Question

I am trying to create a translatable successful notice. This notice would be called by a successful call of the create and update actions.

This is what I have so far:

#config/locales/en.yml
activerecord:
  models:
    place: "Place"
  successful:
    messages:
      created: "%{model} was successfully created."
      updated: "%{model} was successfully updated."

#app/controllers/places_controller.rb
def create
  ...
  format.html { redirect_to(@place, :notice => "#{t 'activerecord.successful.messages.created'}") }

The problem is that this shows the message: “%{model} was successfully created.”. How do I get it to say: “Place was successfully created.”?

You need to use i18n’s interpolation functions (see http://guides.rubyonrails.org/i18n.html#interpolation) do do something like

t('activerecord.successful.messages.created', :model => @my_newly_saved_object.class.model_name.human) 

where model_name returns the name of the class of the created object (see http://api.rubyonrails.org/classes/ActiveModel/Name.html). calling human on this object returns the i18n translation of the model name (from the scope activerecord.models.{model_name})
