Starting over, mail program sent prematurely...
2 models, Salons, Reviews
In ApplicationHelper.rb...
SALON_STATES = Salon.find(:all, :group => ''state'',
:select => ''state'')
So in any view, I can collect...
<%= options = [[ ''Select a State'', @state ]] +
ApplicationHelper::SALON_STATES.collect { |salon| [salon.state] }
select ''salon'', ''state'', options %>
This is OK (perhaps maybe not the best way to handle and I''m open to
suggestions)
But now, I want a list of cities in just the selected state and I can''t
manage to accomplish this anywhere but in controller code which is not
very dry since I would have to replicate this code in several different
controllers (like Reviews).
@cities = Salon.find(:all, :conditions => [''active = true AND state
= ?'', @state], :group => ''city'', :select =>
''city'')
Suggestions?

Hi Craig, I had to do something similar to this in one of my apps. Ryan Bates did an excellent tutorial you may want to consider. http://railscasts.com/episodes/88-dynamic-select-menus Have fun, Franz -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

It works (for suitably small values of "works") in development mode, but will cause odd behavior when deployed to production. At a minimum, Salons which are added after the application starts won''t show up until the server restarts. In a dynamic environment like Passenger, you could even end up with different processes having *different* lists in SALON_STATES... --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
