Correct way to create form that accepts multiple locales

[jboler]

Am I correct in thinking this gem is helping accomplish something like the code below that currently works for me? If so is this my of creating a form for different locales deprecated?

In model

accepts_nested_attributes_for :translations

In a haml form view:

  - [:en, :es, :fr].each do |lan|
    = f.globalize_fields_for lan do |j|
      = j.text_field :name

In lib:

module ActionView
  module Helpers
    class FormBuilder
      def globalize_fields_for(locale, *args, &proc)
        raise ArgumentError, "Missing block" unless block_given?

        @index = @index ? @index + 1 : 1

        object_name = "#{@object_name}[translations_attributes][#{@index}]"
        object = @object.translations.find_by_locale locale.to_s

        @template.concat @template.hidden_field_tag("#{object_name}[id]", object ? object.id : "")
        @template.concat @template.hidden_field_tag("#{object_name}[locale]", locale)

        if @template.respond_to? :simple_fields_for
          @template.simple_fields_for(object_name, object, *args, &proc)
        else
          @template.fields_for(object_name, object, *args, &proc)
        end
      end
    end
  end
end

Your solution is not "deprecated", it's just that this gem provides nice and short api for the field names and predefined locales.

Actually I was thinking of creating a simple gem to make it easy to create forms, but that's really separate from this gem. I'm closing this, if I ever get around to it I'll mention it here.
