How to localize your app

The first thing that you need to do is to set your locale by appending it to boot.rb:

# config/boot.rb
Padrino.before_load do
  I18n.locale = :de

By default Padrino will search for all .yml or .rb files located in app/locale; as an example try to add the following to your app/locale/de.yml:

in your view or controller or wherever you prefer add:


you will get:

=> "Bar"

Translate Models (ActiveRecord)

Translating models via Padrino requires few seconds thanks to a builtin rake task!

Assuming the following Account model:

create_table :accounts do |t|
  t.string   :name
  t.string   :surname
  t.string   :email
  t.string   :salt
  t.string   :crypted_password
  t.string   :role

add this to your boot.rb (or anywhere else):

# config/boot.rb
Padrino.before_load do
  I18n.locale = :it

run padrino rake task for localizing your model:

padrino rake ar:translate

a new it.yml file will be created into /app/locale/models/account/it.yml with the following:

you can now edit your generated it.yml file to reflect your current locale (Italian):

padrino-admin will now use your newly created yml file for translating the column names of grids, forms, error_messages etc…



Using form_builder like:

-form_for :account, url(:accounts_create, :format => :js), :remote => true do |f|
      %td=f.label :name
      %td=f.text_field :name
      %td=f.label :surname
      %td=f.text_field :surname
      %td=f.label :role :role, :options => access_control.roles

the tag label automatically translates for you the field name!!
