Rails - Jan 2012 - Newbie question: How to save multiple records in a single form

Started learning Ruby and RoR a couple of days ago and I''m working on a
dummy app.

I want to allow a user to save 5 records at the same time using a single 
form. Let''s assume "contact" records, with each one
consisting of a single
"name" field. It''s a "user has_many contacts"
relationship.

Anyone aware of tutorials/documentation on how to achieve this? I''m
having
a hard time modifying the code from a single record into multiple ones. 
Chiefly...

1- How to display 5 text fields in the form/correct form tag to use.
2- How to pass an array of those 5 objects to the "create" method (if
it''s
an array that I should pass)
3- How to create the instance variable that has the 5 objects in the
"new"
method so it''s available to the form
