Change rate limit after the app has started

[sandeepkumar-one]

Is it possible to change the rate limit of app or particular route after the app has started?

You should be able to pass a callable that returns a limit string, something like 1/minute, as the limit definition in your decorator, instead of the hardcoded limit string. That function can then return whatever you need on any call. Something like:

def dynamic_limit():
    # do anything you want here
    return "1/minute"

@limiter.limit(dynamic_limit)
async def homepage(request: Request):
    return PlainTextResponse("test")

Let me know if this works for your use case.

Thank you Laurent for explanation. I suggest we add this example in the test case (tests/test_fastapi_extension.py). It will be helpful for others as well.

Sounds good! Feel free to send a PR for this, or to add an example in the docs.

Hi Laurent, I raised a PR : https://github.com/laurentS/slowapi/pull/66 as per above discussion.

I have a doubt, as seen in my PR I am using exempt in this format : @limiter.limit('exempt') rather than @limiter.exempt. If I use the latter I am getting runtime error. Could you please check it once.
