#
# Helper that renders translations fields
# on a per-locale basis, so you can use them separately
# in the same form and still saving them all at once
# in the same request.
#
# Use it like this:
#
# <h1>Editing post</h1>
#
# <% form_for(@post) do |f| %>
# <%= f.error_messages %>
#
# <h2>English (default locale)</h2>
# <p><%= f.text_field :title %></p>
# <p><%= f.text_field :teaser %></p>
# <p><%= f.text_field :body %></p>
#
# <hr/>
#
# <h2>Spanish translation</h2>
# <% f.globalize_fields_for :es do |g| %>
# <p><%= g.text_field :title %></p>
# <p><%= g.text_field :teaser %></p>
# <p><%= g.text_field :body %></p>
# <% end %>
#
# <hr/>
#
# <h2>French translation</h2>
# <% f.globalize_fields_for :fr do |g| %>
# <p><%= g.text_field :title %></p>
# <p><%= g.text_field :teaser %></p>
# <p><%= g.text_field :body %></p>
# <% end %>
#
# <% end %>
