At least I can help with the original problem Your view function should return an HttpResponse object, but inside your view you have this
new_title = title_form.save() return new_title new_title is an instance of your ObjectName model, that's why Django crashes when it tries to use it as an HttpResponse object and throws that error. I'm not quite sure what are you trying to accomplish in your view.
