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 and works with non-Latin characters.
Add mongoid_slug to your Gemfile:
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 end
In 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 for all available options.
To scope a slug by a reference association, pass
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 end
In 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
: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
