原标题:Adding token_authenticatable to devise with migration

我已经采用了设计方法建立了用户模型,但我现在要为象征性的——可以理解的——提供更多支持,因此,我需要迁移这些增补内容。 下述情况是否正确,以及应当证明什么类型?

class AddAuthenticationTokenToUser < ActiveRecord::Migration

  def change

    add_column :users, :token_authenticatable
    add_index  :users, :authentication_token, :unique => true

  end

end
最佳回答

devise 2.0 generator (line 74) on Github:

# t.string :authentication_token

如果你要根据他们的表象来研究用户,那么增加指数是一个好的想法。

这里设计1.5个文件

问题回答
add_column :users, :token_authenticatable, :string

Don tabe 增加devise :token_authenticatable至您的用户模型。

在设计2中,删除的移民帮助者名单如下:

create_table(TABLE_NAME) 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

  ## Invitable
  # t.string :invitation_token

  t.timestamps
end
