Django DoesNotExist

python django django-models django-views

This line

 except Vehicle.vehicledevice.device.DoesNotExist

means look for device instance for DoesNotExist exception, but there's none, because it's on class level, you want something like

 except Device.DoesNotExist

python django django-models django-views

I have found the solution to this issue using ObjectDoesNotExist on this way

from django.core.exceptions import ObjectDoesNotExist......try:  # try somethingexcept ObjectDoesNotExist:  # do something

After this, my code works as I need

Thanks any way, your post help me to solve my issue

python django django-models django-views

The solution that i believe is best and optimized is:

try:   #your codeexcept "ModelName".DoesNotExist:   #your code
