从 Authlogic 迁移到 Devise [英] Migrating from Authlogic to Devise

问题描述

我之前在我的网站上实施了 Authlogic 进行授权.但是现在我希望改用 Devise，我想知道是否有人对此有任何经验.也许有人看过关于这个主题的博文?

I've previously implemented Authlogic for authorization on my site. Now however I wish to switch over to using Devise instead, and I'm wondering if anyone has any experience with this. Perhaps anyone's seen a blog post on the subject?

谢谢.

推荐答案

我自己最近从 Authlogic 切换到 Devise，也没有找到任何文章.但是，在简单的情况下，一旦您丢弃了所有 user_session 和其他与 authlogic 相关的代码，主要的工作就是将旧的用户表转换为 devise 期望的格式.

I myself switched from Authlogic to Devise recently and also didn't find any articles. However, in the simple case, once you've thrown away all of your user_session and other authlogic-related code, the main piece of work is converting your old users table to the format expected by devise.

我的旧桌子是这样的:

      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)

并且我确定该表必须至少包含以下设计信息(启用了许多可选功能):

and I determined that the table would have to contain at least the following info for devise (with many optional features enabled):

 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简单的activerecord类

So I defined an unadorned activerecord class in the migration class

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

然后这是我最终使用的向上"迁移代码(使用 PostgreSQL):

and then here's the "up" migration code I ended up using (with 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，这里我已将一个普通密码列转换为用于 Devise 的 bcrypt 加密列——如果您在 Authlogic 中使用了加密密码，那么您可能只想重命名该列(如有必要)和在 config/initializers/devise.rb 中选择正确的加密模块.

Note that here I've converted a plain password column into a bcrypt-encrypted column for Devise -- if you've used encrypted passwords with Authlogic, then you'll probably want to just rename the column (if necessary) and choose the correct encryptor module in config/initializers/devise.rb.

作为参考，我的 User 模型中的devise"子句如下所示:

For reference, the "devise" clause in my User model looks like this:

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

请注意，像这样覆盖 :authentication_keys 以便用户使用他们的登录名而不是他们的电子邮件地址登录需要我修改一些设计视图:rails generate devise:views，然后编辑文件.

Note that overriding :authentication_keys like this so that users sign in with their login rather than their email address required me to modify some of the devise views: rails generate devise:views, then edit the files.

希望这会有所帮助.祝你好运！

Hope this helps a bit. Good luck!
