Maybe i did not describe it clear.Please look at attachment.I think  
using model instead of non-model tags is better way,but don’t know how  
to define the model,migration,validation…?

I think you need to explain your requirement a bit better. Have you  
written a spec of what you are trying to achieve? If not you could do  
so, this may even help to clarify your ideas such that you answer the  
question yourself.

I have done a project similar to yours in PHP long ago. As far as I  
know, you can provide only very basic validation if you let users  
build their own form. I used a table for each type of field. That is  
all string elements in a form will get stored in a particular table,  
all boolean elements will get stored in another table and blah blah.

You can do this stuff using Rails, but its not going be easy as you  
think. But it will be far easier than you do it with PHP.
