Breadcrumbs On Rails

BreadcrumbsOnRails is a simple Ruby on Rails plugin for creating and managing a breadcrumb navigation for a Rails project. It provides helpers for creating navigation elements with a flexible interface.

Requirements

  • Rails 3

Please note

  • BreadcrumbsOnRails 2.x requires Rails 3. Use BreadcrumbsOnRails 1.x with Rails 2.
  • BreadcrumbsOnRails doesn't work with Rails 2.1 or lower.

Installation

RubyGems is the preferred way to install BreadcrumbsOnRails and the best way if you want install a stable version.

$ gem install breadcrumbs_on_rails

Specify the Gem dependency in the Bundler Gemfile.

gem "breadcrumbs_on_rails"

Use Bundler and the :git option if you want to grab the latest version from the Git repository.

Basic Usage

Creating a breadcrumb navigation menu in your Rails app using BreadcrumbsOnRails is really straightforward.

In your controller, call add_breadcrumb to push a new element on the breadcrumb stack. add_breadcrumb requires two arguments: the name of the breadcrumb and the target path.

class MyController

  add_breadcrumb "home", :root_path
  add_breadcrumb "my", :my_path

  def index
    # ...

    add_breadcrumb "index", index_path
  end

end

The third, optional argument is a Hash of options to customize the breadcrumb link.

class MyController
  def index
    add_breadcrumb "index", index_path, :title => "Back to the Index"
  end
end

In your view, you can render the breadcrumb menu with the render_breadcrumbs helper.

  <title>untitled</title>
</head>

<body>
  <%= render_breadcrumbs %>
</body>
</html>

render_breadcrumbs understands a limited set of options. For example, you can pass change the default separator with the :separator option.

<body>
  <%= render_breadcrumbs :separator => ' / ' %>
</body>

More complex customizations require a custom Builder.
