I asked about this before but perhaps didn''t state clearly what it was I wanted. I have a select box and based on the user''s choice a second select would be populated that relates to the choice made in the first box. I''ve googled around and found little on dependent drop downs for rails. Kind of surprises me since I''d think it would be a more common function. Can anyone point me in the direction ?

Alright, I found the thread. It probably makes sense for me at this point to get familiar with Ajax, rjs and all in Rails, before attempting.

As I''m reading through the AJAX stuff (in AWDWR) I''m wondering about a few things If I have this one element in my form where when user picks option from another element is loaded - is this more of a javascript coding , like "onclick" or something that could be done with what''s available within Rails. One idea is I''m having is to have that section of my form as a partial that will get triggered in the controller to update. This make sense ?

Just use an observe of some element that calls a method in your controller, which in its turn will update a div on your page with a partial. Or you could look at the UJS plugin, I found it most useful as your view is a lot cleaner than when using the built-in methods.

I think you will want to read up on observers. In your initial view, create your 1st drop-down and an observer that watches that field. When a value is chosen in the drop-down, the observer will call a method in your controller (which in turn calls a partial view) and renders the 2nd drop down. -----Original Message----- From: rubyonrails-talk-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org [mailto:rubyonrails-talk-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org]On Behalf Of Dark Ambient Sent: Thursday, September 07, 2006 8:17 AM To: rubyonrails-talk-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org Subject: [Rails] Re: dependent drop downs As I''m reading through the AJAX stuff (in AWDWR) I''m wondering about a few things If I have this one element in my form where when user picks option from another element is loaded - is this more of a javascript coding , like "onclick" or something that could be done with what''s available within Rails.

Question about ''frequency'', does that not require any time of click or submit, but works on the machine clock to check the field?

Really sorry here because I''m getting an error just setting this up.
So maybe this shouldn''t even go in this thread but I''ve
already taken
too much bandwidth probably.
Right now I''m getting a no method error on a nil object.
I have two tables, pays and wages. (pays is the one they would choose
to decide on what is presented in the wages select)
I have both models set up.
class Pay < ActiveRecord::Base
has_many :wages
end
class Wage < ActiveRecord::Base
belongs_to :pay
end
Here is my first select -
<select name="pay[wage_id]">
<option value=0>Select Type</option>
<% @wage.each do |wage| %>
<option value="<%= wage.id %>"
<%= '' selected'' if wage.id == @pay.wage_id
%>>
<%= wage.wage %>
</option>
<% end %>
</select></p>
Anyone see anything wrong.
The pays table is id and name
The wages table is id hran and name
the hran column is really the id that should match the id in pays.

Make sure you''re filling @wages in the controller. Also, look into
"collection_select", similar to the following, to replace your code in
the view
<%= collection_select :pay, :wage_id, @wages, :id, :wage %>

Still a bit confused over what tables , whether it is one table, or
multiple and joined.
When you say infotantra[category_id] is this a join ? Meaning is
infotantra one table and category_id from another table ? Or
category_id is just a column/method from class infotantra ?
The way my table is set up is like this:
first table:
id name
1 hourly
2 annual
So here I''ve written out the select:
<%= @pays = Pay.find(:all, :order => "id").map { |p| [p.name,
p.id] }
select(:pay, :name, @pays)%>
Then as an example (i''m not going to dump the entire table here, but
this is the second table:
id hran name
1 1 5.00
2 1 10.00
3 2 20,000
4 2 50,000
<div id="dollar">
<%= @wages = Wage.find(:all, :order => "id").map { |w| [w.name,
w.id] }
select(:wage, :name, @wages, {}, {:disabled => true}) %></div>
Now the observer_field :
<%= observe_field([:pay.id],
:frequency => 0.10,
:update => "dollar",
:url => {:action => :update_dollar},
:with => "''pay.id=''+value") %>
(I left the frequency in for now as there is no form_tag on the page
nor a submit button)
dollar is the DOM element. So far though I haven''t written the
controller code and not sure how to. I''m still a newb (if you
haven''t
noticed) but I would be inclined to just do something like
if pay.id == 1
...code to make observer update field
else pay.id == 2
Sorry, if none of this makes sense.

It took me some time to make sense of all the various streams of help
here.. Figured I''d post a very standard example of how this works for
anyone who needs it.:
##############################
#[test_controller.rb]
class TestController < ApplicationController
def main
end
def update_sub_category
puts @params["item1"]
items = {"1" => ["apple", "asphalt",
"averatec"], "2" =>
["bat", "base", "bowling"], "3" =>
["cat", "carol"]}
@html = "<select name=''item2''>"
@html += "<option
value=''0''>Sub-Category</option>"
items[@params["item1"]].each do |sub_category|
@html += "<option
value=''#{sub_category}''>#{sub_category}</option>"
end
@html += "</select>"
render_text(@html, :layout => false)
end
end
###############################
# views/test/main.rhtml
<%= javascript_include_tag "prototype" %>
<div id="item1_div">
<select name="item1">
<option value=0>Select Category</option>
<option value="1">a</option>
<option value="2">b</option>
<option value="3">c</option>
</select>
</div>
<div id="item2_div">
</div>
<%= observe_field(
"item1",
:frequency => 0.25,
:update => "item2_div",
:url => { :controller => "test", :action =>
:update_sub_category },
:with => "''item1='' + value") %>
##########################################
sure there''s room for improvement but it gets a functional example
