ActsAsHashed

ActsAsHashed is helpful to set a hash_code column based on SecureRandom.hex(16).

Installation

Add this line to your application's Gemfile:

gem 'acts_as_hashed'

And then execute:

$ bundle

Or install it yourself as:

$ gem install acts_as_hashed

Usage

Create your migrations for the desired models

$ rails g migration AddHashedCodeToOrders hashed_code:string

or

class AddHashedCodeToOrders < ActiveRecord::Migration
  def self.up
    add_column :orders, :hashed_code, :string
  end

  def self.down
    remove_column :orders, :hashed_code, :string
  end
end

Usage

In your model:

class Order < ActiveRecord::Base
  acts_as_hashed

  def to_param
    hashed_code
  end

  ...
end

or you can overwrite the method that will generate the hash.

class Order < ActiveRecord::Base
  acts_as_hashed

  class << self
    def friendly_token
      SecureRandom.hex(5)
    end
  end
end

If you are adding acts_as_hashed after having some records on your database you need too run the code above to update the records:

Order.update_missing_hashed_code
