The current [https://docs.djangoproject.com/en/4.0/topics/async/#async-
views topic docs for Async views] say this about class-based views:
> For a class-based view, this means making its __call__() method an async
def (not its __init__() or as_view()).
This isn't really appropriate for Django's class-based views:
* We don't implement `__call__()`, rather going via `as_view() — for a
per-request instance — and then `dispatch()`.
* Users expect to implement the HTTP method handlers — `get`, `post`, and
so on — rather than these ''more internal'' bits.
Ideally we'd allow specifying `async def` at the method handler level, to
allow using `await` in the handler, and writing views such as this:
{{{
import asyncio
from django.http import HttpResponse
from django.views import View
class AsyncView(View):
async def get(self, request, *args, **kwargs):
# Perform io-blocking view-logic using await, sleep for
example.
await asyncio.sleep(1)
return HttpResponse("Hello async world!")
}}}
