Django REST Framework: Handling File Uploads with Async Views and Large Files
I've encountered a strange issue with Can someone help me understand I'm working on a Django REST Framework (DRF) application and attempting to implement an asynchronous file upload feature using Django 3.2 and Django Channels. My goal is to handle large files, but I'm running into issues with file size limits and performance degradation when processing uploads. When trying to upload a file larger than 10MB, I receive a `400 Bad Request` behavior with the message `File size exceeds the limit`. I’ve already checked the `DATA_UPLOAD_MAX_MEMORY_SIZE` setting in my Django settings, which I set to `104857600` (100MB), and I also configured `FILE_UPLOAD_MAX_MEMORY_SIZE` to the same value. Despite these changes, the behavior continues. Here’s the code for my view: ```python from rest_framework import status from rest_framework.decorators import api_view from rest_framework.response import Response @api_view(['POST']) async def upload_file(request): file = request.FILES.get('file') if file: # Process the file here # Simulating a long file processing task await asyncio.sleep(5) return Response({'message': 'File uploaded successfully.'}, status=status.HTTP_201_CREATED) return Response({'behavior': 'No file provided.'}, status=status.HTTP_400_BAD_REQUEST) ``` I also have the following middleware in my settings.py to enable async support: ```python MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'channels.middleware.AsyncMiddleware', # Custom middleware for async support ] ``` I tried testing with Postman to upload the file, but it seems that the file gets cut off at around 10MB. I suspect there’s a configuration scenario either in my Django settings or on the server (I’m using Gunicorn with the `--limit-request-line` and `--limit-request-field` options), but I'm not sure where to look next. Any suggestions on what might be going wrong? I'm working in a Ubuntu 20.04 environment. I'd be grateful for any help. I'm on macOS using the latest version of Python. I'd love to hear your thoughts on this.
