I am using Spree for my E-Commerce.
I have to integrate Paypal Payment Gateway. The tutorial that I followed was [Paypal Integration with spree][1] [1]: https://github.com/spree-contrib/better_spree_paypal_express. I had successfully created sandbox account. When I go for transaction all flows work fine but after I am redirected back to my own site, it throws an error "NoMethodError in Spree::PaypalController#confirm", I don't see this controller in my code and that tutorial link didn't do anything to create this one.
Please help me to resolve this. Thanks.
I am sorry. This is not a general issue.
Error was because of my code. Paypal did work fine and redirected fine.
I just had to fix my logic to handle this redirection of paypal using spree.
