Throttling support?

[ddahan]

What is the recommended way to handle throttling while using Django ninja? I did not find that term in the doc. Is the any plan to use it? Thanks.

@ddahan Hi. FYI #99 I use django-ratelimit

Great, didn't know about this tool. Does it work "as is" with ninja? I mean, can you simply decorate endpoints with @ratelimit(key='ip', rate='5/m') or do you need some tweaks first?

About handling throttling exceptions in Ninja, based on this part of the ratelimit doc, I guess something like this could work:

@api.exception_handler(Ratelimited)
def handle_rate_limited(request, exc):
    # ... handle exception my way

@ddahan @ratelimit(key='ip', rate='5/m') Yes, it work @api.exception_handler(Ratelimited) Yes, I use it too

That'd be a good addition to the docs. Why not write it up as a pull request? ;)

Great idea!

Looks like Does not seem to work with Async APIs

While it's certainly not as elegant as the decorator, you can handle this via usage of django-ratelimit's API's. As an example

from ratelimit.core import is_ratelimited
from ratelimit.exceptions import Ratelimited as RateLimitedError

if is_ratelimited(
    request,
    group="search",
    key="header:X-API-KEY",
    rate="10/s",
    increment=True,
):
   raise RateLimitedError(
       "You have exceeded your quota of requests in an interval.  Please slow down and try again soon."
   )
