How can I handle errors in Django views?

In Django, you can handle errors in views using try-except blocks. This allows you to catch exceptions and respond accordingly.

Can you give me an example of using try-except in a Django view?

Sure! Here's a simple example:

from django.http import HttpResponse

def my_view(request):
    try:
        # Your code here
        result = 1 / 0  # This will raise a ZeroDivisionError
        return HttpResponse('Result: {}'.format(result))
    except ZeroDivisionError:
        return HttpResponse('Error: Division by zero!')

This catches the ZeroDivisionError and returns a user-friendly message.

What about handling 404 errors?

For 404 errors, you can use Django's built-in Http404 exception. You can raise it in your view like this:

from django.http import Http404

def my_view(request, item_id):
    try:
        item = get_object_or_404(Item, id=item_id)
        return HttpResponse('Item: {}'.format(item.name))
    except Http404:
        return HttpResponse('Error: Item not found!')
