# Localization (i18n)

Localization is a Pro feature

Avo leverages Rails powerful I18n translations module. When you run bin/rails avo:install Rails will generate for you the avo.en.yml translation file. This file will automatically be injected into the I18n translations module.

# Localizing resources

Let's say you want to localize a resource. All you need to do is add a self.translation_key class attribute in the Resource file. This will tell Avo to use that translation key to localize this resource. This will change the labels of that resource everywhere in Avo.




 


# app/avo/resources/user_resource.rb
class UserResource < Avo::BaseResource
  self.title = :name
  self.translation_key = 'avo.resource_translations.user'
end





 
 
 
 
 

# avo.es.yml
es:
  avo:
    dashboard: 'Dashboard'
    # ... other translation keys
    resource_translations:
      user:
        zero: 'usuarios'
        one: 'usuario'
        other: 'usuarios'

# Localizing fields

Similarly, you can even localize fields. All you need to do is add a translation_key: option on the field declaration.







 


# app/avo/resources/project_resource.rb
class ProjectResource < Avo::BaseResource
  self.title = :name

  field :id, as: :id
  # ... other fields
  field :files, as: :files, translation_key: 'avo.field_translations.file'
end





 
 
 
 
 

# avo.es.yml
es:
  avo:
    dashboard: 'Dashboard'
    # ... other translation keys
    field_translations:
      file:
        zero: 'archivos'
        one: 'archivo'
        other: 'archivos'

# Setting the locale

Setting the locale for Avo is simple. Just use the config.locale = :en config attribute. Default is nil and it will fallback to whatever you have configured in application.rb.


 


Avo.configure do |config|
  config.locale = :en # default is nil
end

This will change the locale only for Avo requests. The rest of your app will still use your locale set in application.rb. If you wish to change the locale for the whole app you can use the set_locale=pt-BR param. That will set the default locale until you restart your server.

If you wish to change the locale only for one request use the force_locale=pt-BR param. This will set the locale for that request and will keep the force_locale param while you navigate Avo. Remove that param when you want to go back to your configured default_locale.

Check out our guide for multilingual records.

# Re-generate the locale

When updating Avo please run bin/rails generate avo:locales to re-generate the locales file.

# FAQ

If you try to localize your resources and fields and it doesn't seem to work please be aware of the following.

# Advanced localization is a Pro feature

Localizing strings in Avo will still work using Rails' I18n mechanism, but localizing fileds and resources require a Pro or above license.

The reasoning behind this is that deep localization is a more advanced feature that usually falls in the commercial realm. If you create commercial products or apps for clients, and make revenue using Avo, we'd love to get your support to be able to maintain it and ship new features going forward.

# The I18n.t method defaults to the name of that field/resource

Internally the localization works like so I18n.t(translation_key, count: 1, default: default) where the default is the computed field/resource name. So check the structure of you translation keys.

# config/locales/avo.pt-BR.yml
pt-BR:
  avo:
    field_translations:
      file:
        zero: 'arquivos'
        one: 'arquivo'
        other: 'arquivos'
    resource_translations:
      user:
        zero: 'usuários'
        one: 'usuário'
        other: 'usuários'
