[Django]-Django DoesNotExist

198

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

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

The solution that i believe is best and optimized is:

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

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.

from django.shortcuts import get_object_or_404

def get_data(request):
    obj = get_object_or_404(Model, pk=1)
