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.

Yours,

Hi Russ,

thank you so much for reply.

But I tested ago the form with  HTTPResponseRedirect and this don't work for me.

I decide to save csrf token in my models and check it in view and this solution work for me.

Best Regards,

Hallaji
