Feature request: Attach information about rate-limit violations to request object for use in custom middleware

[ThomasAitken]

i.e. something like a change to core.is_ratelimited as follows:

def is_ratelimited(request, group=None, fn=None, key=None, rate=None, method=ratelimit.ALL, increment=False):
    usage = ratelimit.core.get_usage(request, group, fn, key, rate, method, increment)
    if usage is None:
        return False

    # patching begins... attaching the key data to the request object
    if usage["should_limit"]:
        request.django_ratelimit_data = {
            "group": group,
            "fn_name": fn.__name__ if fn is not None else None,
            "count": usage["count"],
            "limit": usage["limit"],
        }
    return usage["should_limit"]

Is there any reason why you didn't do this? It would help a lot for logging and figuring out what's actually going on with users.
