HasSecureToken

HasSecureToken provides you an easily way to geneatre uniques random tokens for any model in ruby on rails. SecureRandom::base58 is used to generate the 24-character unique token, so collisions are highly unlikely.

Note that it's still possible to generate a race condition in the database in the same way that validates_uniqueness_of can. You're encouraged to add a unique index in the database to deal

Installation

Add this line to your application's Gemfile:

gem 'has_secure_token'

And then execute:

$ bundle

Or install it yourself as:

$ gem install has_secure_token

Setting your Model

The first step is to run the migration generator in order to add the token key field.

rails g migration AddTokenToUsers token:string
=>
   invoke  active_record
   create    db/migrate/20150424010931_add_token_to_users.rb

Then need to run rake db:migrate to update the users table in the database. The next step is to update the model code

# Schema: User(token:string, auth_token:string)
class User < ActiveRecord::Base
  has_secure_token
end

user = User.new
user.save
user.token # => "4kUgL2pdQMSCQtjE"
user.regenerate_token # => true

To use a custom column to store the token key field you can use the column_name option.

# Schema: User(token:string, auth_token:string)
class User < ActiveRecord::Base
  has_secure_token :auth_token
end

user = User.new
user.save
user.auth_token # => "4kUgL2pdQMSCQtjE"
user.regenerate_auth_token # => true
