Help with logic in routers

[xahys]

Hi all!

I'm trying to write a bot that includes different functionality.
I really like the idea of ​​using routers, but I am stucked by following problem:
RuntimeError: Router is already attached to <Router '0x208fa008090'>

Therefore, I think that at one moment I do not correctly exit the router, because I do not know the mechanism - it is not described anywhere. And is it generally possible to detach the router session?

I'm jun in python, and even more so just to know aiogram. I can make mistakes, and I will be glad to any comments and critic.

tree of work directory

.
├── bot.py
└── routers/
    ├── bot_workstart
    ├── bot_worktype
    ├── bot_type1
    └── bot_type2

bot.py

from config_reader import config
import asyncio
import logging
from aiogram import Bot, Dispatcher, types
from aiogram.filters.command import Command

async def main():
    bot = Bot(token=config.bot_token.get_secret_value())
    dp = Dispatcher()

    logging.basicConfig(level=logging.INFO)

    dp.include_router(bot_workstart.router)

    await bot.delete_webhook(drop_pending_updates=True)
    await dp.start_polling(bot)

if __name__ == "__main__":
    asyncio.run(main())

bot_workstart

from aiogram import Router
from aiogram.filters import Command
from aiogram.types import Message

from keyboards.work_keyb import keyboard_work_start
from . import worktype

router = Router()

@router.message(Command("release"))  
async def work_start(message: Message):
    print('Step 1')
    if message.chat.username == 'myuser' or message.from_user.username == 'myuser':
        await message.answer(
            "Please choose type of work",
            reply_markup=keyboard_work_start()
            router.include_router(worktype.router1)
            router.include_router(worktype.router2)
        )
    else:
        await message.answer("Your a not authorized person")

bot _worktype

from aiogram import Router
from aiogram.filters.text import Text
from aiogram.types import Message

from keyboards.work_keyb import keyboard_rel_start_end, keyboard_inf_start_end

from . import bot_type1, bot_type2

router1 = Router()
router2 = Router()

@router1.message(Text("release"))
async def release_start(message: Message):
    print('Step 2 - type1')
    if message.chat.username == 'myuser' or message.from_user.username == 'myuser':
        await message.answer(
            "Choose type",
            reply_markup=keyboard_rel_start_end()
        )
    else:
        await message.answer("Your a not authorized person")

    router1.include_router(bot_type1.routerrelease)


@router2.message(Text("infra"))
async def release_start(message: Message):
    print('Step 2 - type2')
    if message.chat.username == 'myuser' or message.from_user.username == 'myuser':
        await message.answer(
            "Choose type",
            reply_markup=keyboard_inf_start_end()
        )
    else:
        await message.answer("Your a not authorized person")

    router2.include_router(bot_type2.routerinfra)

So in log when i start bot i get messages like this:

INFO:aiogram.dispatcher:Start polling
INFO:aiogram.dispatcher:Run polling for bot @testbot id=12345- 'testbot'
Step 1 # pressed command release
INFO:aiogram.event:Update id=486589035 is handled. Duration 202 ms by bot id=6381341905

######### At this time i choose different button :"infra"
ERROR:aiogram.event:Cause exception while process update id=486589038 by bot id=6381341905
RuntimeError: Router is already attached to <Router '0x244e8c14590'>

I did this and noticed that during the bot's operation only the router that I first select when choosing by keyboard choosing

Therefore, I created this topic, in order to find out if it is possible to reset the router during the session or detach active router...

It looks like you're trying to pull an owl onto a globe - trying to use routers registering mechanist just like FSM, so, please, read the docs about FSM: https://docs.aiogram.dev/en/dev-3.x/dispatcher/finite_state_machine/index.html

Note that you should'nt register any handler or router after you start receiveng of the incoming events. All handlers in routers tree should be registered when you construct the application.
