Composing requests that filter and order results


We will compose and send an HTTP request to retrieve all the drones whose related drone category ID is equal to 1 and whose value for the has_it_competed field is equal to False. The results must be sorted by name in descending order, and therefore, we specify -name as the value for the ordering query parameter.

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...
