form.collection_select utilizing CONSTANT string array?

Hello RoR World-

i've defined a number of string arrays in /lib/valid.rb which i'm using to validate input for various fields, e.g.

module VALID     TITLES = [ 'Mr.', 'Mrs.', 'Ms.', 'Dr.', 'Sir', 'RoRN00b', 'PhD.', 'DHH' ] end

In my models I've done the following, which is working great for my validations: (from .../models/client.rb)     include VALID     validates_inclusion_of :title,       :in => TITLES,       :message => '%s is Invalid - please enter a valid Title.'

Now I'd like to simplify my user's lives by utilizing these same constants as the basis of my collection_selects in my assorted partials, e.g. (from .../views/clients/_form.erb) <%= form.collection_select( :title, TITLES.all, TITLES, TITLES )%>

My two questions: 1. I'm receiving the error: uninitialized constant ActionView::Base::CompiledTemplates::TITLES despite having my obligatory 'include VALID' statement in my client.rb model; tried adding to controller, no joy. _help_.

2. I'm sure my collection_select syntax above is broken; if/when i get past the unintialized constant error i'm sure I can sort it relatively quickly (i hope), but if anyone's done this before and cares to share their code-fu I'd appreciate it.

Thanks much- --Jeff Coon

Believe that <%= form.select( :title, options_for_select(TITLE), { :prompt => true } ) should work, if I can get the TITLES constant to be recognized...

Thoughts?

Thanks- --Jeff

The containing module for the ERB code isn't the model or the controller, it's part of ActionView::Base.

Try explicitly qualifying the constant as Client::TITLES.

Also, module names are not traditionally spelled in all-caps, but that's just a style thing.

Hi Matt-

Thanks much -- qualifying fixed it.

        <%= f.select( :title, Contact::TITLES, { :prompt => true } ) %><br />

Really appreciate the quick tip- --Jeff
