Middleware Initialization with Settings - Hari's Configuration Scenario

from django.conf import settings

class ConfigurableMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response
        self.secret_key = getattr(settings, 'CUSTOM_SECRET_KEY', 'default')
        self.enabled = getattr(settings, 'MIDDLEWARE_ENABLED', True)

    def __call__(self, request):
        if not self.enabled:
            return self.get_response(request)
        request.secret = self.secret_key
        return self.get_response(request)

  1. The middleware correctly reads settings with defaults and conditionally processes requests

  2. Settings should be accessed in __call__ method, not in __init__

  3. Using getattr with defaults is unsafe and all settings must be explicitly defined

  4. Middleware cannot access Django settings from django.conf module

Show answer & explanation

Correct answer

The middleware correctly reads settings with defaults and conditionally processes requests

Explanation

The middleware reads configuration from Django settings during initialization using getattr with defaults, allowing flexible configuration and graceful degradation when settings are missing.
