Mongoid::Slufigy is a gem, which helps you with generating slugs for your Mongoid models.
Add Mongoid::Slufigy to your Gemfile:
Since 0.1.0 Mongoid::Slufigy supports both Mongoid 2.x and 3.x releases (since 3.0.0.rc).
class Product include Mongoid::Document include Mongoid::Slugify field :title private def generate_slug title.parameterize end end
As you can see, you should make 2 things:
include Mongoid::Slugify module to your model
provide a way to generate initial slug for your model (based on any fields, that you want)
If do those - Mongooid::Slugify will save the generated slug to `slug` field of your model and will care about slug uniqueness (it will append “-1”, “-2”, etc to your slugs until it finds free one).
Mongooid::Slugify gives you these additional functions:
redefines to_param method, so that it returns slug, if it's present, and model id otherwise
Model.(find_by_slug/find_by_slug!/find_by_slug_or_id/find_by_slug_or_id!) methods. If you don't want to generate slugs for all your existing objects (so that to_param will return model ids) - you should prefer the latter two in your controllers.
This library will NEVER (at least not in the nearest future) provide a way to generate initial slugs. I just don't need it. Don't try to add this functionality to my library.
If you need all-out-of-the-box solution - look at Mongoid Slug [github.com/hakanensari/mongoid-slug], it's far more full featured and actively developed.
