Select Box Question
Hi,
Yet another newbie here... I''m writing an appliction in Rails, and I''ve
Ajaxified my select boxes so they update dynamically. I used the
"observe_field" method to monitor changes to my select box. I find that
it''s kind of erratic... it updates constantly and makes the selection

select vs. select_tag
I have a "Users" object and
a "Timesheets" object. Each timesheet entry belongs to a User, which is
selected from a drop-down list. The timesheet has a user_id field. (The
user needs to have an option to select a different user due to the way
our system works.)
If i use the "select" object, which is bound to the Timesheet model,
using this code:

selected value for options_from_collection_for_select
Hey,
I am trying to get a select list with a selected value in it. Even if I
put in an integer, like this,
<%= select_tag(fruit.id, "<option>No Contract</option>" +
options_from_collection_for_select(@fruit_types, "id", "kind", 3)) %>
the list still displays the first option (No Contract) in the list.

options_from_collection_for_select
I have just started using RoR and am creating some select boxes on my form
with the following code:
<%= select_tag(options_from_collection_for_select(Owner.all, :id, :fname))
%>
My problem is that it does NOT return the first record from the table, but
just the second and succeeding records.
Does anyone have any ideas on how I can get the first record included in
the select box?
Thanks.

Parameters for FormOptionsHelper select vs. FormTagHelper select_tag
I must be missing something when it comes to the parameter differences
between form FormOptionsHelper select and FormTagHelper select_tag.
Code that follows, works perfectly -
<%= f.select :unit, units_to_select(@product), :size=>"20"%>
The following code, does not. The helper function never even seems to
be called.

option_groups_from_collection_for_select with a ActiveRecord::Base single object
Rails documentation gives examples of using

How could it be done with one?

It has the following:

collection_select default selected value
Hiall,
Unfortunately I just can''t find out how to setup a default selected
value when using collection_select. My call is like so:
<%= collection_select(:consultant, :lastname, @consultants, :id,
:lastname, { :selected => @current_consultant.id } ) %>
which is not working, I debugged so far that I know that
@current_consultant.id contains the correct value.
Any tips?

Linking two HTML SELECT''s together
Hi,
How do I link two HTML SELECT''s together. Let''s say for example that I
have a drop-down list with a list of all countries. Once the user
selects one of the countries I would like to make an AJAX call back to
the server to populate the second drop-down list with all of the cities
for that country.
Any ideas on how to go about to do this?
