update the date from the serializer with a new dict

[georgen...@gmail.com]

I have created a simple service which returns the data from a single table based on a param in the URL as follow:

Enter code here...http://127.0.0.1:8000/api/figo?figonr=1078924300-01

output is the json:
HTTP 200 OK
Allow: GET
Content-Type: application/json
Vary: Accept

[
   {
        "figonr": "1078924300-01",
        "description": "F150/C+W/CC/GE201S/S/OE/SE",
        "productgroup": null
   }
]

I would like to add in the json list a small dict with values like

Enter code here...{

"execution_time": "13:00"
}

so the final result will be

Enter code here...[

    {
    "figonr": "1078924300-01",
    "description": "F150/C+W/CC/GE201S/S/OE/SE",
    "productgroup": null
    },
    {
    "execution_time": "13:00"
    }
]

here is my serilalizer code

Enter code here...from rest_framework import serializers

from servicesapp.models import Figo
import datetime

class ServiceAppSerializer(serializers.ModelSerializer):
    ExecutionTime = serializers.SerializerMethodField()  # add field

    class Meta:
        model = Figo
        fields=('figonr','description', 'username', 'timestmp', 'ExecutionTime')

    def get_ExecutionTime(self, obj):
        # here write the logic to compute the value based on object
        george=1
        return datetime.datetime.now()
