This is a class management application for professors. The students can see a assignment text ant the professor can check the progress of the students for the given assignment. Students can post doubts, the professor is offered a list of waiting groups with doubts so he can answer in a given order.

In order to run the code you need to execute the app.py script with runserver command.

Once the code is running you can go to the deployment address of the system and use it.

Before you'll have to:

1. Install all code dependences specified in requiriments.txt file.
2. Config the DB running the SQL scripts inside MySQL_schema in order to have the schema.
3. Config the DB connection credentials (steps specified in DB section).

1. Logs in.
2. Creates a classroom for a given assignment, with a fixed size, and a given room.
3. It's redirected to a page where the professor can see the seats which students are in which place, the progress in the assignment, the doubts they have, and the solutions to the doubt from the students.

The professor can also upload assignment after be logged in.

1. Logs in.
2. Selects one of the running sessions.
3. Gets the assignment. He can see the different pages, upload doubts and solve doubts from others.

The system it's based on Flask server, it's a microframework python based to serve pages built in the server. Also uses JavaScript and Socket.io to communicate when no refreshing is allowed, well a special version designed to work with flask.

The project uses a structure of folders with a folder for each page or section of pages with common responsibilities.

The various python files under a folder defines the logic estructure and algorithims ClassOn follows. The file structure uses flask blueprints intended to give a better structure to a complex system.

There are two types of user professor and student. The pages they can acess are diferent.

• Professor
  • Home
  • Professor
• Student
  • Home
  • Assignment
  • Student

The decorator @assigment.route() is used to define pages to serve with a defined route, so page refresh is needed.

The decorator @socketio.on() is used to attend to socket events, when is used no page refresh is needed. This functions allows communication between the server an the client dynamically.

The system uses an MySQL database, the libraries are wrote to use MySQL database. In order to migrate to another DB is needed to modify just DBUtils.py.

In order to connect to you DB instance you need a config file inside config folder. You can name the file as you want. For example development.py you will have to fulfill al the fields required with the connection information.

SECRET_KEY = 'your key'
MYSQL_HOST = 'your host'
MYSQL_USER = 'your user'
MYSQL_PASSWORD = 'your pass'
MYSQL_DB = 'my DB instance, just kidding your DB instance'
MYSQL_CURSORCLASS = 'your cursor class'

Check here for more information. And use the command in order to run it for debugging you have to use the command PYTHONUNBUFFERED=1;APP_CONFIG_FILE=C:\*Your Route*\ClassOnV2\BackEnd\Server\config\development.py

If you want to debug the code (in pycharm for example) you'll have to add a new line with DEBUG = True.

The system it's based on Bootstrap 4, which makes the pages generated responsive easily.
