has_tokens

Creates tokens for accessing ActiveRecord objects. Allows you to declaratively specify token-based access for your ActiveRecord objects.

Under the covers, has_tokens uses SecureRandom.hex so they'll be all "c07a2". The size is configurable, so if you need a token that is trillions of characters long, you can make that happen, man.

Install

gem install has_tokens

Active Record Implementation

Create a Migration to add a string "public_token" to your model
Index that public_token field

class YourSuperActiveRecordClass < ActiveRecord::Base
  HasTokens.on self
  has_tokens public: 5

  before_validation :generate_tokens, on: :create
  validates_uniqueness_of :public_token

  def self.for_token(token)
    find_by_public_token!(token)
  end

  def to_param
    public_token
  end
end

Now, your urls will be tokenized "/models/5245c"

Note, if you have a bunch of models, you'll want to generate tokens for each using generate_tokens (and then save the model).

So, you first include has_tokens in your class with HasTokens.on self. Then, the has_tokens will define your public_token method.

PORO (ruby object) Implementation

class YourHipsterClass
  HasTokens.on self
  has_tokens public: 5
  def initialize
    generate_tokens
  end
end

You know, or whatever.
