Callback answer#

Helper for callback query handlers, can be useful in bots with a lot of callback handlers to automatically take answer to all requests.

Simple usage#

For use, it is enough to register the inner middleware aiogram.utils.callback_answer.CallbackAnswerMiddleware in dispatcher or specific router:

dispatcher.callback_query.middleware(CallbackAnswerMiddleware())

After that all handled callback queries will be answered automatically after processing the handler.

Advanced usage#

In some cases you need to have some non-standard response parameters, this can be done in several ways:

Global defaults#

Change default parameters while initializing middleware, for example change answer to pre mode and text «OK»:

dispatcher.callback_query.middleware(CallbackAnswerMiddleware(pre=True, text="OK"))

Look at aiogram.utils.callback_answer.CallbackAnswerMiddleware to get all available parameters

Handler specific#

By using flags you can change the behavior for specific handler

@router.callback_query(<filters>)
@flags.callback_answer(text="Thanks", cache_time=30)
async def my_handler(query: CallbackQuery):
    ...

Flag arguments is the same as in aiogram.utils.callback_answer.CallbackAnswerMiddleware with additional one disabled to disable answer.

A special case#

It is not always correct to answer the same in every case, so there is an option to change the answer inside the handler. You can get an instance of aiogram.utils.callback_answer.CallbackAnswer object inside handler and change whatever you want.

Небезпека

Note that is impossible to change callback answer attributes when you use pre=True mode.

@router.callback_query(<filters>)
async def my_handler(query: CallbackQuery, callback_answer: CallbackAnswer):
    ...
    if <everything is ok>:
        callback_answer.text = "All is ok"
    else:
        callback_answer.text = "Something wrong"
        callback_answer.cache_time = 10

Combine that all at once#

For example you want to answer in most of cases before handler with text «🤔» but at some cases need to answer after the handler with custom text, so you can do it:

dispatcher.callback_query.middleware(CallbackAnswerMiddleware(pre=True, text="🤔"))

@router.callback_query(<filters>)
@flags.callback_answer(pre=False, cache_time=30)
async def my_handler(query: CallbackQuery):
    ...
    if <everything is ok>:
        callback_answer.text = "All is ok"

Description of objects#

Bases: BaseMiddleware

__init__(pre: bool = False, text: str | None = None, show_alert: bool | None = None, url: str | None = None, cache_time: int | None = None) → None[source]#
