AttributeError: 'Updater' object has no attribute 'dispatcher'
Question:
When I run this code:
from telegram.ext import *
import keys
print('Starting a bot....')
def start_commmand(update, context):
update.message.reply_text('Hello! Welcome To Store!')
if __name__ == '__main__':
updater = Updater(keys.token, True)
dp = updater.dispatcher
# Commands
dp.add.handler(CommandHandler('start', start_commmand))
# Run bot
updater.start_polling(1.0)
updater.idle()
I get this error:
Traceback (most recent call last):
File "C:UserspcPycharmProjectstelegrammain.py", line 11, in <module>
dp = updater.dispatcher
AttributeError: 'Updater' object has no attribute 'dispatcher'
I attempted to resolve this issue by updating the library but the error remained.
Answers:
You probably found an example for v13, but since a few days the v20 for python-telegram-bot is out. Now you have to build your application differently and you have to use async functions.
This should work:
from telegram.ext import *
import keys
print('Starting a bot....')
async def start_commmand(update, context):
await update.message.reply_text('Hello! Welcome To Store!')
if __name__ == '__main__':
application = Application.builder().token(keys.token).build()
# Commands
application.add_handler(CommandHandler('start', start_commmand))
# Run bot
application.run_polling(1.0)
Also, here are some good examples for the python-telegram-bot library.
Check recent changelogs I found a bug fix for versions >= 20.0a0 where dispatcher is no longer used, but if you want to run your script in that version you need to install it pip install python-telegram-bot==13.3
from telegram import Update, ForceReply
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters, CallbackContext
def start(update: Update, _: CallbackContext) -> None:
user = update.effective_user
update.message.reply_markdown_v2(
fr'Hi {user.mention_markdown_v2()}!',
reply_markup=ForceReply(selective=True),
)
def help_command(update: Update, _: CallbackContext) -> None:
update.message.reply_text('Help!')
def run_bot(update: Update, _: CallbackContext) -> None:
replica = update.message.text
answer = bot(replica)
update.message.reply_text(answer)
print(replica)
print(answer)
print()
def main() -> None:
updater = Updater("token")
dispatcher = updater.dispatcher
dispatcher.add_handler(CommandHandler("start", start))
dispatcher.add_handler(CommandHandler("help", help_command))
dispatcher.add_handler(MessageHandler(Filters.text & ~Filters.command, run_bot))
# Initialize bot
updater.start_polling()
updater.idle()
main()
