Select 'Project Interpreter', click on the gearwheel button and select 'Add'. Click the 'Existing environment' radio button to select the virtual environment.

$ flask run

You can use the admin account to access all modules of the system

username: admin

You need to run the server first, it will automatically create a .env file in the project root directory. You can edit the .env file to set the SMTP server. You can find the following configuration items in .env, enter your smtp server related information, and restart the server.

EMAIL_ACCOUNT=''
EMAIL_PASSWORD=''
EMAIL_SENDER_ADDRESS=''
EMAIL_SERVER_HOST=''
EMAIL_SERVER_PORT=587
EMAIL_SERVER_SSL_PORT=465

Celery is an asynchronous task queue, which has better performance as an alternative to email sending in this system. It is highly recommended that you configure celery. For more information, please go in to https://docs.celeryq.dev/en/stable/getting-started/introduction.html

You need to run the server first, it will automatically create a .env file in the project root directory. You can edit the .env file to set Celery. You can find the following configuration items in .env, enter your Celery Broker URL, and restart the server.

You first need to install a suitable cache database (Redis, RabbitMQ, ...) on your computer

CELERY_RESULT_ENGINE_OPTIONS  =  {'echo': True}
CELERY_BROKER_URL=''
CELERY_RESULT_BACKEND=''

You also need to open another terminal (note that the terminal path is also in the project root directory) and enter the following command to start.

• Windows

celery -A celery_worker.celery  worker -l info -P gevent

Sentry is Application Monitoring and Error Tracking Software. Official documentation: https://docs.sentry.io/platforms/python/flask/

You need to run the server first, it will automatically create a .env file in the project root directory. You can edit the .env file to set the Sentry. You can find the following configuration items in .env, enter your Sentry DSN, and restart the server.

SENTRY_DSN=''

Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. It's a pre-fork worker model. The Gunicorn server is broadly compatible with various web frameworks, simply implemented, light on server resources, and fairly speedy.

If you wish to deploy on Linux you can use gunicorn. Official documentation: https://gunicorn.org/

For detailed deployment tutorials, please check: https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-ubuntu-22-04

Our project uses sqlite as the database by default, and sqlite is automatically created when the server is started for the first time. If you wish to deploy this project on a server, we strongly recommend that you use MySQL. You need to run the server first, it will automatically create a .env file in the project root directory. You can edit the .env file to set the database. You can find the following configuration items in .env, enter your database URL, and restart the server.

SQLALCHEMY_DATABASE_URI = 'sqlite:///MTMS.db'  

1. Automatically assigning function

   Automatically assigning function is not part of our project, but it can significantly reduce the tutor/marker coordinator's workload. So we will implement this feature in our future work. While the Hungarian algorithm (https://en.wikipedia.org/wiki/Hungarian_algorithm) can solve this feature after modification.The problem is similar to “n agents, m tasks” assignment problem in combinatorics, except that in our case one marker can mark many courses, and one course can have many markers.According to the students on a course of suitability and preferences, it will automatically match work course and time.

2. Payment Day Email Reminder

   In the future, we will add automatic email reminders system for tutors and markers so that they can submit their workload before payday. The coordinator can set the number of paydays and dates, as well as how many days to send the email in advance.

3. In-site Messaging System

   For a recruitment and administration site, the presence of a messaging system within the site is the icing on the cake, which allows for more accessible communication between students and coordinators. It dramatically simplifies the recruitment steps. In addition, we can also connect it to the email reminder system so that when users are not online, they can receive the reminder email.
