Gem devise set multiple user model system - ruby-on-rails

Question

In my app i need to do two way-login system:
1) User - only for user part of website, contain's information about user's, it's login data, etc...
2) Admin - another model for admin part of website.
But how to do this?
Now i have only first part, and my migration:
class DeviseCreateUsers < ActiveRecord::Migration
def self.up
create_table(:users) do |t|
## Database authenticatable
t.string :email, :null => false, :default => ""
t.string :encrypted_password, :null => false, :default => ""
## Recoverable
t.string :reset_password_token
t.datetime :reset_password_sent_at
## Rememberable
t.datetime :remember_created_at
## Trackable
t.integer :sign_in_count, :default => 0
t.datetime :current_sign_in_at
t.datetime :last_sign_in_at
t.string :current_sign_in_ip
t.string :last_sign_in_ip
## Encryptable
# t.string :password_salt
## Confirmable
#t.string :confirmation_token
#t.datetime :confirmed_at
#t.datetime :confirmation_sent_at
#t.string :unconfirmed_email # Only if using reconfirmable
## Lockable
#t.integer :failed_attempts, :default => 0 # Only if lock strategy is :failed_attempts
#t.string :unlock_token # Only if unlock strategy is :email or :both
#t.datetime :locked_at
## Token authenticatable
t.string :authentication_token
t.timestamps
end
add_index :users, :email, :unique => true
add_index :users, :reset_password_token, :unique => true
#add_index :users, :confirmation_token, :unique => true
#add_index :users, :unlock_token, :unique => true
add_index :users, :authentication_token, :unique => true
end
def self.down
drop_table :users
end
end
And route:
devise_for :users
But how to add second admin-login part?

Answer 1

You have 3 options:
Add string field type to your table and derive from User model (the admin and user will have the same login route).
Add boolean field admin and use i.e. CanCan gem.
Run rails g devise admin and have separate admin model.
The way you choose depends on your app struct.
