Hi Ali, If you follow the pattern laid out in Django's documentation, you'll avoid the problem:
https://docs.djangoproject.com/en/dev/topics/forms/#using-a-form-in-a-view The key part is that on success, the form processing issues a HTTPResponseRedirect. This prevents the back button from repopulating the form - even if it redirects to the same URL that you used to submit the form in the first place.
