ownbot

Easy to use python module to create private telegram bots using python-telegram-bot.

Ownbot provides some cool decorators to protect your command handler functions from unauthorized users!

Install

pip install ownbot

Get Started

Simply add the requires_usergroup decorator to your handler function! That's it!

from ownbot.auth import requires_usergroup, assign_first_to
(...)

@assign_first_to("admin")
@requires_usergroup("user")
def start_handler(bot, update):
    bot.sendMessage(chat_id=update.message.chat_id, text="Hello World")

• The assign_first_to decorator adds the first user who invokes the handler method to the specified group.
• The second decorator requires_usergroup lets you define which usergroups will have permission to access the handler command.

Obviously admin users have access to all protected commands. If a group passed to the requires_usergroup decorator does not already exist, it will be created.

How It Works

Ownbot saves new users added by Telegram username as unverified users. On first contact, when the user sends his first message to the bot, ownbot will store the user with his unique id as a verified user. A verified user will from now on always have access to his group even if he changes his username. The authorization checks are done only on the unique Telegram user_id! Sounds good right?

Storage

For user/group storage ownbot uses a simple yaml file, which can be found in $HOMEDIR/.ownbot/users.yml. This file can be edited manually, but it is recommended to use the AdminCommands to add or remove users from groups.

Admin Commands

The admin commands can be enabled by simply instantiating the AdminCommands class and passing over the bot's dispatcher.

from ownbot.admincommands import AdminCommands
(...)
updater = Updater(TOKEN)
dispatcher = updater.dispatcher
AdminCommands(dispatcher)

If the admin commands are enabled, a user who is in the admin group is able to perform the following actions:

Command	Arguments	Description
/adminhelp	-	Shows a list of available commands.
/users	-	Shows a list of all registered users.
/adduser	user group	Adds a user to a group.
/rmuser	user group	Removes a user from a group.
