You can look at how it is done in RForum (look at localization.rb, and 
its uses).

Which error messages are you referring to? 
If you mean the ones created by the validation macros, then there''s a
parameter for your own message, eg:

validates_uniqueness_of :username, { :message => "Användarnamnet är
redan registrerat" }

and if you''re using english column names (ie "username"
which, in for
example swedish, would be "användarnamn") you can either create a
lookup table in your model that "translates" the attribute name for
display purposes, or as in the above example, simply take the easy
road and pass the field/attribute name in the error message. Then you
can output it in you view with something like this:

<% if @post.errors.count > 0 %>
  <h3>The following errors was found</h3>
  <ul>
  <% @post.errors.each do |attr_name, message| %>
    <li><%= message %></li>
  <% end %>
  </ul>
<% end %>

This means of course that you''ll have to pass the attribute name in
every error message, but to my knowledge that is the easiest way.


However, if you where talking about a full-on localization module
there doesn''t seem to be anything done together with rails yet, apart
from the yaml implemention in RForum (as alexey said)

module ActiveRecord
    class Errors
    @@default_error_messages = {
      :inclusion => "is not included in the list",  
      :invalid => "is invalid",
      :confirmation => "doesn''t match confirmation",
      :accepted  => "must be accepted",
      :empty => "can''t be empty",
      :too_long => "is too long (max is %d characters)",
      :too_short => "is too short (min is %d characters)",
      :wrong_length => "is the wrong length (should be %d
characters)",
      :taken => "has already been taken",
      }  
    cattr_accessor :default_error_messages 
 end
end

snowdevil $ ruby script/console development
Loading environment...
irb(main):001:0> ActiveRecord::Errors.default_error_messages[:empty]
=> "can''t be empty"
irb(main):002:0> ActiveRecord::Errors.default_error_messages[:empty]
"dude...."
=> "dude...."

Hope this helps

That''s a very good hint, I hadn''t seen that before, thanks.

Unfortunately, that''s not the end of the story:
module ActionView
  module Helpers
    module ActiveRecordHelper
      def error_messages_for(object_name, options={})
          [SNIP]
          content_tag("div",
            content_tag(
              options[:header_tag] || "h2", 
              "#{pluralize(object.errors.count, "error")}
prohibited this #{object_name.gsub("_", " ")} from being
saved"
            )
         [SNIP]

Of course you can work around that with your own error-displaying
view-helper function as well, but...

The best solution seems to localized the Rails Code for everyone.
we got to work on putting ''human messages'' out of the rails
code...
someone for this ticket or patch ?  :D
