Hi,

Is there an existing helper or plugin that let’s one define a dynamic  
input form page based on a model?

For example I am going to have a tableless model to collect the input  
parameters required for a report to be run. Given I have the model  
(albeit based on a “ActiveRecord::Base Without Table”), is there a  
helper or plugin that would let me say “render an input form for this  
model, using validations defined in model”?

thanks
