SynchronousOnlyOperation: async usage in sync context

SynchronousOnlyOperation: async in sync

$ python - <<'PY'
import asyncio
async def a(): return 1
try:
    a()
except Exception as e:
    print(type(e).__name__, e)
PY
RuntimeWarning coroutine 'a' was never awaited

Why this happens

You invoked async ORM or async functions directly in a sync view.

Fix

Use async def views with ASGI or wrap with async_to_sync where appropriate.

Wrong code

result = async_func()

Fixed code

from asgiref.sync import async_to_sync
result = async_to_sync(async_func)()
