QUESTION
I am trying to include some exception handling to handle queries that return None
, If none is returned I just want to display a simple JsonResponse
message. Working with FBVs, I've done this pretty simply. But when using class based views, my except
block is not doing as I expect.
ANSWER
Answered 2021-Jan-04 at 19:40From my understanding, the DoesNotExist exception would catch the query returning
None
?
No, .first()
does not raise an error in case it can not find a record, in that case it simply returns None
. This will thus not raise any DoesNotExist
exception. There is nothing "special" about a DoesNotExist
exception, this is just an exception like any other exception.
You use .get(…)
[Django-doc] instead of .first()
to get a DoesNotExist

QUESTION
When I started to use Django, I was using FBVs ( Function Based Views ) for pretty much everything including signing up for new users.
But as I delved deep more into projects, I realized that Class-Based Views are usually better for large projects as they are more clean and maintainable but this is not to say that FBVs aren't.
Anyway, I migrated most of my whole project's views to Class-Based Views except for one that was a little confusing, the SignUpView.
...ANSWER
Answered 2020-Jul-16 at 13:04In order to make SignUpView in Django, you need to utilize CreateView
and SuccessMessageMixin
for creating new users as well as displaying a success message that confirms the account was created successfully.
Here's the code :
