What I read from the documentation: select
(ActionView::Helpers::FormOptionsHelper)
"The option currently held by the object will be selected, provided that
the object is available."
Maybe you must use, while you have populated the object @channel in the
controller rendering that view.
<%= f.select("channel", "id" , Channel.find(:all, :order => 'channel
ASC', :conditions => ['deleted=0']).collect {|p| [ p.channel,
p.id ]}, {:include_blank => true}, { :onchange =>
"document.channelsform.submit();"}) %>
I am not sure but you may give it a ride.
