module I18nMultitenant

Public: Configures an instance of I18n::Config to ensure fallbacks are setup.

# File lib/i18n_multitenant.rb, line 47
def self.configure(config, enforce_available_locales: false)
  config.enforce_available_locales = enforce_available_locales
  config.backend.class.send(:include, I18n::Backend::Fallbacks)

  if defined?(Rails.root)
    config.load_path += Dir[Rails.root.join('config', 'locales', '**', '*.{rb,yml}')]
  end
end

Internal: Get the internal locale for a tenant-specific locale.

Example:

I18nMultitenant.locale_for(locale: :en, tenant: 'Veridian Dynamics')
=> "en-VERIDIAN_DYNAMICS"

# File lib/i18n_multitenant.rb, line 38
def self.locale_for(locale: I18n.default_locale, tenant: nil)
  if tenant && !tenant.to_s.empty?
    "#{ locale }-#{ tenant.to_s.upcase.tr(' .-', '_') }"
  else
    locale
  end
end

Public: Sets the internal locale to consider the current tenant and base locale.

locale: The base locale to be set (optional: uses the default locale). tenant: Name of the current tenant (optional: does not scope to the tenant).

Returns the key that should be used for all translations specific to that locale and tenant configuration.

Example:

I18nMultitenant.set(locale: :en, tenant: 'Veridian Dynamics')
=> "en-VERIDIAN_DYNAMICS"

I18nMultitenant.set(locale: 'en-GB', tenant: :'strange.tenant-name')
=> "en-GB-STRANGE_TENANT_NAME"

I18nMultitenant.set(locale: :es)
=> :es

# File lib/i18n_multitenant.rb, line 23
def self.set(options)
  I18n.locale = locale_for(options)
end

Public: Executes block using the specified locale configuration, restoring it after the block is executed.

# File lib/i18n_multitenant.rb, line 29
def self.with_locale(options)
  I18n.with_locale(locale_for(options)) { yield }
end
