human_attribute_name scopes translations differently for nested classes since rails 3.0.2

Calling

Mss::Units::Absence::Search.human_attribute_name(:x)

seeks for translation key:

activemodel.attributes.mss/units/absence/search.x

on Rails 3.0.1

but for

activemodel.attributes.mss.units.absence.search.x

on Rails 3.0.2 and 3.0.3

This is due to changes in :
GEM_HOME/gems/activemodel-3.0.2/lib/active_model/translation.rb

The changelog states that:

*Rails 3.0.2 (November 15, 2010)*

* No changes

so i believe that it was not intentional.

I was just searching for this bug too and you gave me the answer.
I'm running Rails 3.0.3.

Problem is.. what happens now if i corrent my locales to this new design, then it will be considered a bug and "fixed"?

to fix this bug try redesign locale files to
structure for namespaced models

Example

class Hotels::Period
config/locales/pl/models/hotels/period.yml

pl:
  activerecord:
    models:
      hotels:
        period: 'okres'
    attributes:
      hotels:
        period:
          name:                  'nazwa'
          start_date:            'początek'
          end_date:              'koniec'
          days:                  'dni'
          discount:              'zniżka'

My temporary workaround is :

ActiveModel::Name.class_eval do
 def i18n_key
  @fixed_i18n_key ||= ActiveSupport::Inflector.underscore(self).to_sym
 end
end

nice work ;)
i`ve another interesting problem with i18n on forms helpers

  = form_for(@period, :url => period_path(@period), :html => { :multipart => true, :method => :put }) do |f|
    = f.label :name, :class => 'form-label size-60 fl-space2'

autotranslate :name doesn't work with namespaced models :(

@robert, as i understand, the fix is correct, only the CHANGELOG is not. Right? dot notation should be the correct way.

@robert

i had tried to do labels with I18n from http://blog.plataformatec.com.br/2010/02/rails-3-i18n-changes/
but this way doesn`t work

i found answer.
'action_view/helpers/form_helper.rb' lines 890

            p "#{object_name}.#{method_name}" # me puts here
            I18n.t("helpers.label.#{object_name}.#{method_name}", :default => "").presence


return "hotels_period.name"

so in locales yml, keys must be like :

pl:
helpers:
label:
hotels_period:
name: 'nazwa'

not

  hotels:
    period:
      name:                  'nazwa'

its just another inconsistence ?
