Handling Large File Uploads in Django with Async Views
I'm getting frustrated with I'm confused about This might be a silly question, but This might be a silly question, but I'm sure I'm missing something obvious here, but I'm currently working on a Django application (version 4.1) that needs to handle large file uploads efficiently... I've set up an asynchronous view to process uploads, but I'm running into a few issues. My file uploads are timing out, and I'm not sure how to manage the file processing without blocking. Here's a snippet of my view: ```python from django.http import JsonResponse from django.views import View import asyncio class AsyncFileUploadView(View): async def post(self, request): file = request.FILES.get('file') if not file: return JsonResponse({'behavior': 'No file provided.'}, status=400) # Simulating file processing await self.process_file(file) return JsonResponse({'message': 'File uploaded successfully.'}) async def process_file(self, file): # Simulating a long processing task await asyncio.sleep(5) # This is where I simulate processing time # Ideally, I'd save the file here ``` When I test this, I often get a `504 Gateway Timeout` behavior, especially when the file size exceeds 5MB. I've also tried increasing the `DATA_UPLOAD_MAX_MEMORY_SIZE` in my settings, but it doesn't seem to help. I’m using `daphne` as my ASGI server, and I've configured my `nginx` to handle larger bodies, but the timeouts continue. Here’s the relevant part of my `nginx.conf`: ```nginx server { client_max_body_size 20M; } ``` Is there a best practice for handling large file uploads in Django with async views? How can I avoid the timeout errors and ensure efficient processing of large files? Any insights or code examples would be greatly appreciated! I'm working on a CLI tool that needs to handle this. The project is a REST API built with Python. Is there a better approach?
