Breadcrumbs is a simple plugin that adds a breadcrumbs object to controllers and views.
Just run sudo gem install breadcrumbs
On your controller (optional):
class ApplicationController < ActionController::Base before_filter :add_initial_breadcrumbs private def .add 'Home', root_path end end class ThingsController < ApplicationController def index .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:
.add 'Some page'
You can set additional HTML attributes if you need to:
.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 ::::Dl def render # return breadcrumbs wrapped in a <DL> tag end end
To use your new format, just provide the :format option.
.render(:format => :dl)
Breadcrumbs is integrated with I18n. You can set translations like:
en: breadcrumbs: home: "Home"
And then you just call
In fact, you can provide any scope you want.
If you don't want to translate a label, just pass the option :i18n as false.
.add :home, nil, :i18n => false
