This repository contains the example code for a contact API project, using SQLAlchemy, PyTest, Celery with Flask.

• Model a Contact with username, email, first name and surname.
• Create a Restful API that returns a list of all contacts.
• Returns a contact by username.
• Saves a Contact.
• Updates a Contact
• Deletes a Contact
• Allow a contact to have multiple email addresses. Adjust GET, POST, PUT, DEL methods to the new sub entity.
• Extend the GET to also accept the email address for contact retrieval.
• Implement a celery task to create a random contact with two email addresses every 15 seconds. Any older entries then 1 min should be cleaned up and deleted.
