Localisation of attributes in Rails virtual models

I've created a virtual (non-persistent) model in Rails 3 (see below)

I now need to apply translations to the model but the standard translations locations don't seem to work. e.g.

en:
  activerecord:
    attributes:
      media_upload:
        title: "My Title"

I know I can apply this directly to the label with an optional string parameter eg. f.label :title, t('activerecord.attributes.media_upload') but that doesn't work for error messages resulting from validations. Similarly, I could add a key to the translations file for the label helper as suggested in Localise nested virtual attribute in Rails but this also fails to work for the validations.

helpers:
  label:
    media_upload:
      title: "My Title"

Apart from redefining all of the relevant validation messages, is there any other way I can do localisation of attributes in non-persistent models??

A sample model is shown below,

class MediaUpload
  include ActiveModel::Validations
  include ActiveModel::Conversion
  extend ActiveModel::Naming

  attr_accessor :media_file, :title

  validates_presence_of :media_file
  validates_presence_of :title

  def initialize(attributes = {})
    unless attributes.nil?
      attributes.each do |name, value|
        send("#{name}=", value)
      end
    end
  end

  def persisted?
    false
  end
end

It seems like you are using simple_form gem for generation of forms.

So following i18n chapter from github your internationalization file should look like this

en:
  simple_form:
    labels:
      media_upload:
        media_file: My File
        title: My Title

If you are using Rails 4 than there is an easier way to make ActiveModel Form Objects. You can just include ActiveModel::Model like so

class MediaUpload
  include ActiveModel::Model

  attr_accessor :media_file, :title

  validates_presence_of :media_file
  validates_presence_of :title
end

You need write like this:

en:
  activemodel:
    attributes:
      media_upload:
        title: "My Title"

not activerecord replace it with activemodel
