Celery is a popular distributed tasks queue. It is often used with Django framework to process heavy computational tasks in the background. You can add a single task to the queue or define periodic tasks. Periodic tasks are automatically scheduled for execution based on set time. The most common approach is to define the periodic tasks before the Celery worker is started. For example, it can be daily cleaning of the database. What if we would like to define periodic tasks dynamically? Recently, I’ve been working on a web app for uptime monitoring. The service continuously monitors a server and send email notification when the server is down. In the web app, the user can add a server address to be monitored and select the interval between requests to the server. How to dynamically add periodic tasks in Celery? I want to describe my approach in this article.

Django Rest Framework Email Verification
Django-rest-framework Backend Boilerplate Email Piotr Płoński, December 23, 2020
Email verification is an important part of the SaaS application. We will contact the user by email in many cases: for a password reset, announcement of new features, or for sending the invoice. During registration, a user provides the email address. We need to check if the email belongs to the user and that there are no typos/errors in it. This can be easily done by automatically sending the verification email with an activation link. Such a link contains the unique token assigned to the user. After opening the activation link in the web browser, the request is sent to the web application (Django Rest Framework). The web server compares the token from the activation URL with the token stored in the database. If they are the same, the email address is verified.
