I''m working on a subscription form that has to be tied to paypal using the paypal ipn plugin at http://elctech.com/products_ruby_paypal.shtml. I''ve got my subscription (signup) form setup to include the creditcard information as well as the billing address etc. It''s a modified version of the signup form from the acts_as_auth plugin. I want the model to not save if the paypal direct payment does not return ''success". Do I create a before_save filter for that or what is the best method to use? -- Posted via http://www.ruby-forum.com/.
