Defining the requirements for a complex RESTful Web Service

So far, our RESTful Web Service performed CRUD operations on a single database table. Now, we want to create a more complex RESTful Web Service with the Django REST framework to interact with a complex database model.

A drone is an IoT (short for Internet of Things) device that interacts with many sensors and actuators, including digital electronic speed controllers linked to engines, propellers, and sensors. A drone is also known as an Unnamed Aerial Vehicle (UAV). We will code a RESTful Web Service that will allow us to register competitions for drones that are grouped into drone categories. In our previous RESTful Web Service, we had toys grouped in toy categories and we used a string field to specify the toy category for a toy. In this case, we want to be able to easily retrieve all the drones that belong to a specific drone category. Thus, we will have a relationship between a drone and a drone category.
