Rails 1.1, Markaby, options_from_collection

thing:

Stuck on options_from_collection_for_select
Hi everyone,
I''m stuck on something that seems to be super easy, but maybe I''m just
too tired to see the obvious answer.
I''m trying to make a drop down with select_tag and
options_from_collection_for_select. I''m trying to fill this drop down
list with different human races (white, black, hispanic, etc. in the
database under the name field, with a unique id

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:

Using group in with find in an ActiveRecord appropriately
I''m playing around with the Practical Rails Projects code, and was
attempting to make a change for graphing data differently using
groupings.
Basically the code went from:
total_weight = @exercise.activities.collect {|e| e.repetitions
* e.resistance}
workout_dates = @exercise.activities.collect {|e|
e.workout.date.to_s}
To:

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.

options_from_collection_for_select(@fruit_types, "id", "kind", 3)) %>
the list still displays the first option (No Contract) in the list.

Code that follows, works perfectly -

The following code, does not. The helper function never even seems to
be called.

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?

Rails documentation gives examples of using

How could it be done with one?
