Why expose your public ID's if you don't need to? Hang hash_identable on your rails models and use the #uuid method to get a unique id of any item.
This gem wraps the hashids.org ruby gem: http://hashids.org/ruby/
Add this line to your application's Gemfile:
gem 'hash_identable', :git => 'https://github.com/octaviuslabs/hash_identable.git'
And then execute:
$ bundle
Assuming your model
class MyModel
attr_reader :id #HashIdentable depends on the presence of an ID
# Other code
end
Configure the gem
HashIdentable.config do |c|
c.set_salt "My Salt" #THIS VALUE SHOULD NEVER CHANGE FOR THE APPLICATION
c.set_length 36
c.add_object MyModel, 3
end
When you want the hashid:
obj = MyModel.new(id: 12)
obj.uuid
Or:
obj = MyModel.new(id: 12)
obj.identity.to_s
When you want to find an object based on the hashid:
obj = HashIdentable::Locator.find([<find_method>], id) # Non ActiveRecord
obj = HashIdentable::Locator::ActiveRecord.find(id) #ActiveRecord
