pip install django-telegrambot

Configure your installation

Add django_telegrambot in INSTALLED_APPS

#settings.py

And set your bots:

#settings.py
#Django Telegram Bot settings

DJANGO_TELEGRAMBOT = {

    'MODE' : 'WEBHOOK', #(Optional [str]) # The default value is WEBHOOK,
                        # otherwise you may use 'POLLING'
                        # NB: if use polling you must provide to run
                        # a management command that starts a worker

    'WEBHOOK_SITE' : 'https://mywebsite.com',
    'WEBHOOK_PREFIX' : '/prefix', # (Optional[str]) # If this value is specified,
                                  # a prefix is added to webhook url

    #'WEBHOOK_CERTIFICATE' : 'cert.pem', # If your site use self-signed
                         #certificate, must be set with location of your public key
                         #certificate.(More info at https://core.telegram.org/bots/self-signed )

    'BOTS' : [
        {
           'TOKEN': '123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11', #Your bot token.

           #'ALLOWED_UPDATES':(Optional[list[str]]), # List the types of
                                                   #updates you want your bot to receive. For example, specify
                                                   #``["message", "edited_channel_post", "callback_query"]`` to
                                                   #only receive updates of these types. See ``telegram.Update``
                                                   #for a complete list of available update types.
                                                   #Specify an empty list to receive all updates regardless of type
                                                   #(default). If not specified, the previous setting will be used.
                                                   #Please note that this parameter doesn't affect updates created
                                                   #before the call to the setWebhook, so unwanted updates may be
                                                   #received for a short period of time.

           #'TIMEOUT':(Optional[int|float]), # If this value is specified,
                                   #use it as the read timeout from the server

           #'WEBHOOK_MAX_CONNECTIONS':(Optional[int]), # Maximum allowed number of
                                   #simultaneous HTTPS connections to the webhook for update
                                   #delivery, 1-100. Defaults to 40. Use lower values to limit the
                                   #load on your bot's server, and higher values to increase your
                                   #bot's throughput.

           #'POLL_INTERVAL' : (Optional[float]), # Time to wait between polling updates from Telegram in
                           #seconds. Default is 0.0

           #'POLL_CLEAN':(Optional[bool]), # Whether to clean any pending updates on Telegram servers before
                                   #actually starting to poll. Default is False.

           #'POLL_BOOTSTRAP_RETRIES':(Optional[int]), # Whether the bootstrapping phase of the `Updater`
                                   #will retry on failures on the Telegram server.
                                   #|   < 0 - retry indefinitely
                                   #|     0 - no retries (default)
                                   #|   > 0 - retry up to X times

           #'POLL_READ_LATENCY':(Optional[float|int]), # Grace time in seconds for receiving the reply from
                                   #server. Will be added to the `timeout` value and used as the read timeout from
                           #server (Default: 2).
        },
        #Other bots here with same structure.
    ],

}

Include in your urls.py the django_telegrambot.urls (NB: If you upgrade from a previous version, you MUST change how to include django_telegrambot.urls. Never set prefix here!):

#urls.py
urlpatterns = [
    ...
    url(r'^', include('django_telegrambot.urls')),
    ...
]

Then use it in a project creating a module telegrambot.py in your app

#myapp/telegrambot.py
# Example code for telegrambot.py module
from telegram.ext import CommandHandler, MessageHandler, Filters
from django_telegrambot.apps import DjangoTelegramBot

import logging
logger = logging.getLogger(__name__)


# Define a few command handlers. These usually take the two arguments bot and
# update. Error handlers also receive the raised TelegramError object in error.
def start(bot, update):
    bot.sendMessage(update.message.chat_id, text='Hi!')


def help(bot, update):
    bot.sendMessage(update.message.chat_id, text='Help!')


def echo(bot, update):
    bot.sendMessage(update.message.chat_id, text=update.message.text)


def error(bot, update, error):
    logger.warn('Update "%s" caused error "%s"' % (update, error))


def main():
    logger.info("Loading handlers for telegram bot")

    # Default dispatcher (this is related to the first bot in settings.DJANGO_TELEGRAMBOT['BOTS'])
    dp = DjangoTelegramBot.dispatcher
    # To get Dispatcher related to a specific bot
    # dp = DjangoTelegramBot.getDispatcher('BOT_n_token')     #get by bot token
    # dp = DjangoTelegramBot.getDispatcher('BOT_n_username')  #get by bot username

    # on different commands - answer in Telegram
    dp.add_handler(CommandHandler("start", start))
    dp.add_handler(CommandHandler("help", help))

    # on noncommand i.e message - echo the message on Telegram
    dp.add_handler(MessageHandler([Filters.text], echo))

    # log all errors
    dp.add_error_handler(error)

Features

  • Multiple bots

  • Admin dashboard available at /admin/django-telegrambot

(myenv) $ python runtests.py

Sample Application

There a sample application in sampleproject directory. Here is installation instructions:

  1. Install requirements with command

    pip install -r requirements.txt

  2. Copy file local_settings.sample.py as local_settings.py and edit your bot token

    cp sampleproject/local_settings.sample.py sampleproject/local_settings.py

    nano sampleproject/local_settings.py

  3. Run Django migrations
