Summary
In this chapter, we learned how to tackle the problem of long-running tasks using Celery. In web development, having a long-running task is quite common, such as when we have to generate a monthly report, send an email to a batch of users, process data from an uploaded file, and so on. Celery is very handy to address such use cases. Similarly, there are plenty of use cases where you need task-scheduling functionality. For example, if we wanted to send a weekly consolidated report to users every week, send reminder emails to end users, and so on, celery beat would be our go-to tool to build such features.
In Chapter 9, we will learn how to write unit and integration tests with Django. Writing unit tests is one of the most important yet frequently overlooked phase in the development cycle. We will learn all the best practices to follow while writing unit and integration tests.
