Mass edit in Ruby on Rails

Let's say you have some products which have 2 fields, a description and a stock value.

How do you layout a form of all the products in an action named mass_edit with fields so a user can edit some, press submit and then save them in a mas开发者_如何学编程s_update?

I have used nested forms in a order-order_line scenario but i can't seem to figure this one out.
