Put the select into a partial then do this:
This is what I came up with a while back to re populate a select box
after a DB add.
Mop is just my main Table / form.
When you add the person to the db then do this:
@mop = Mop.find(params[:id])
a = Contact.all.collect{|p| [ p.id ] }
b = @mop.contacts.all.collect{|p| [ p.id ] }
c = a-b
ar = Array.new
c.each{|arr|
arr.each{|p|
ar << p
}
}
@contacts = Contact.find(:all, :conditions => ["id IN (?)",
ar]).collect {|p| [ p.name, p.id ] }
In the RJS do this:
page[:contact_id].replace :partial => 'updateContactList', :locals =>
{ :contacts => @contacts, :mop => @mop, :person => @person }
Partial similar to this:
<%= select('contact', 'id', @contacts, {:prompt => 'Select Contact'},
{ :onchange => remote_function( :url => { :controller =>
'contacts', :action => "ajaxshowcontact", :id => @mop},
:with => "'contactid=' +
this.value" )
} ) %>
