How to handle “matching query does not exist” when getting an object

by

That depends on what you want to do if it doesn’t exist..

Theres get_object_or_404:

Calls get() on a given model manager, but it raises Http404 instead of the model’s DoesNotExist exception.

get_object_or_404(World, ID=personID)

Which is very close to the try except code you currently do.

Otherwise theres get_or_create:

personalProfile, created = World.objects.get_or_create(ID=personID)

Although, If you choose to continue with your current approach, at least make sure the except is localised to the correct error and then do something with that as necessary

try:
   personalProfile = World.objects.get(ID=personID)
except MyModel.DoesNotExist:
    raise Http404("No MyModel matches the given query.")

The above try/except handle is similar to what is found in the docs for get_object_or_404…
