Welcome back! So far, we've learned how to enhance our Django-based To-Do API by adding filtering capabilities. You now know how to filter todo items based on both simple and complex criteria, making your API more powerful and user-friendly.

Today, we will focus on adding sorting capabilities to our To-Do API. Sorting is crucial for making APIs more efficient and user-friendly by allowing users to organize data in meaningful ways. By the end of this lesson, you'll be able to sort your To-Do items based on various fields like priority and task name.

Let's get started!

In the previous lesson, we set up various filters for our Todo model. Though filters are perfectly compatible with sorting, we will omit them for this lesson. This will allow us to focus solely on sorting problems and mastering them before learning to combine them with filtering.

That said, the setup is the same as at the start of the previous lesson: we have a Todo model with fields task, completed, assignee, priority, and group.

To enable sorting, we will use the from the Django REST framework. This filter lets us specify which fields our users can use to sort the data.
