How do I add translations to an Active Model

Question

I have this model:

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

  attr_accessor :id

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

  def persisted?
    false
  end
end

How can I add i18n translations to this model? Specifically:

How do I translate its model name?
How do I translate its attributes?
How do I provide custom translation for its submit button?

I am using SimpleForm.

In your config/locales folder, create an activerecord.nl.yml (e.g. for Dutch), then in that file put the active record translations as follows

nl:
  activerecord: 
    models: 
      coupon: translation
      coupons: translation

As for the labels and buttons, create a simple-form.nl.yml file, containing

nl:
  buttons: &buttons
    submit: translation
    ...

and

  labels: &labels
    name: translation
    ...

at the end of that file, put

  simple_form:
    buttons:
      defaults:
        <<: *buttons
    labels:
      defaults:
        <<: *labels

by splitting up the list of labels and buttons from the simple form section, you can also use them elsewhere in your views

Nice trick, using variables. Nonetheless it doesn't seem to be working for me. Neither the attributes nor the model name is being translated. Here is the test code https://github.com/Nerian/i18n-test-app – Nerian Nov 24 '13 at 22:18
Also, notice that I want the custom submit translation just for one model, not for all. – Nerian Nov 24 '13 at 22:19
I don't see the simple_form code in your yml file? It is the simple form label part that takes care of the translation of the labels. For buttons, I normally use something like = f.button :submit, t('buttons.submit') – Danny Nov 25 '13 at 19:15
Mmm, I would have thought that specifying the translation for the model attributes will be enough for simple_form to figure out that it should default to those for the labels. It does work like that when I am using Mongoid. In Mongoid I can translate mongoid.attributes.book_keeping_entry.balance and Simpleform will use that for the label. – Nerian Nov 26 '13 at 15:52
Have a look at https://github.com/plataformatec/simple_form#i18n It also states that "In addition, Simple Form will fallback to default human_attribute_name from Rails when no other translation is found for labels." I think you're referring to this? I've never used that – Danny Nov 27 '13 at 07:21
