I have been able to make the IPN works for some use case however, when i pay without paypal account (mastercard,visa...) my app receive the params but the create! method fails silently. The logs contain the params sent by paypal, and there is no significative difference between an IPN from a paypal account and a non-paypal payment.
I have rails 3.0.3 and it seems impossible to make content.blank? work with both create a destroy. And i should add my nested element use paperclip.

How can i know what fails in the create! method?
