tokenize

tokenize generates unique strings for ActiveRecord models before creation. This works well for setting API keys, temporary passwords, etc. tokenize is also great for creating forward-facing IDs for models such as products or orders where you may not want to use the numeric primary key and reveal your volume.

Installation

script/plugin install git://github.com/laserlemon/tokenize.git

Example

In your migration:

create_table :users do |t|
  t.string :first_name
  t.string :last_name
  t.string :token, :limit => 8
  t.timestamps
end

In your model:

class User < ActiveRecord::Base
  validates_presence_of :first_name, :last_name

  tokenize
end

In your controller:

user = User.create(:first_name => 'Steve', :last_name => 'Richert')

Tips

• You can pass multiple token columns into the tokenize or omit the column names to use the default (:token).

• You can pass :length and :characters options to the tokenize method for finer control over the token format. The default is an 8-character string of lowercase and uppercase letters as well as numbers, producing 218,340,105,584,896 possible tokens.
