进入项目

1、添加gem
    gem 'devise'

2、更新本地gem
    bundle install
3、创建页面
    rails g controller home index
4、初始化devise
    rails g devise:install
会有如下提示:
  1. Setup default url options for your specific environment. Here is an
     example of development environment:

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

     This is a required Rails configuration. In production it must be the
     actual host of your application

  2. Ensure you have defined root_url to *something* in your config/routes.rb.
     For example:

       root :to => "home#index"

  3. Ensure you have flash messages in app/views/layouts/application.html.erb.
     For example:

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

  4. If you are deploying Rails 3.1 on Heroku, you may want to set:

       config.assets.initialize_on_precompile = false

     On config/application.rb forcing your application to not access the DB
     or load models when precompiling your assets.

进行相关配置
5、与模型User关联
    rails g devise User
这条命令会生成一个user.rb model文件,一个migration文件和一个devise_for的路由
我们可以看到User model和普通的ActiveRecord的区别并不大,主要的差别是调用了devise方法,当然这也是配置的关键。Devise方法有很多的参数用来标识是否使用对应的功能模块


6.执行迁移任务
rake db:migrate
查看在router.rb文件中的devise_for都产生了什么路由.可以通过rake routes查看

产生了如下路由:登录,登出,重置密码,注册,和修改。如果我们需要,所有这些路由都是可以配置的

7、修改默认访问url
    打开routes.rb,加入:root :to => "home#index"

8、修改index.html.erb代码
<% if user_signed_in? -%> <!-- Provided by devise -->
    <div style="float:right">
      <%= current_user.email %> |
      <%= link_to '用户信息', edit_user_registration_path %> |
      <%= link_to '退出登录', destroy_user_session_path, :method => :delete %> |
    </div>
    <% end -%>
    <% unless user_signed_in? -%>
    <div style="float:right">
      <%= link_to '注册', new_user_registration_path %> |
      <%= link_to '登录', new_user_session_path %>
    </div>
<% end -%>
9、启动服务
    rails s
10、测试
    localhost:3000/home/index
