I am trying to create a form dropdown select field and I would like to
use an array to build it.
My code is:
<select name="order[ship_to_state]"
id="order_ship_to_state">
<% states = ["Alabama", "Alaska",
"Alberta", "Arizona",
"Arkansas" ]
states.each do | state | %>
<option value="<% "#{state}" %>"> <%
"#{state}" %></option>
<% end %>
</select>
But I get an empty dropdown.
What should I change to make this happen?
Thanks,
Elle

Try:
states = [''Alabama'', ''Alaska'',
''Denial''].freeze
collection_select(:order, :ship_to_state, states.map{|s| [s,
s]}, :first, :first)
It''s air-code (untried, untested), but might get you on the right
track.

I mean it''s a string anyway. You could achieve the same with just <%= state %>, making for more readable code -- is there an advantage I am not aware of in using the <%= "#{state}" %> way? -- Edd Morgan http://www.eddm.co.uk +44 (0) 7805 089097 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Perhaps I wasn''t clear:
<% states = [''Alabama'', ''Alaska'',
''Denial''].freeze %>
<%= collection_select(:order, :ship_to_state, states.map{|s| [s,
s]}, :first, :first) %>
This should generate a <select> tag for the instance variable :order
that affects the ship_to_state attribute. It should contain a
<select> tag for each state with a value and display element exactly
the same: The name of the state.
What, specifically, is not working?

I''m so silly to forget to add as in <%= state %> I''m not at my computer at the moment. Will try this a bit later.
