Drop-down menu in form with options from database with conditions? Rails 2.3.15 -

i'm writing piece of app allows upload photos , assign them bus. want drop-down menu name values. buses can either enabled or not. i'd restrict list enabled buses. i'm not sure how in form drop down menu.

this know how do:

    <% bus.find(:all, :conditions => {:is_enabled => 1).each |bus| %>       <%= bus.name %>     <% end %> 

but don't know how put code in form without breaking in variety of different ways, , don't know other way these names. app uses older version (rails 2.3.15).

this best guess on how it:

<% form_for @bus_image, :html => { :multipart => true } |f| -%>   <%= f.error_messages %>      <div class="field">        <%= f.label :name %><br />        <% bus.find(:all, :conditions => {:is_enabled => 1}).each |bus| %>        <%= select(bus.name) %>        <% end %>      <div>  <% end -%> 

... gives me wrong number of arguments (1 3).

thanks, let me know if need/want more information.

use :

f.select(:bus_id, bus.find(:all, :conditions => {:is_enabled => 1}).map{|b| [ b.name, b.id ] }, {:include_blank => true }) 

in place of :

   <% bus.find(:all, :conditions => {:is_enabled => 1}).each |bus| %>    <%= select(bus.name) %>    <% end %> 

hope help.
