The bot fetches data from Hemnet.se ads and sends to Telegram chat for historical purposes.

Prerequisites

• create MongoDB cluster;
• create bot user via BotFather and get API token;
• create Telegraph token (use function create_account() from app/telegraph_functions.py: python -c 'import telegraph_functions; print(telegraph_functions.create_account("some_account"))')
• Docker.

Run the bot in Docker container

Environment variables

Before you run the container, you need to prepare several environment variables and put them to file .env:

Variable	Description	Default
TELEGRAM_BOT_TOKEN	API token that BotFather gives you when you create a bot	-
TELEGRAPH_TOKEN	Token to access telegraph	-
ADMIN_CHAT_ID	Chat ID of a user that gets log messages	-
CHAT_ID	Group chat the bot will send messages to	-
MONGO_CONNECTION_STRING	Connection string to Mongo cluster	-
PAGE_URL	Hemnet.se search URL	-

The file will look like this:

TELEGRAM_BOT_TOKEN=...
TELEGRAPH_TOKEN=...
ADMIN_CHAT_ID=...
CHAT_ID=...
MONGO_CONNECTION_STRING="..."
PAGE_URL=...

In order to get CHAT_ID of a group chat

1. Add your bot to the group.
2. Tag him in a message, i.e. Hello @hemnet_parser_bot
3. Call getUpdates for your bot: curl https://api.telegram.org/bot<TELEGRAM_BOT_TOKEN>/getUpdates and look for the chat item in the returned dictionary.

Start the container

$ docker-compose up -d
