Is it possible with the python-telegram-bot wrapper to use more than one callback query handler?
I would like to have multiple unique handlers but as far as I can tell, there can only be one. This means I'd have to base which inline keyboards I show on the initiating message text.
Is there something I'm missing?
You can use ConversationHandler wrapper for that. Check code bellow:
from telegram import InlineKeyboardButton, InlineKeyboardMarkup
from telegram.ext import Updater, CommandHandler, CallbackQueryHandler, ConversationHandler
TELEGRAM_HTTP_API_TOKEN = 'PASTE_TELEGRAM_HTTP_API_TOKEN'
FIRST, SECOND = range(2)
def start(bot, update):
keyboard = [
[InlineKeyboardButton(u"Next", callback_data=str(FIRST))]
]
reply_markup = InlineKeyboardMarkup(keyboard)
update.message.reply_text(
u"Start handler, Press next",
reply_markup=reply_markup
)
return FIRST
def first(bot, update):
query = update.callback_query
keyboard = [
[InlineKeyboardButton(u"Next", callback_data=str(SECOND))]
]
reply_markup = InlineKeyboardMarkup(keyboard)
bot.edit_message_text(
chat_id=query.message.chat_id,
message_id=query.message.message_id,
text=u"First CallbackQueryHandler, Press next"
)
reply_markup = InlineKeyboardMarkup(keyboard)
bot.edit_message_reply_markup(
chat_id=query.message.chat_id,
message_id=query.message.message_id,
reply_markup=reply_markup
)
return SECOND
def second(bot, update):
query = update.callback_query
bot.edit_message_text(
chat_id=query.message.chat_id,
message_id=query.message.message_id,
text=u"Second CallbackQueryHandler"
)
return
updater = Updater(TELEGRAM_HTTP_API_TOKEN)
conv_handler = ConversationHandler(
entry_points=[CommandHandler('start', start)],
states={
FIRST: [CallbackQueryHandler(first)],
SECOND: [CallbackQueryHandler(second)]
},
fallbacks=[CommandHandler('start', start)]
)
updater.dispatcher.add_handler(conv_handler)
updater.start_polling()
updater.idle()
