Aliases for routes.rb

# The following initializer provides an :alias => "my_route_name" option to restful routes in your
# route.rb. This simply makes the same route also available under a different …_path / …_url helpers.

# For example,

# map.resources :notes, :alias => :snippets

# Gives you

# notes_path, notes_url, new_note_path... #as always
# snippets_path, snippets_url, new_snippet_path... #from the alias

# Put this into an initializer:

module ActionController::Resources

  def resources_with_alias(*args, &block)
    name = args.first
    options = args.last || {}
    name_alias = options.delete(:alias)
    resources_without_alias(*args, &block)
    if name_alias
      resources_without_alias(name_alias, options.merge(:controller => "#{options[:namespace]}#{name}", :as => name))
    end
  end

  alias_method_chain :resources, :alias

  def resource_with_alias(*args, &block)
    name = args.first
    options = args.last || {}
    name_alias = options.delete(:alias)
    resource_without_alias(*args, &block)
    if name_alias
      resource_without_alias(name, options.merge(:controller => "#{options[:namespace]}#{name}", :as => name))
    end
  end

  alias_method_chain :resource, :alias
