#globalize_fields_for(locale, *args, &proc) ⇒ Object

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 %>
