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, supporting non-Latin characters.
Add to your Gemfile:
gem 'mongoid_slug'Set up a slug:
class Book
include Mongoid::Document
include Mongoid::Slug
field :title
slug :title
endFind a record by its slug:
# GET /books/a-thousand-plateaus
book = Book.find_by_slug params[:book_id][Read here] 4 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
referenced_in :company
slug :name, :scope => :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.
The value of :scope can alternatively be a field within the model itself:
class Employee
include Mongoid::Document
include Mongoid::Slug
field :name
field :company_id
slug :name, :scope => :company_id
endTo specify that the history of a document should be kept track of, pass
:history with a value of true.
class Page
include Mongoid::Document
include Mongoid::Slug
field :title
slug :title, history: true
endThe document will then be returned for any of the saved slugs:
page = Page.new title: "Home"
page.save
page.update_attributes title: "Welcome"
Page.find_by_slug("welcome") == Page.find_by_slug("home") #=> truePass words you do not want to be slugged using the reserve option:
class Friend
include Mongoid::Document
field :name
slug :name, reserve: ['admin', 'root']
end
friend = Friend.create name: 'admin'
Friend.find_by_slug('admin') # => nil
friend.slug # => 'admin-1'
