need a help about formtastic

I am using formtastic for form generation In my app i have two model say Account and Profile but there is no association between them because in my profile model i have two cols 'property' and 'value' i have generated form for Account model which has cols like 'username' and 'password' but i want to add fields in form like 'first_name', 'last_name', 'email' but i don't want to store them in account model i want to store them in profile model like

property       value
first_name     Ryan
last_name      Bates
email          ryan@bates.com 

because of this i don't create any association between these two table.

how can i开发者_高级运维 implement this? can i use semantic_fields_for profile model if there is no association?

Please help

This isn't really an answer, but why on earth are you modelling this way? Formtastic is built on top of and for The Rails Way (and common relational database conventions). I would suggest that if you're going to go this far away from standard Rails modelling for this, Formtastic will only make life harder, not easier.
