Telegram bot

The telegram bot is using the quiz foundation and it has three main functions: - creating a quiz, - attempt a quiz, - edit data at database.

Every one of them uses a ConversationHandler and their way to work is specified in: - bot.create_quiz.py, - bot.attempt_quiz.py, - bot.edit_quiz.py.

The best way to show their way to work is by using an automata diagram. You can cancel the process during the creation and attempt like in the renaming and removing process.

"Create quiz" automata — The automata of the process to create a new quiz

"Attempt quiz" automata — The automata of the process to attempt to a quiz

"Rename" automata — The automata of the process to rename an existing quiz

"Remove" automata — The automata of the process to remove an existing quiz

The rename- and remove-process takes place in bot.edit_quiz.py. Saving, loading, renaming and deleting a quiz works with PostgreSQL (via SQLAlchemy). Schema migrations are managed by Alembic.
