Instance Method Details

Declare and populate a navigation bar. This method is a shorthand for creating a before_filter that looks up and populates a navigation bar.

Examples:

nav_bar :tabs, :only => [:index, :sent, :received, :new] do |nb|
  nb.nav_item :received, received_messages_path(current_user)
  nb.nav_item :sent,     sent_messages_path(current_user)
  nb.nav_item :new,      new_message_path
end

Parameters:

  • name (String, Symbol) (defaults to: Xebec::NavBar::DEFAULT_NAME) —

    the name of the navigation bar; optional

  • options (Hash) (defaults to: {}) —

    the options for the before_filter; optional.

Yields:

  • (Xebec::NavBar) —

    nav_bar the navigation bar – NB: does NOT yield at call-time, but at action run-time, as a before filter. The block is evaluated in the scope of the controller instance.

Returns:

  • (nil)
