从Restful身份验证迁移到Devise

Question

许多Rails 2.3应用程序正在使用Restful Authentication,但该插件似乎与Rails 3有一些问题.在升级到Rails 3时,我一直在使用Devise.有没有办法从Restful Authentication顺利过渡到Devise？有没有人做过迁移,显示如何更新用户模型？

Answer 1

这是从restful_authentication到devise的迁移的一个很好的指南

我已将我的应用程序从Restful Authentication更新为Devise.这是我的迁移:

class AlterUsersForDevise < ActiveRecord::Migration
  def self.up
    remove_column :users, :name
    change_column :users, :email, :string, :default => "", :null => false, :limit => 128
    rename_column :users, :crypted_password, :encrypted_password
    change_column :users, :encrypted_password, :string, :limit => 128, :default => "", :null => false
    rename_column :users, :salt, :password_salt
    change_column :users, :password_salt, :string, :default => "", :null => false, :limit => 255
    add_column :users, :reset_password_token, :string
    change_column :users, :remember_token, :string, :limit => 255
    rename_column :users, :remember_token_expires_at, :remember_created_at

    add_column :users, :sign_in_count, :integer, :default => 0
    add_column :users, :current_sign_in_at, :datetime
    add_column :users, :last_sign_in_at, :datetime
    add_column :users, :current_sign_in_ip, :string
    add_column :users, :last_sign_in_ip, :string

    rename_column :users, :activation_code, :confirmation_token
    change_column :users, :confirmation_token, :string, :limit => 255
    rename_column :users, :activated_at, :confirmed_at

    add_column :users, :confirmation_sent_at, :datetime
  end

  def self.down
    add_column :users, :name, :string, :limit => 100, :default => ""
    rename_column :users, :encrypted_password, :crypted_password
    change_column :users, :crypted_password, :string, :limit => 40
    rename_column :users, :password_salt, :salt
    change_column :users, :salt, :string, :limit => 40
    remove_column :users, :reset_password_token
    change_column :users, :remember_token, :string, :limit => 40
    rename_column :users, :remember_created_at, :remember_token_expires_at

    remove_column :users, :sign_in_count
    remove_column :users, :current_sign_in_at
    remove_column :users, :last_sign_in_at
    remove_column :users, :current_sign_in_ip
    remove_column :users, :last_sign_in_ip

    rename_column :users, :confirmation_token, :activation_code
    change_column :users, :confirmation_token, :string, :limit => 40
    rename_column :users, :confirmed_at, :activated_at

    remove_column :users, :confirmation_sent_at
  end
end

到目前为止我的申请还没有上线.所以我使用Devise的密码加密而不是Restful Authorization的加密.如果您的应用程序已处于活动状态,并且您有活动用户,则应配置Devise以使用Restful Authentication中的SHA1来解密和解密密码.否则,您的所有用户都必须申请新密码.

您可以在设计初始化程序中进行配置.

希望有帮助......

以下是如何克服密码问题:

您需要像这样制作自定义加密器:

# /config/initializers/devise_encryptor.rb
require "digest/sha1"  

module Devise
  module Encryptors
    class OldRestfulAuthentication < Base
      def self.digest(password, stretches, salt, pepper)
        Digest::SHA1.hexdigest("--#{salt}--#{password}--")
      end
    end
  end
end

然后选择它devise.rb:

config.encryptor = :old_restful_authentication

应该这样做!
