Ruby on Rails makes it easy to take user-submitted parameters, and pass them along to the database via Active Record. That’s great, but raises questions about security. In this talk,  Tara Scherner De La Fuente teaches us about  “strong parameters,” the mechanism in Rails that ensures we only pass to our models those values that we really want and need to pass along. She gives us hints for using them, and for ensuring that our applications are as protected as they can and should be.
