Rails - Jun 2006 - Ok, I''m stumped on arrays of form fields

My Alert object has_many Links.  I''ve got the whole system setup where,
once I have the Alert object created, I can use a nice form_remote to 
show the user all the Links currently attached, and add more.  But the 
form itself starts out with 0 links.

What I''d like to do now is construct the form with a couple of default 
"Place link here" objects in the array, and show them as text fields
so
that the user can overrwrite them with their own data.  I successfully 
did this with just one empty link by having:
  <%= text_field ''link'', ''body'' %>

and then looking for param[:link], but I''m stumped on the whole array 
syntax thing, especially when I need to prepopulate it.  Do I need to 
create a separate array, move the values into it, and then let the form 
edit that?  Do I need a variable number of link_x fields and then turn 
them back and forth into an array using a loop?  I''m sitting here
trying
every variation of link[0], link_0, alert_link[0]... and so on that I 
can think of.  But it''s just not sinking in yet.

Thanks for all the help!

Hi Duane, I was trying to figure out the same thing a few weeks ago.
