rails3 i18n accepts_nested_attributes_for how-to translate? - ruby-on-rails-3

Question

I'm using Rails 3.2.6 and this is an example case:
class Man < ActiveRecord::Base
has_many :eyes
accepts_nested_attributes_for :eyes
end
class Eye < ActiveRecord::Base
belongs_to :man
validates_inclusion_of :color, in: { %w[brown green blue] }
end
Views (in HAML):
= form_for #man do |f|
- if #man.errors.any?
#error_explanation
%h2= t 'errors.messages.record_invalid', count: #man.errors.count
%ul
- #man.errors.full_messages.each do |msg|
%li= msg
= f.fields_for(:eyes) do |b|
.field
= b.label :color
= b.text_field :color
.actions
= f.submit :submit
it.yml:
it:
activerecord:
attributes:
customer:
eyes: Occhi
customer/eyes:
color: Colore
errors:
models:
man/eyes:
attributes:
color:
inclusion: non valido
However the label of color is not translated (but it is with 'actviterecord.attributes.eye.color'), the attribute in the error message is only "Occhi" and the rest is errors.model.eyes.attributes.color.inclusion instead of errors.models.man/eyes.attributes.color.inclusion
The error message is the errors.model.man.attributes.eyes.inclusion, but how can I differentiate it? It should be something like "Occhi Colore non valido" instead of "Occhi non valido"

Answer 1

Try this out:
it:
activerecord:
attributes:
# set the name used in nested attribute error messages
customer/eyes:
color: Occhi Colore
errors:
models:
# change the error message for eye color not included in the list
eye:
attributes:
color:
inclusion: non valido
messages:
# change the inclusion message globally
inclusion: non valido
helpers:
label:
# set the label used by form builder for labels
man[eyes_attributes]:
color: Occhi Colore
