Django 4.1: Issues with Async Views and Database Queries in a Custom Middleware
I'm writing unit tests and I'm updating my dependencies and I'm stuck on something that should probably be simple... Quick question that's been bugging me - I'm currently developing a Django 4.1 application that relies on async views and I've run into a problem with a custom middleware that performs database queries... The middleware is supposed to log user actions asynchronously but I noticed that when I try to access the database, I get the following error: `RuntimeError: This event loop is already running`. Here’s a snippet of the middleware: ```python from django.utils.deprecation import MiddlewareMixin import asyncio from myapp.models import UserAction class AsyncLogMiddleware(MiddlewareMixin): async def __call__(self, request): response = await super().__call__(request) await self.log_user_action(request.user) return response async def log_user_action(self, user): action = UserAction(user=user, action='accessed page') await action.save() ``` I’ve tried a few different approaches to resolve the error. First, I ensured that Django's `ASGI` server is set up correctly, and I switched to using `async def` in my middleware. I also attempted to wrap the `save()` method in `asyncio.run()`, but it led to another error: `RuntimeError: Event loop is closed`. I’ve confirmed that the database is set up for async queries and I’m using `django.db.async` for my models. Could someone help me understand how to properly handle async database operations within my middleware? Is there a more suitable way to log user actions without causing event loop issues? I appreciate any insights! What's the correct way to implement this?
