=================================

 

1:Encryptable:除了内置的Bcrypt(默认),增加支持认证机制

 

2:Lockable:锁定一定数量的失败尝试登录。通过电子邮件或之后才能解锁

 

3:validatable:有效性:提供的电子邮件及密码鉴定。它是可选的,可定制的,所以你可以定义自己的代码。

 

4:Timeoutable:在一特定时期(expires sessions)没有活动。

 

5:Trackable(跟踪):追踪 登录的次数、时间戳记签字和IP地址

 

6:Rememberable(记忆):管理产生和清除表示来自用户保存的cookie的标记(token)

 

7:Registerable(注册):处理用户注册过程,也可以让他们编辑和摧毁他们的帐户。

 

8:recoverable(重设)重置用户密码并且发送重置指令。

 

9:Confirmable注册登录认证

 

10:Omniauthable: adds Omniauth (github.com/intridea/omniauth) support;

 

11:Database Authenticatable: encrypts and stores a password in the database to validate the authenticity of a user while signing in. The authentication can be done both through POST requests or HTTP Basic Authentication.

 

12:Token Authenticatable: signs in a user based on an authentication token (also known as “single access token”). The token can be given both through query string or HTTP Basic Authentication.

 

 

 

通过Divse 添加Users

 

其中User.rb可用属性:12个

 

    :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable  , :omniauthable ,

 

    :database_authenticatable, :registerable,  :recoverable, :rememberable, :trackable, :validatable,

 

使用:

 

1:Gemfile中加入: gem 'devise'

 

2:建立devise档案: rails g devise:install(自动在routes.rb中加入:devise_for:user)

 

3:预设定网站网址:在config/environmentents/development.rb与production.rb中加入

 

    config.action_mailer.default_url_options = { :host => 'localhost:3000' }

 

4:在app/views/layouts/application.html.erb layout中加入:(提示flash信息)

 

    <p class="notice"><%= notice %></p>

 

     <p class="alert"><%= alert %></p>

 

5:设定主页,在routes.rb中

 

    root :to => ""

 

6:产生User model以及Migration

 

    rails  g devise user

 

7:如果需要E-mail验证登录功能,修改user.rb migration将confirmable打开

 

8:产生view模板

 

    rails g devise:views

 

9:建立资料表

 

    rake db:migration

 

使用:

 

在需要登录的control中加上:before_filter:authenticate_user!

 

!!

 

定制登录信息:(注意修改:)

 

    devise默认是email和密码登录,那么,现在用用户名登录!配置如下:

 

1:添加username字段到User表单

 

    rails generate migration add_username_to_users username:string 

 

     rake db:migration

 

2:修改配置文件:是devise默认用username登录/config/initializers/devise.rb

 

    config.authentication_keys = [ :username ]

 

    config.sign_out_via = :get

 

3:修改注册页面,app\views\devise\registrations\new.html.erb(类似修改其他devise的视图)

 

        <h2>Sign up</h2>

 

    <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>

 

      <%= devise_error_messages! %>

 

      <p><%= f.label :username %><br />//////

 

      <%= f.text_field :username %></p>//////

 

      <p><%= f.label :email %><br />

 

      <%= f.email_field :email %></p>

 

      <p><%= f.label :password %><br />

 

      <%= f.password_field :password %></p>

 

      <p><%= f.label :password_confirmation %><br />

 

      <%= f.password_field :password_confirmation %></p>

 

      <p><%= f.submit "Sign up" %></p>

 

    <% end %>

 

    <%= render :partial => "devise/shared/links" %>

 

4:重启服务-效果成功
