Re: create a collection select from a array of numbers 1-50
what if i want to add a default value of null at the top if that field is not applicable (with a label of N/A)? something like: <%= f.select(:level, 1..200 + "N/A") %> -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: create a collection select from a array of numbers 1-50
I think that''d be something like:
<%= f.select(:level, 1..200, {:prompt=> "N/A"}) %>
(Not sure if those curly braces are necessary, but they shouldn''t
hurt...)

Re: create a collection select from a array of numbers 1-50
Hmmm--that''s different I think. With :prompt, the string you give isn''t actually stored in the db--it''ll get translated to a null. You can use the very same call in your edit view, and again nulls should be translated into the prompt value. But if you really want to store "N/A" in the db, you''ll have to do something like: # In your model, say: class MyModel < ActiveRecord::Base ALLOWABLE_LEVELS = (1..200).to_a << "N/A" end # and then: <%= f.select(:level, MyModel::ALLOWABLE_LEVELS) %> Mind you, your level field will have to accept strings if you do this...
