Ruby on Rails User Authentication in Rails has_secure_token
Example
Create User Model
# Schema: User(token:string, auth_token:string)
class User < ActiveRecord::Base
has_secure_token
has_secure_token :auth_token
end
Now when you create a new user a token and auth_token are automatically generated
user = User.new
user.save
user.token # => "pX27zsMN2ViQKta1bGfLmVJE"
user.auth_token # => "77TMHrHJFvFDwodq8w7Ev2m7"
You can update the tokens using regenerate_token and regenerate_auth_token
user.regenerate_token # => true
user.regenerate_auth_token # => true
