Provides an easy_breadcrumbs view helper for automatically generating bootstrap breadcrumbs for your Sinatra Application.

• It's able to properly generate the html for many different types of complex routes (See Below).
• It only generates breadcrumbs for the routes you've defined, so if you have a route /categories/10/contacts/5, but haven't defined an index view route for /categories, that item will be left out.
• It can automatically detect certain name attributes for specific resources.

Add this line to your application's Gemfile:

gem 'easy_breadcrumbs'

And then execute:

$ bundle

Or install it yourself as:

$ gem install easy_breadcrumbs

If you're building a classic style Sinatra app, simply add this line to your sinatra application file:

require "easy_breadcrumbs"

If you're building a modular style Sinatra app, you'll also need to explicitly register the module within your application.

class HelloApp < Sinatra::Base
  helpers Sinatra::EasyBreadcrumbs

  get "/hello" do
    h "1 < 2"
  end
end

And then use the helper method in your layout or view:

<%= easy_breadcrumbs %>

And last but not least, make sure you have bootstrap installed. You can install bootstrap's css by adding this line to your applications layout template.

NEW: Auto Name Detection

Easy Breadcrumbs can now detect names for specific resources.

Path: /contacts/10
Old Breadcrumb Format: Home > Contacts > Contact
New Breadcrumb Format: Home > Contacts > Ada Lovelace

It's able to detect the name with the following limitations:

• The resource is either a Hash or a Custom object
• The resource has a key (Hash) or accessor method (custom object) of one of the following 3 commonly used name attributes:
  • :name
  • :title
  • :subject

If this condition fails, it will default to the old format.

Easy Breadcrumbs is able to handle a variety of complex routes.

Here are some examples:

Path: /about
Breadcrumb: Home > About

Path: /contacts
Breadcrumb: Home > Contacts

###Path to specific resource

Path: /contacts/28
Breadcrumb: Home > Contacts > Contact

Path: /contacts/new
Breadcrumb: Home > Contacts > New Contact

Path: /contacts/28/edit
Breadcrumb: Home > Contacts > Contact > Edit Contact

Path: /categories/5/contacts
Breadcrumb: Home > Categories > Category > Contacts

Path: /categories/5/contacts/10
Breadcrumb: Home > Categories > Category > Contacts > Contact

Path: /categories/5/contacts/new
Breadcrumb: Home > Categories > Category > Contacts > New Contact

Path: /categories/5/contacts/10/edit
Breadcrumb: Home > Categories > Category > Contacts > Contact > Edit Contact

• Don't render breadcrumbs if current page is home
• Allow for manual turning off of breadcrumbs for specific routes or sets of routes
• Allow for custom configuration of name attributes for resources
  • Should be able to do something like set :easy_breadcrumbs, user: :name, post: :title
• More robust spec suite
  • Explore more edge cases for both unit and integration tests
  • Eliminate repetition in specs
  • Other development gems that would help with this?
• Update gemspec with depencency version restrictions and bump gem version to 1.0
