Django DoesNotExist
First way:
try:
# Your code goes here
except Model.DoesNotExist:
# Handle error here
Another way to handle not found in Django. It raises Http404 instead of the model’s DoesNotExist exception.
https://docs.djangoproject.com/en/3.1/topics/http/shortcuts/#get-object-or-404
from django.shortcuts import get_object_or_404
def get_data(request):
obj = get_object_or_404(Model, pk=1)
I have found the solution to this issue using ObjectDoesNotExist on this way
from django.core.exceptions import ObjectDoesNotExist
......
try:
# try something
except ObjectDoesNotExist:
# do something
After this, my code works as I need
Thanks any way, your post help me to solve my issue
The solution that i believe is best and optimized is:
try: #your code except "ModelName".DoesNotExist: #your code
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
