django: Displaying database errors when debug = False - django

Question

I am using Django Rest Framework to perform get() post() on existing database. In the models, I haven't defined any primary or foreign key relations as these constraints are handled at database level. When I have debug = True in the settings.py file, the database level errors with traceback get displayed. However, when debug = False, I wish to display the errors in the response.
eg: error message:
IntegrityError at /dqf_api/ReceiptLog/
(1062, "Duplicate entry 'ede pivot-dummy-ede_case_76-ede pivot command 76' for key 'PRIMARY'")
When debug = True, this is displayed. When debug = False, how do I catch this error and display it?

urls.py
router = routers.DefaultRouter()
router.register(r'test_case_command_runs', views.TestCaseCommandRunViewSet)
router.register(r'test_case_command_run_results', views.TestCaseCommandRunResultsViewSet)
urlpatterns = [
url(r'^dqf_api/', include(router.urls)),
url(r'^dqf_api/ReceiptLog/', views.ReceiptLogView.ReceiptLogViewSet.as_view(), name='ReceiptLog')]
EDIT: code Fix
Added this to 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)

Answer 1

Maybe try something like this:
if serializer.is_valid():
serializer.save()
return Response("success")
else:
return Response(serialzier.errors)

Answer 2

Using a try catch statement
In 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')
serializer_class = serializers.TestCaseCommandRunViewSet
return Response("working")
except Exception as e:
return Response(e)
class TestCaseCommandRunResultsViewSet(viewsets.ModelViewSet):
try:
queryset = models.TestCaseCommandRunResultsViewSet.objects.values('suite_run_id','command_run_id','rule_name','result_id','result','expected_values','actual_values','report_values','extended_values')
serializer_class = serializers.TestCaseCommandRunResultsViewSet
retutn Response("Working")
except Exception as e:
return Response(e)
class ReceiptLogViewSet(CreateAPIView):
try:
serializer_class = serializers.ReceiptLogSerializer.ReceiptLogSerializerClass
return Response("working")
except Exception as e:
return Response(e)
