从Authlogic迁移到devise

我以前在我的网站上实施了Authlogic进行授权。 但是现在我想转而使用Devise,而且我想知道是否有人有这方面的经验。 也许有人看到关于这个主题的博客文章?

谢谢。

    我自己最近从Authlogic转到Devise,也没有find任何文章。 然而,在简单的情况下,一旦抛出所有的user_session和其他authlogic相关的代码,主要工作就是将你的旧用户表转换成devise所期望的格式。

    我的旧桌子看起来像这样:

    Column | Type | Modifiers -------------------+--------------------------+---------------------------------------------------- id | integer | not null default nextval('users_id_seq'::regclass) login | character varying(256) | not null password | character varying(64) | not null created_at | timestamp with time zone | not null updated_at | timestamp with time zone | not null persistence_token | character varying(255) | not null Indexes: "users_pkey" PRIMARY KEY, btree (id) "index_users_on_persistence_token" UNIQUE, btree (persistence_token) "users_login_key" UNIQUE, btree (login) 

    并且我确定表格必须包含至less以下devise信息(启用了许多可选function):

      id | integer | not null default nextval('contributors_id_seq'::regclass) email | character varying(255) | not null default ''::character varying encrypted_password | character varying(128) | not null default ''::character varying password_salt | character varying(255) | not null default ''::character varying confirmation_token | character varying(255) | confirmed_at | timestamp without time zone | confirmation_sent_at | timestamp without time zone | reset_password_token | character varying(255) | remember_token | character varying(255) | remember_created_at | timestamp without time zone | sign_in_count | integer | default 0 current_sign_in_at | timestamp without time zone | last_sign_in_at | timestamp without time zone | current_sign_in_ip | character varying(255) | last_sign_in_ip | character varying(255) | failed_attempts | integer | default 0 unlock_token | character varying(255) | locked_at | timestamp without time zone | created_at | timestamp without time zone | updated_at | timestamp without time zone | 

    所以我在迁移类中定义了一个未经修改的activerecord类

      class ConversionUser < ActiveRecord::Base set_table_name "users" end 

    然后这里是我最终使用的“up”迁移代码(使用PostgreSQL):

     add_column :users, :email, :string, :limit => 255 execute "UPDATE users SET email = login || '@somedomain.net'" execute "ALTER TABLE users ALTER email SET NOT NULL" add_column :users, :encrypted_password, :string, :limit => 128 add_column :users, :password_salt, :string, :limit => 255 require 'devise/encryptors/bcrypt' ConversionUser.find(:all).each do |u| password_salt = Devise::Encryptors::Bcrypt.salt(Devise.stretches) u.update_attributes!(:password_salt => password_salt, :encrypted_password => Devise::Encryptors::Bcrypt.digest(u.password, Devise.stretches, password_salt, Devise.pepper)) end add_column :users, :confirmation_token, :string, :limit => 255 add_column :users, :confirmed_at, :timestamp add_column :users, :confirmation_sent_at, :timestamp execute "UPDATE users SET confirmed_at = created_at, confirmation_sent_at = created_at" add_column :users, :reset_password_token, :string, :limit => 255 add_column :users, :remember_token, :string, :limit => 255 add_column :users, :remember_created_at, :timestamp add_column :users, :sign_in_count, :integer, :default => 0 add_column :users, :current_sign_in_at, :timestamp add_column :users, :last_sign_in_at, :timestamp add_column :users, :current_sign_in_ip, :string, :limit => 255 add_column :users, :last_sign_in_ip, :string, :limit => 255 add_column :users, :failed_attempts, :integer, :default => 0 add_column :users, :unlock_token, :string, :limit => 255 add_column :users, :locked_at, :timestamp remove_column :users, :password remove_column :users, :persistence_token add_index :users, :email, :unique => true add_index :users, :confirmation_token, :unique => true add_index :users, :reset_password_token, :unique => true add_index :users, :unlock_token, :unique => true 

    请注意,在这里我已经将纯密码列转换为Devise的bcryptencryption列 – 如果您已经使用Authlogicencryption密码,那么您可能需要重命名该列(如有必要),然后select正确的encryption模块在config/initializers/devise.rb

    作为参考,我的用户模型中的“devise”条款如下所示:

     devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :confirmable, :lockable, :timeoutable, :authentication_keys => [ :login ] 

    请注意,覆盖:authentication_keys以便用户login他们的login,而不是他们的电子邮件地址,需要我修改一些devise意见: rails generate devise:views ,然后编辑文件。

    希望这个对你有帮助。 祝你好运!

    sanityinc的答案是伟大的! 非常感谢!

    但是我有一个不同版本的authlogicencryption的密码,我最后的升级是:

     rename_column :users, :crypted_password, :encrypted_password add_column :users, :confirmation_token, :string, :limit => 255 add_column :users, :confirmed_at, :timestamp add_column :users, :confirmation_sent_at, :timestamp execute "UPDATE users SET confirmed_at = created_at, confirmation_sent_at = created_at" add_column :users, :reset_password_token, :string, :limit => 255 add_column :users, :remember_token, :string, :limit => 255 add_column :users, :remember_created_at, :timestamp rename_column :users, :login_count, :sign_in_count rename_column :users, :current_login_at, :current_sign_in_at rename_column :users, :last_login_at, :last_sign_in_at rename_column :users, :current_login_ip, :current_sign_in_ip rename_column :users, :last_login_ip, :last_sign_in_ip rename_column :users, :failed_login_count, :failed_attempts add_column :users, :unlock_token, :string, :limit => 255 add_column :users, :locked_at, :timestamp remove_column :users, :persistence_token remove_column :users, :perishable_token remove_column :users, :single_access_token add_index :users, :email, :unique => true add_index :users, :confirmation_token, :unique => true add_index :users, :reset_password_token, :unique => true add_index :users, :unlock_token, :unique => true 

    ..它非常适合MySQL。

    如果用户login时遇到“无效哈希”错误,请在用户模型中添加:encryptable。 我已经从authlogic迁移到devise。 我的数据库是MySQL。

    如果你得到encryption错误,请尝试在devise.rb config中更改这些错误:

     config.stretches = 20 config.encryptor = :authlogic_sha512
