Need Activerecord modeling advice

What do you consider the best approach to having 20 or more forms related to the same model? The thing is that I may have to template forms for an enterprise level solution. Should I make one model with a dozen form input attributes and build each form page separately, or is there another way that I can pull this off efficiently?

Thanks

Uh, "don't" ?

What is the use case that requires "20 or more forms" for a model?

I will build each form with separate models. Which is why I wanted to use the form builder instead. But, that may come back to haunt me at some point. I will just use the traditional method instead.
