this is wrong:
<select id="state" name="state">*
*name (and id) should be in AS style, which is very similar (if not same) to
RoR standard format of naming object attributes in a form. Take a look at
finder.rb in AS. It explains in more detail. (PS: i think that should be in
the wiki)
so, you may use name="record_state_id"
*
*besides, you could do everything from
# /views/customers/_state_form_column.html.erb
much less code and simpler in a helper, with something like this:
def state_form_column(record, input_name)
if not @state.nil?
select record[:state], @states, :prefix => input_name
else
text_field record, :state, { :size=> 30, class=>"state-input
text-input", :prefix => input_name}
end
end
the "selected" property is set automagically by RoR's select helper:
http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#M001592
now, for the update_states, don't know how to render from a helper, but, how
about taking a look at form_column_chaining?
hope that helps,
