===========
|
||
|
|
|
||
|
|
Base handler is generic abstract class and should be used in all other class-based handlers.
|
||
|
|
|
||
|
|
Import: :code:`from aiogram.hanler import BaseHandler`
|
||
|
|
|
||
|
|
By default you will need to override only method :code:`async def handle(self) -> Any: ...`
|
||
|
|
|
||
|
|
This class is also have an default initializer and you don't need to change it.
|
||
|
|
Initializer accepts current event and all contextual data and which
|
||
|
|
can be accessed from the handler through attributes: :code:`event: TelegramEvent` and :code:`data: Dict[Any, str]`
|
||
|
|
|
||
|
|
If instance of the bot is specified in context data or current context it can be accessed through *bot* class attribute.
