Newbie - populating select list from db - BUMP :)


#1

Hi!

in the same problem with a select with some values from db:

the following select in test.rhtml:

<%= select(:listSetting, :code, @listSettings) %>

where

@listSettings = ListSetting.find(:all, :order => “code”).map {|u|
[u.code, u.id] }

i have an observer_field defined in test.rhml as below:

<%= observe_field(“listSetting_code”,
:update => “values_span”,
:url => {:action => :listSetting_code}
)
%>
which will observe the select object and run the code from
ListSetting_code method from controller.

the log after changing the select is as below:

Processing ListAdminController#listSetting_code (for 127.0.0.1 at
2006-03-22 14:39:17) [POST]
Parameters: {“action”=>“listSetting_code”, “value”=>“listSetting_code”,
“1”=>"", “controller”=>“list_admin”}

2 short n00b questions:

  1. what it means “1”=>"" in the log file?
  2. how do I get the value of option selected in controller method?

TIA.
