Mongoid Slug generates a URL slug or permalink based on one or more fields in a Mongoid model. It sits idly on top of [stringex] 1 and works with non-Latin characters.
Add mongoid_slug to your Gemfile:
gem 'mongoid_slug'Set up some slugs:
class Book
  include Mongoid::Document
  include Mongoid::Slug
  field :title
  embeds_many :authors
  slug :title
end
class Author
  include Mongoid::Document
  include Mongoid::Slug
  field :first
  field :last
  embedded_in :book, :inverse_of => :authors
  slug :first, :last, :as => :name
endIn your controller, use available finders:
# GET /books/a-thousand-plateaus/authors/gilles-deleuze
author = Book.find_by_slug(params[:book_id]).
              authors.
              find_by_name(params[:id])[Read here] 2 for all available options.
To scope a slug by a reference association, pass :scope:
class Company
  include Mongoid::Document
  references_many :employees
end
class Employee
 include Mongoid::Document
 include Mongoid::Slug
 field :name
 slug  :name, :scope => :company
 referenced_in :company
endIn this example, if you create an employee without associating it with any company, the scope will fall back to the root employees collection.
Currently, if you have an irregular association name, you must
specify the :inverse_of option on the other side of the assocation.
Embedded objects are automatically scoped by their parent.
If the value of :scope is not an association, it should be the name of a field within the model itself:
class Employee
 include Mongoid::Document
 include Mongoid::Slug
 field :name
 field :company_id
 slug  :name, :scope => :company_id
end
