form_input

https://github.com/raxoft/form_input

This gem allows you to describe your forms using a simple DSL and then takes care of sanitizing, transforming, and validating the input for you, providing you with the ready-to-use input in a model-like structure. Both simple forms as well as multi-step forms are supported. Includes handy accessors for automatically building the forms and reporting error messages using a templating engine of your choice. Localization support with builtin inflection rules can be enabled, too.
