Django - Async Django

Given this async middleware snippet, what will be printed when a request is processed?

class LogMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    async def __call__(self, request):
        print('Before response')
        response = await self.get_response(request)
        print('After response')
        return response

ANo output printed due to async

BOnly Before response printed, then returns

COnly After response printed, then returns

DBefore response printed, then After response printed after response

Step-by-Step Solution

Solution:

Step 1: Analyze print statements order
The middleware prints 'Before response' before awaiting the response, then prints 'After response' after awaiting.
Step 2: Understand async call flow
Await pauses until response is ready, so both prints happen in order around the response.
Final Answer:
Before response printed, then After response printed after response -> Option D
Quick Check:
Print before and after await = Before response printed, then After response printed after response [OK]

Quick Trick: Print before and after await shows both messages in order [OK]

Common Mistakes:

MISTAKES

Thinking async prevents print output
Assuming only one print runs
Confusing order of prints around await
