Django - form wizard step by step

I'm wondering if someone uses django wizard step by step but with back option? I have form with 5 steps and now 开发者_如何学编程it is 'one way form' but I would like to develop it by back option (of course data between steps should be remember). Any idea?

Maybe this will help - http://djangosnippets.org/snippets/1454/

Actually, the FormWizard supports this by default when using session or cookie storage.
