# Don't forget to run `rake db:migrate`!

step_3.markdown

Override view=admin/pages/_locale_picker; copy it into app/views/shared/admin/ (may need to mkdir -p here)

step_4.rb

# Override view=admin/<model>/_form and edit it. After the following:


<%= form_for [:admin, @<model>], url_opts do |f| %>

  <%= render :partial => "/shared/admin/error_messages",
             :locals => {
               :object => @<model>,
               :include_object_name => true
             } %>


# Insert...

  <%= render :partial => "/shared/admin/locale_picker",
             :locals => {
               :current_locale => Thread.current[:globalize_locale]
             } if ::Refinery.i18n_enabled? %>

step_5.rb

# Override view=admin/<model>/_<model> and edit it. Change the top bit to look something like this:

<span class='title'>
  <%= <model>.name %>
  <% if ::Refinery.i18n_enabled? and ::Refinery::I18n.frontend_locales.many? and (locales = <model>.translations.map(&:locale)).present? %>
  <span class='preview'>
    <% ([<model>.translation.try(:locale)] | locales).each do |locale| %>
    <%= link_to refinery_icon_tag("flags/#{locale}.png", :size => '16x11'), edit_admin_<model>_path(<model>, :switch_locale => locale), :class => 'locale' %>
    <% end %>
  </span>
  <% end %>
</span>

Some notes for Refinery 2.0.x

Step 1 - drop_column isn't valid - should be remove_column

Step 2 - model needs:

  class Translation
    attr_accessible :locale
  end
