User defined form in Rails

I am creating a rails app wherein I have a problems model. How do i create a form that asks the user to choose the range of values that he wants to see. i.e the form asks him to choose say the cause of the problem and between what dates such problems could have occurred and then output those results from database?

Thank开发者_运维知识库s in advance.

I found Dynamic Forms a little while back but haven't had a chance to try it yet. It looks like it might be what you're chasing.
