A simple app to develop Telegram bots with Django
The full documentation is at https://django-telegrambot.readthedocs.org.
If this project help you reduce time to develop, you can give me a cup of coffee :)
- IMPORTANT ver 1.0.0 : If you upgrade from a previous version, you MUST change how to include
django_telegrambot.urlsand modify yoursettings.py.
Install django-telegrambot:
pip install django-telegrambot
Add django_telegrambot in INSTALLED_APPS
#settings.py
INSTALLED_APPS = (
...
'django_telegrambot',
...
)
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 )
'STRICT_INIT': True, # If set to True, the server will fail to start if some of the
# apps contain telegrambot.py files that cannot be successfully
# imported.
'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.
# 'MESSAGEQUEUE_ENABLED':(Optinal[bool]), # Make this True if you want to use messagequeue
# 'MESSAGEQUEUE_ALL_BURST_LIMIT':(Optional[int]), # If not provided 29 is the default value
# 'MESSAGEQUEUE_ALL_TIME_LIMIT_MS':(Optional[int]), # If not provided 1024 is the default value
# 'MESSAGEQUEUE_REQUEST_CON_POOL_SIZE':(Optional[int]), # If not provided 8 is the default value
#'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)
Multiple bots
Admin dashboard available at

pip install -r requirements.txt
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
