ActiveRecord error messages: translation for fields

Question

I've used the instructions specifies in http://guides.rubyonrails.org/i18n.html to translate fields of my model, but the labels doesn't come translated. What I'm doing wrong.

I have a User model with the field name and I'd like to have it translated to Brazilian Portugues (pt_br), so I got my pt_br.yml:

pt_br:
    errors: "Erro!"
    activerecord:
        models:
            user: "Usuário"
        attributes:
            name: "Nome"
            address: "Endereço"
        errors:
            template:
                body: "Por favor, corrija os campos assinalados"
                header: "Dados inválidos"
            messages:
                blank: "é obrigatório"
                taken: "já existe"
                too_short: "incompleto"

when I got to the page with a form:

<% form_for(@usuario) do |f| %>
<%= f.error_messages %>
<%= f.label :name %>
<%= f.text_field :name %>
<% end %>

I sill have the field labeled as "name" and not as "Nome" as I'd like it to be. I also have

config.i18n.default_locale = :pt_br

in my environment.rb

What is missing?

Answer 1

You can try <%= f.label :name, t('activerecord.attributes.name') %>.

Answer 2

I think you need to namespace your attributes under user. i.e.:

pt_br:
  activerecord:
    attributes:
      user:
        name: "Nome"
        address: "Endereço"

And you can install the i18n_label plugin to automatically translate the labels.
