💡 Hint

Common Mistakes

Using permission classes instead of throttle classes.

Fix the error in the throttle rate setting in Django REST Framework settings.

Django

"DEFAULT_THROTTLE_RATES": {
    "user": "[1]"
}

Drag options to blanks, or click blank then click option'

A1000/hour

B1000 per hour

C100/hour

D1000/hourly

💡 Hint

Common Mistakes

Using incorrect time units like 'hourly'.

Adding extra words like 'per'.

The throttle rate must be a string with a number and a time unit separated by a slash, like '100/hour'.

4fill in blank

hard

Fill both blanks to create a custom throttle class that limits requests to 10 per minute.

Django

from rest_framework.throttling import [1]

class CustomThrottle([2]):
    rate = '10/minute'

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Inheriting from the wrong base class.

Importing a class but not using it correctly.

Custom throttles usually inherit from SimpleRateThrottle to define a custom rate. The import should be SimpleRateThrottle since the class inherits from it.

5fill in blank

hard

Fill all three blanks to apply throttling globally in Django REST Framework settings.

Django

REST_FRAMEWORK = {
    'DEFAULT_THROTTLE_CLASSES': [
        '[1]',
    ],
    'DEFAULT_THROTTLE_RATES': {
        '[2]': '[3]'
    }
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using permission classes instead of throttle classes in settings.

Mismatching throttle rate keys and classes.

To enable throttling globally, set DEFAULT_THROTTLE_CLASSES to the full path of the throttle class, and define DEFAULT_THROTTLE_RATES with the key matching the throttle scope and the rate string.
