Breadcrumbs

Breadcrumbs is a simple plugin that adds a breadcrumbs object to controllers and views.

Instalation

Just run sudo gem install breadcrumbs

Usage

On your controller (optional):

class ApplicationController < ActionController::Base
  before_filter :add_initial_breadcrumbs

  private
  def add_initial_breadcrumbs
    breadcrumbs.add 'Home', root_path
  end
end

class ThingsController < ApplicationController
  def index
    breadcrumbs.add 'Things', things_path
  end
end

You don't need to provide an URL; in that case, a span will be generated instead of a link:

breadcrumbs.add 'Some page'

You can set additional HTML attributes if you need to:

breadcrumbs.add 'Home', root_path, :id => 'home', :title => 'Go to the home page'

On your view (possibly application.html.erb):

<%= breadcrumbs.render %>

You can render as ordered list.

<%= breadcrumbs.render(:format => :ordered_list) %>

You can render as inline links.

<%= breadcrumbs.render(:format => :inline) %>

You can set your own separator:

<p>
  You are here: <%= breadcrumbs.render(:format => :inline, :separator => '|') %>
</p>

You can also define your own formatter. Just create a class that implements a render instance method and you're good to go.

class Breadcrumbs::Render::Dl
  def render
    # return breadcrumbs wrapped in a <DL> tag
  end
end

To use your new format, just provide the :format option.

breadcrumbs.render(:format => :dl)

I18n

Breadcrumbs is integrated with I18n. You can set translations like:

en:
  breadcrumbs:
    home: "Home"

And then you just call

breadcrumbs.add :home

In fact, you can provide any scope you want.

breadcrumbs.add "titles.home"

If you don't want to translate a label, just pass the option :i18n as false.

breadcrumbs.add :home, nil, :i18n => false
