It is a good practice to add or edit an object in the same view?

[Neto]

Hi, It is a good practice to add or edit an object in the same view or is it better to separate?

For example:

def add_edit(request, id=None):
    form = MyForm(request.POST or None)
    if request.method == 'POST':
        if form.is_valid():
            form.save()
            return HttpResponse('success')
    render(request, 'add_edit.html', locals())
