Question

Create a flexible, localized, Ruby-on-Rails list-of-values

Answer 1

+1 A:

You can put the definition of an array in /config/locales/some_language.yml

for example you could have the following in en.yml

en:
   experience_levels: 
          1: Beginner 
          2: Intermediate
          3: Advanced 
          4: Fluent
          4: Native

To get the key value pairs into a helper, the following should work:

def experience_levels 
    I18n.t(:experience_levels).map { |key, value| [ value, key ] } 
end

To use this in a select box,you would just put the following in your form_for

<%= f.select :experience_levels, experience_levels %>

If you are using form_tag instead you need the following:

<%= select_tag :experience_levels, options_for_select(experience_levels) %>

Thank you, thank you, thank you. Any thoughts on how I would add a localized 'Choose...' option to the top of the list? Perhaps 0: Choose...?

You could add the "Choose" element to the array. But maybe it would be better to have a seperate value that is prepended in the helper before it's inserted into the select tag. This way you can use it for all select tags and only have one place where you change it.
