"DjangoJSONEncoder" is not defined

  1. Verify that you have imported the necessary module: from django.core.serializers.json import DjangoJSONEncoder
  2. Ensure that the encoding process is calling the encoder correctly: json.dumps(my_data, cls=DjangoJSONEncoder)
  3. If the above steps are correct and the issue persists, consider checking for any typos in the code or potential conflicts with other modules.
