Breadcrumb

Put the following line in your Gemfile

gem 'breadcrumb'

And then execute:

$ bundle

Layout: <%= breadcrumb %>

You can add a root path by doing this

<%= breadcrumb.prepend("Home","/") %>

In your view (say the uri path is /books/religion/the-holly-bible):

  <%
  breadcrumb.add("Books","/books")
  breadcrumb.add("Religion", books_category_path(@book.category))
  breadcrumb.add(@book.title)
  %>

It will render

  <div class="breadcrumb">
    <a href="/books">Books</a>
    <span class="separator"> » </span>
    <a href="/books/religion">Religion</a>
    <span class="separator"> » </span>
    <span>The Holly Bible</span>
  </div>

You can change the separator

<% breadcrumb.separator = '<span class="separator"> &gt; </span>' %>

Titleizing You can use breadcrumb for creating the page title:

  <title><%= breadcrumb.titleize %></title>

which will ouput

  <title>Books :: Religion :: The Holly Bible</title>

Titleize accepts block. When using blocks, returning false removes the title part. Returing nil, won't change the behavior. Returning String changes the title part.

  <title><%= breadcrumb.titleize {|part| "Our Awesome Books" if parts == 'Books' } %></title>

Ouputs

  <title>Our Awesome Books :: Religion :: The Holly Bible</title>

Removing the title part

  <title><%= breadcrumb.titleize {|part| false if part == "Religion" } %></title>
<!-- or -->
  <title><%= breadcrumb.titleize {|part, order| false if order == 1 } %></title>

Outputs

  <title>Books :: The Holly Bible</title>

And you can change the title separator:

<% breadcrumb.title_separator = '-' %>
