Setting up a local instance

If you want to test the bot by creating your personal instance, follow this steps:

• Clone this repository or download it as zip.
• Send a message to your bot on Telegram, even '/start' will do. If you don't, you could get an error
• Make a copy of the file "data/DMI_DB.db.dist" in the same directory and rename it to "DMI_DB.db" to enable the database sqlite
• Make a copy of the file "config/settings.yaml.dist" in the same directory and rename it to "settings.yaml" (If you don't have a token, message Telegram's @BotFather to create a bot and get a token for it)
• Now you can launch "main.py" with your Python3 interpreter

System requirements

• Python 3
• python-pip3
• language-pack-it
• libqtwebkit (v5)

To install with pip3

• python-telegram-bot==12.8

Known problems on Ubuntu 20.04:

• Installing libqtwebkit

Open terminal in your repo folder and run command:

After adding the PPA, it should automatically refresh the system package cache. If not, you may run command to manually update the package cache:

sudo apt update

• Installing dryscrape

Download webkit-server from github:

git clone https://github.com/niklasb/webkit-server.git webkit-server

Change in webkit-server/setup.py :

shutil.copy('src/webkit_server', self.build_purelib)
shutil.copy('src/webkit_server', self.build_platlib)

to

shutil.copy('src/webkit_server.pro', self.build_purelib)
shutil.copy('src/webkit_server.pro', self.build_platlib)

then run:

cd webkit-server
python setup.py install

• There you go!

Special functions

Notes: only some users are allowed to use these commands indeed there is an if condition that check the chatid of the user that can use them

- /stats

You can enable these commands setting disable_db = 0 and copy data/DMI_DB.db.dist into data/DMI_DB.db

This command shows the statistics of the times where the commands are used in the last 30 days.

- /drive /request /adddb

You can enable these commands setting disable_drive = 0, configure the GoogleDrive credentials and copy data/DMI_DB.db.dist into data/DMI_DB.db.

/drive: command to get the GoogleDrive files /request allows the user to send the subscribe request to get the access for /drive /adddb allows some special users to give the access to /drive to another user

Configure Drive

• open a project on the Google Console Developer
• enable Drive API
• download the drive_credentials.json and put it on config/
• copy config/settings.yaml.dist into config/settings.yaml, then configure it

Docker container

How to use

Build image dmibot with docker:

$ docker build ./ -t dmibot --build-arg TOKEN=<token_API>

Run the container dmibot:

$ docker run -it dmibot

Now you can go to the dmibot directory and run the bot:

$ cd /usr/local/dmibot/
$ python main.py

Note: if you need to run the main.py in a VPS, you will need now xvfb-run to run it (xvfb-run python3 main.py), because dryscrape requires it.

Testing

To install with pip3

• pytest
• pytest-asyncio
• telethon

To install all the test requirements you can run:

pip3 install -r test-requirements.txt

Steps:

• # your Telegram account with your phone number here. Then choose “API development tools”
• If it is your first time doing so, it will ask you for an app name and a short name, you can change both of them later if you need to. Submit the form when you have completed it
• You will then see the api_id and api_hash for your app. These are unique to your app, and not revocable.
• Edit the folling values in the config/settings.yaml file:

test: 
  api_hash: hash of the telegram app used for testing
  api_id: id of the telegram app used for testing
  session: session of the telegram app used for testing (see steps below)
  tag: tag of the bot used for testing
  token: token for the bot used for testing
  representatives_group: representatives' group id used for testing
  dev_group_chatid: dev's group id used for testing

• Copy the file "tests/conftest.py" in the root folder and Run

python3 conftest.py .

• Follow the procedure and copy the session value it provides in the settings file in "test:session". You can then delete the "conftest.py" you just used, you won't need it again
• Edit the remaining values in the settings file as you like
