Ruby on Rails: i18n form labels

In Rails <=2.3 i18n internationalization does not include translation of form labels. However, this can be easily fixed by installing the patch i18n_label by iain. For your Rails project, just install plugin:

ruby script/plugin install git://github.com/iain/i18n_label.git

Now you should just add appropriate entries to your locale file. I’d explain it in the example below.
I have the following form to the model Post:

<% form_for :post do |f| -%>
  <%= f.error_messages %>

  <p><%= f.label :name %></p>
  <p><%= f.text_field :name %></p>

  <p><%= f.submit "Wyślij" %></p>
<% end -%>

I want the label :name to be automatically translated according to the entry in locales. Taking as an example polish locale pl.yml, we have to create new entry:

pl:
  activerecord:
    models:
      post: "Wiadomości"
    attributes:
      post:
        name: "Nazwa"

…and that’s all! After restarting the project, the form labels are successfully tanslated according to locale entries!
