This commit introduces a comprehensive database schema and implements a new user registration validation system.
1. **New Database Documentation (`db_tasks.md`):**
* Creates a new `db_tasks.md` file to document the full database schema.
* Defines detailed tables for `users` (with vacation balance tracking), `vacations`, and `permission_requests` to serve as a robust HR management system.
2. **User Registration Validation:**
* Removes the previous user validation logic that relied on Google Sheets.
* Adds a new `FullHRData` SQLAlchemy model that maps to the `vanessa_logs.full_HRdata` table.
* Implements a `check_user_registration` function in `modules/database.py` to verify if a user's `telegram_chat_id` already exists in the database.
* Integrates this check into the `/welcome` command in `modules/onboarding.py`. The bot now blocks already-registered users with a specific error message, as requested.
- Add a check to see if a user's Telegram chat ID already exists in a Google Sheet.
- If the user is already registered, the 'welcome' option is hidden from the main menu.
- Added gspread and google-auth-oauthlib to requirements.txt.
- Modified database.py to support Google Service Account credentials from environment variables.
- Updated .env.example with the new environment variables.
This commit introduces Docker and Docker Compose to containerize the application and orchestrate it with a MySQL database.
Key changes include:
- Added a `Dockerfile` to create a container for the Python bot.
- Created a `docker-compose.yml` file to manage the bot and MySQL services.
- Added a `modules/database.py` module to handle database connections and logging with SQLAlchemy.
- Integrated request logging into all command handlers.
- Updated `requirements.txt` with necessary dependencies for MySQL.
- Updated `.env` and `.gitignore` to manage database credentials securely.
- Updated `Readme.md` with instructions on how to run the application using Docker Compose.
