I would like to know how to show a personalized error with get_object_or_404?, I do not want regular http404 pages, I want to display a message with the result none

Answer 1

get_object_or_404()- Essentially simple 5 line function. If you have no specific reason for using it, simply do:

try:
    instance = YourModel.objects.get(pk=something)
except YourModel.DoesNotExist:
    return render_to_response('a_template_with_your_error_message.html')

If for any reason you have to use get_object_or_404 (), you can try putting it in a block try: ... except Http404: ..., but I honestly can't come up with a plausible reason for this.
