Mongo ids leads to scary URLs
You can create a composite key in mongoid to replace the default id using the key macro:
class Person include Mongoid::Document field :first_name field :last_name key :first_name, :last_nameendperson = Person.new(:first_name => "Syd", :last_name => "Vicious")person.id # returns "syd-vicious"If you don't like this way to do it, check this gem: https://github.com/hakanensari/mongoid-slug
Define a friendly unique field (like a slug) on your collection, index it, on your model, define to_param to return it:
def to_param slugendThen in your finders, find by slug rather than ID:
@post = Post.where(:slug => params[:id].to_s).firstThis will let you treat slugs as your effective PK for the purposes of resource interaction, and they're a lot prettier.
