Rails - Jun 2006 - Loop to insert into database

I have a form that will display a brief description of a topic and 
provide links (1 to many) for that topic.  So I currently have two 
tables Articles and Links.  I also some stuff on the form that will add 
links to the form so that you can create as many was you would like. 
The problem I am having is finding out how to submit each link to the 
databasen and aligning those links to the articles.

What do you recommend?

After reading that even I was confused and I wrote it.

I have a form that is taken these fields:

in_your_classroom:
    title
    description
    publish_date

in_your_classroom_links
    title
    url
    description

Each IYC feature can have 1 to many links.  I have a link that will add 
a new set of form fields for an extra link.  currently I have each form 
field set like this:

<%= text_field "in_your_classroom", "title[]" %>
<%= text_field "in_your_classroom", "url[]" %>
<%= text_area "in_your_classroom", "description[]" %>

I want to loop through each link and add them to my database.  What is 
the general practice when doing this?

Thanks.

Seth
