Obtaining a selected value from observe

Rails
1

This works except for one thing…if there’s a value in
placement.client_slot_id, it doesn’t ‘select’ the value in the selection
list. How can I get it to select the value that matches
@placement.client_slot_id.name ?

view

<%= select_tag ‘placement’, ‘client_slot_id’,
:selected => @placement.client_slot.name %>

  <%= observe_field(
    :placement_facility_id,
    :frequency => 0.5,
    :update =>  :client_slot_id,
    :url =>  { :controller => 'placements',
    :action => :lookup_client_slot },
    :with =>  "'facility_id='+escape(value)") %>

controller
def lookup_client_slot
@client_slots = ClientSlot.find(:all,
:conditions => [“facility_id = ?”, params[:facility_id]]
).collect {|fac| [fac.name, fac.id]}
render :inline => “<%= select ‘placement’,
‘client_slot_id’, @client_slots %>”
end

According to the docs, select_tag takes the object and a string
containing the actual text blah.

You may want to look at collection_select instead.

I promise that I wouldn’t have posted my question if I hadn’t gone over
and over these api pages and still clanking my head against the wall. I
have used options and collections in quite a few different areas of this
web application but never in this manner.

The issue that I am having is that I am able to return the proper
selection list via controller code rendered inline but no matter what I
try, I can’t get it to match up the current value as the ‘selected’ item
in the selection list itself.

I do notice though, that by having my view code like this…

<%= select_tag(‘placement’, ‘client_slot_id’,
options = {:selected => @placement.client_slot_id}) %>

that it results in queer html…

client_slot_id

because both the select id and name are placement whereas view code…
<%= options = [[“Accepted?”, “” ]] + ApplicationHelper::YES_NO
select(“placement”, “accepted”, options) %>

results in…

Accepted? Yes No
