def i18n_default_scope(*path)
  options = path.extract_options!
  options[:as] ||= :t_scoped
  path << options
  i18n_scope(:default, *path)
end

#i18n_scope(name, *path) ⇒ Object

Use this method to configure how the scope will be built when using translations

Params:

  • path: Either a single String or Symbol, or an Array of Symbols and Strings

  • options: options to be used within this class, they will overwrite the configuration made in Configuration

    • :plural_classes: if the class name should be pluralized or singularized

    • :strip_controller_suffix: if the _controller suffix of classes should be stripped or not

Usage:

i18n_scope :flash, :modules, :class_name, :action_name, :custom_value, "static_prefix", :plural_classes => true, :strip_controller_suffix => true

this will create a t_flash method

with a Tweets::PostsController, the action index and a custom_value method that returns a_value this will led to the following scope:

[:tweets, :posts, :index, :a_value, "static_prefix"]
