# SimpleBreadcrumbs

This gem provides a simple and flexible way to create breadcrumbs with Rails active record 
models. Setting `has_breadcrumb` on a model will enable a view method,
`breadcrumb()`, which will show the links to the page and its parents in
a breadcrumb format.

## Installation

Add this line to your application's Gemfile:

    gem 'simple_breadcrumbs'

And then execute:

    $ bundle

## Usage

In your model:

    class User < ActiveRecord::Base
      has_breadcrumb :title => :username
    end

To display a model as a child of another model, you state the parent
by using the `:parent` parameter:

    class UserProfile < ActiveRecord::Base
      has_breadcrumb :parent => :user, :title => "Profile"
    end

As can be seen here, `has_breadcrumb` can accept a `String` on the
`:title` option, which is useful in the case where there is no field in
the model which would be suitable. The `:parent` option however, must
take a `Symbol`.

Breadcrumb links are displayed in a view by including the `breadcrumb` erb tag. 
For example in an erb view for creating a new user,

    <h2 class="subtitle"><%= breadcrumb @user, 'New' %></h2>

will provide a link which includes the Index page and the controller
action to which this page is related.

Other options allowed by the `breadcrumb` method include
`:forced_parent`, which links to a non-natural parent of the current
view page.

By default, `breadcrumb` includes a link to the index of an object when only
one level exists.
