Pankuzu

Pankuzu generates breadcrumbs html. (Pankuzu means bread-crumbs in Japanese.)

Put on breadcrumbs helper in your view file.

app/views/layouts/application.html.erb:

<%= render "breadcrumbs" %>

Add breadcrumb each views.

app/views/posts/show.html.erb:

<%
add_breadcrumb "Home",          root_path
add_breadcrumb "Listing Posts", posts_path
add_breadcrumb "A Post",        @post
%>

breadcrumbs helper puts html below.

<ol class="breadcrumbs">
  <li class="breadcrumb"><a href="/">Home</a></li>
  <li class="breadcrumb"><a href="/posts">Listing Posts</a></li>
  <li class="breadcrumb"><a href="/posts/12345">A Post<a></a></li>
</ol>

Add this line to your application's Gemfile:

gem "pankuzu"

And then execute:

$ rails generate pankuzu:install

This generator creates _breadcrumbs.html.erb in app/views/application directory.
