I want a way to tell if the form submitted contains errors or not. There're django snippets that use the field form.errors to test for errors (like this one: http://www.djangosnippets.org/snippets/1094/ ) And when I looked at my own form.errors, it indeed contains the error messages. However,

Off the top of my head, you have three choices. 1. Create a hidden field to carry the id (yes, you do know it once you've done that query - it's z.id or z.pk). 2. (My favorite) encode the id as part of the url or as a query parameter in the action attribute of your form. Then access it in the
