Rails - Apr 2007 - Spent over 24 hours trying to figure this - multiple params

I feel really stupid spending over 24 hours trying to figure out 1 line
of code but I still can''t get it.

I have a table addpackages, that I want to update multiple fields from
table rosters based on the selection of a drop down.


In addpackage.rb:
def create
    @addpackage = Addpackage.new(@params["add"])


In new.rhtml (view):
<select name="add[email]">
<%=options_from_collection_for_select(@rosters, "email",
"lname",
selected_value = nil)%>



This code works perfect for obtaining the correct email address based on
drop down and updating the addpackages table.   I could replace
"email"
with "fname", "lname", etc etc and it would work fine also. 
Whats
killing me is I can only get one parameter to pass and update.   I
cannot for the life of me figure out how to pass email, fname, and lname
based on the selected drop down.


Help!!!!!!!!!!!!!!!!!!!

You would need to use param_name[] if you want to be able to read an 
array of parameters instead of just the one value.

For example,

<% choices = options_from_collection_for_select(@rosters, :id, :email, 
nil) -%>
<%= select_tag("email_ids[]", choices, {:multiple => true, :size
=> 10})
-%>

Don''t.  Pass the primary key (ie. ''id'') in the
<select> and then your
controller look up that roster entry and now you have access to everything 
you want.

Okay I made the folling changes to view:
<select name="add[id]">
<%=options_from_collection_for_select(@rosters, "id",
"lname",
selected_value = nil)%>



Now in my controller can you give an example of how to set:
roster.fname = addpackage.fname (I know my syntax is incorrect)


Thanks very much for your help, much appreciated.  This is my first time 
with RoR.

Dn''t you mean the other way?  I think you do... so...

p = Package.new
r = Roster.find_by_id(params[:add][:id])
p.fname = r.fname

....
