django: отображение ошибок базы данных при отладке = False

0 голосов
/ 20 марта 2019

Я использую Django Rest Framework для выполнения get () post () в существующей базе данных.В моделях я не определил никаких отношений первичного или внешнего ключа, так как эти ограничения обрабатываются на уровне базы данных.Когда у меня есть debug = True в файле settings.py, отображаются ошибки уровня базы данных с трассировкой.Однако, когда debug = False, я хочу отобразить ошибки в ответе.

Например: сообщение об ошибке: 

IntegrityError at /dqf_api/ReceiptLog/
(1062, "Duplicate entry 'ede pivot-dummy-ede_case_76-ede pivot command 76' for key 'PRIMARY'")

Когда debug = True, это отображается.Когда debug = False, как мне отловить эту ошибку и отобразить ее?

EDIT : включая модули кода

РЕДАКТИРОВАТЬ: код исправления

Добавил это в serializers.py 

def create(self, validated_data):
    try:
        return super().create(validated_data)
    except IntegrityError as e:
        error_msg = "IntegrityError occurred while creating entry in test_case_command_run_result model. Detailed Error: %s" %e
        raise serializers.ValidationError(error_msg)

Может быть попробовать что-то вроде этого: 

if serializer.is_valid():
    serializer.save()
    return Response("success")
else:
    return Response(serialzier.errors)

Использование оператора try catch
В views.py 

class TestCaseCommandRunViewSet(viewsets.ModelViewSet):
    try:
        queryset = models.TestCaseCommandRunViewSet.objects.values('team_name','suite_name','suite_run_id', 'case_name','command_name','command_run_id','run_start','run_end','result','run_status')
