Question on insert to multiple tables?

Hello, every day i love more rails xD because after struggling a bit I could finally install the Active Scaffold plugin and it works great with this.

But now it is time to grow a little more on rails and am trying to make an ordering system and products. Which on my system I have these 3 tables:

Product:          => id_product          => name          => amount          => prices

Request:          => id_order          => date_order          => recipient          => address

Detalles_pedido:          => product_id          => order_id          => price_unity          => amount          => total

So you see, the Active Scaffold allows me to work on each table CRUD apart, but now I need to create a form based on which prodcuts can submit all of my store and that the user choose the amount of each and then add address of the recipient and the date of order, fields that are in the order table. But while I have to insert in "ORDER_DETAIL 'respective ids and the amount and the respective total for the order.

And since I have been finding out something about a method @ task = @ (params [: task]) but does not help much, because maybe you need now is an array to insert in "ORDER_DETAIL" and that it could be done in php but not much beyond that domain and, lo conosco no rails at all.

If rails is not an easier way to do this or if I can do all this with the Active Scaffold, as I see all these respects the relationship and insertions in different tables at once.

The truth'm a bit lost and I hope they can give me a hand that cat xD no idea where to start now!

You are probably better of posting on the activescaffold group:

Unfortunately their documentation site is down at the moment but I'm pretty sure they describe how to do model associations in activescaffold.

To be honest if you are a beginner I wouldn't recommend starting out on activescaffold - get the Agile Web Development with Rails book and learn the fundamentals first:
