A Rails plugin which extends ActiveRecord using the decorator pattern to allow self-referential models (eg. acts_as_tree) to maintain a textual path representing itself and its ancestors.

gem install path_finder

h3. Example

In association with a catch-all route you can find a record using the URL:

Hierarchy -> Generated Path

# Categories -> /categories

## Books -> /categories/books

### Hardback -> /categories/books/hardback

### Paperback -> /categories/books/paperback

## Websites -> /categories/websites

	

Example URL: http://mywebsite.co.uk/categories/books/hardback

	

_category_controller.rb_

def show

  @category = Category.find_by_path(request.path)

end

_category.rb_

class Category < ActiveRecord::Base

  acts_as_tree

  path_finder :column => 'path', :uid => 'to_param', :deliminator => '/'

	def to_param

		permalink

	end

end

h3. Notes

The model must respond_to 'children'
