Comment (by Carlton Gibson):
#34271 was a duplicate with a suggestion to make the cache key just depend
on the request path:
{{{
from pathlib import Path
from django.conf import settings
from django.core.cache import caches
default_cache = caches[settings.CACHE_MIDDLEWARE_ALIAS]
cache_key = ".".join(Path(request.path[1:]).parts)
if not (response := default_cache.get(cache_key)):
response = view_func(request, *args, **kwargs)
response.add_post_render_callback(
lambda r: default_cache.set(cache_key, r, timeout)
)
}}}
That would be easy to invalidate outside the request context.
Allowing/documenting easier make_key customisation might allow us to move
this forward? 🤔
