Telegram bot API编辑InlineKeyboard与python-telegram-bot无法正常工作

Question

I'm trying to create a menu where the user can navigate on it. This is my code:

MENU, HELP = range(2)

def start(bot, update):
    keyboard = [
                 [InlineKeyboardButton('Help', callback_data='help')]
               ]

    # Create initial message:
    message = 'Welcome.'

    update.message.reply_text(message, reply_markup=InlineKeyboardMarkup(keyboard))

def help(bot, update):

    keyboard = [
                 [InlineKeyboardButton('Leave', callback_data='cancel')]
               ]


    update.callback_query.edit_message_reply_markup('Help ... help..', reply_markup=InlineKeyboardMarkup(keyboard))

def cancel(bot, update):

    update.message.reply_text('Bye.', reply_markup=ReplyKeyboardRemove())

    return ConversationHandler.END     


# Create the EventHandler and pass it your bot's token.
updater = Updater(token=config.TELEGRAM_API_TOKEN)

# Get the dispatcher to register handlers:
dispatcher = updater.dispatcher

dispatcher.add_handler(CommandHandler('start', start))
dispatcher.add_handler(CallbackQueryHandler(help, pattern='help'))
dispatcher.add_handler(CallbackQueryHandler(cancel, pattern='cancel'))

updater.start_polling()

updater.idle()

As expected, at the /start the user gets the menu 'Help'. When the user clicks on it, the function help() is triggered as expected as well.

Based on my understanding of the python-telegram-bot documentation is was supposed to have the update.callback_query.inline_message_id populated, but its value is None .

I need the update.callback_query.inline_message_id to update my InlineKeyboard menu, right ? Why is the inline_message_id empty (None) ?

Answer 1

I believe there are 2 problems in your code.

First . In your help function, you're trying to change both the text of the message and the markup of it. But the edit_message_reply_markup method only changes the markup . So instead of

update.callback_query.edit_message_reply_markup(
    'Help ... help..',
    reply_markup=InlineKeyboardMarkup(keyboard)
)

Do this:

bot.edit_message_text(
    text='Help ... help..',
    chat_id=update.callback_query.message.chat_id,
    message_id=update.callback_query.message.message_id,
    reply_markup=InlineKeyboardMarkup(keyboard)
)
bot.answer_callback_query(update.callback_query.id, text='')

Notice the changes:

• I replaced update.callback_query with bot .
• IMPORTANT : I replaced edit_message_reply_markup with edit_message_text ; Because the first one only changes the markup , but the second one can do both.
• I added chat_id and message_id arguments; Because that's what it says in the documents .
• IMPORTANT : I added a new method ( bot.answer_callback_query ); Because every time you handle a callback query you need to answer it (using this method). However, you can leave the text argument empty , so that it doesn't show anything.

Second . Correct me if I'm wrong, but I believe when the user presses the cancel button, you want the text of the message to be changed to "Bye." and remove the keyboard . If this is the case, what you're doing wrong is that you're sending a new message ( reply_text ) while trying to remove the keyboard ( reply_markup=ReplyKeyboardRemove() ). You can simply do it like this:

bot.edit_message_text(
    text='Bye',
    chat_id=update.callback_query.message.chat_id,
    message_id=update.callback_query.message.message_id,
)
bot.answer_callback_query(update.callback_query.id, text='')

Here, the idea is that when you edit the text of the message and don't use a markup keyboard, the previous keyboard gets automatically removed , so you don't need to use ReplyKeyboardRemove() .
