Note

The hyphen (-) before the field name indicates that the ordering feature must use descending order instead of the default ascending order.

Make sure you replace 1 with the pk value of the previously retrieved drone category named Quadcopter. The has_it_competed field is a bool field, and therefore, we have to use Python valid bool values (True and False) when specifying the desired values for the bool field in the filter:

http ":8000/drones/?
    drone_category=1&has_it_competed=False&ordering=-name"

The following is the equivalent curl command:

curl -iX GET "localhost:8000/drones/?
    drone_category=1&has_it_competed=False...
