I''m sorry to be asking trivial questions, but I''m new to RoR
and am
hooked :), so I''m very impatient to get things up and running.
given two related tables, "pcs" and "venues" (venues have
many PC''s and
each PC belongs to one venue only) I can use a select() to present venue
names in the "new PC" form along with other PC details to be
registered.
I''ve done this by adding <%= select('''',
'''', venue.find_all.collect {|venue|
venue.name}) %>
to my _form.rhtml for registering new PC''s.
Now when you register a new PC, you can choose the venue that it
belongs to by name, but I need to then send the venue_id (the foreign
key in pcs) and not the venue name from the form. Can someone advise
me on how I might do this?
Also, I know that I''m really supposed to write something in the
appropriate controller or write a helper method to populate a variable
which I can then use in my _form.rhtml, but I''m not sure how to do
that and would appreciate pointers there too.

You will most likelt want something like this...
<%= select("pc", "venue_id", Venue.find_all.collect {|v|
[v.name, v.id]} )
%>
this will create a select with the name as the displayed value, and put the
id as the actual value submitted with the form. also by adding pc and
venue_id as the first 2 parameters, the select will automatically select the
Venue described by @pc.venue_id. Then you can reuse this for for editing a
PC as well.

Brilliant Mark! It worked like a charm. Now I''ve got to do my homework and find out how to abstract as much as possible into a controller or a helper. Thanks.
