it is necessary to define multiple limits, one for each time unit.

1. First you define in the settings all the limits you need, for example no more than 30 per minute and no more than 1000 per day.

        REST_FRAMEWORK = {
          'DEFAULT_THROTTLE_CLASSES': (
                    'rest_framework.throttling.AnonRateThrottle',
              'rest_framework.throttling.UserRateThrottle'
          ),
          'DEFAULT_THROTTLE_RATES': {
              'anon': '100/day',
              'user_min': '30/minute',
              'user_day': '1000/day',
          }
        }

2. You add Throttling classes as subclasses of UserRateThrottle with the scopes you defined:

from rest_framework.throttling import UserRateThrottle

class UserMinThrottle(UserRateThrottle):
             scope = 'user_min'

3. Finally on the APIView you set as throttle_classes the classes with the limits you defined on the previous step.

class YourAPIView(APIView):
     throttle_classes = [
          UserMinThrottle,
          UserDayThrottle
     ]
