可以使用AIPROMPOM PYTHON更改状态

Question

我需要更改回调中的状态

@dp.callback_query_handler(text="ru", state=States.lang)
async def change_lang_ru(call: types.CallbackQuery, state: FSMContext):
    global menu_keyboard
    async with state.proxy() as data:
        data['lang'] = 'ru'
    await call.answer(text="Язык поменялся", show_alert=True)
    print(States.all())
    await States.menu.set()

实际上没有出现错误，但是下一个状态尚未开始，

INFO:aiogram.contrib.middlewares.logging:Received callback query [ID:1631380781948190838] from user [ID:379835437] for message [ID:123] in chat [private:379835437] with data: ru originally posted by user [ID:5151482169]
INFO:aiogram.contrib.middlewares.logging:Unhandled callback query [ID:1631380781948190838] from user [ID:379835437] for message [ID:123] in chat [private:379835437] with data: ru originally posted by user [ID:5151482169]
INFO:aiogram.contrib.middlewares.logging:Process update [ID:41723130]: [success] (in 6 ms)

这是我下一个状态的开始

@dp.message_handler(state=States.menu)
async def first_test_state_case_met(message: types.Message):
    await message.reply('First!', reply=False)

，这些是我的状态，

class States(StatesGroup):
    lang = State()
    menu = State()

我在文档中找不到任何答案

在你的例子中我有一个错误：

print(States.all())

AttributeError：类型对象“States”没有属性“all”

@dp.callback_query_handler(text="ru", state=States.lang)
async def change_lang_ru(call: types.CallbackQuery, state: FSMContext):
    global menu_keyboard
    async with state.proxy() as data:
        data['lang'] = 'ru'
    await call.answer(text="Язык поменялся", show_alert=True)
    # print(States.all())
    await States.menu.set()

除此之外，所有其他状态都有效，但在 States 更改为菜单状态后：

await States.menu.set()

您应该发送消息以在下一个函数中查看响应，因为您的下一个函数是消息处理程序，因此它需要您发送消息

@dp.message_handler(state=States.menu)
async def first_test_state_case_met(message: types.Message):
    await message.reply('First!', reply=False)

并且不要忘记稍后完成您的状态
