Rails 实战 0x01

1. 运用 Rails Composer自动创建项目 

rails new myapp -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb

Rails Composer是Rails App Composer的简化版本，适合新手使用，教程在这儿https://github.com/RailsApps/rails-composer/

2.  选择1）

I want to build my own application

因为1）选项可以自行设置所有配置，下面是我选择的

      3)  SMTP
      4)  SendGrid
      5)  Mandrill

      1)  None
      2)  Devise
      3)  OmniAuth

question  Devise modules? 3）Confirmable是需要邮件认证的，本地测试需配置邮件发送，当然也可以手动修改数据表或controller
      1)  Devise with default modules
      2)  Devise with Confirmable module
      3)  Devise with Confirmable and Invitable modules

      4)  Home Page, User Accounts, Admin Dashboard

extras  Add 'therubyracer' JavaScript runtime (for Linux users without node.js)? (y/n) 
extras  Set a robots.txt file to ban spiders? (y/n) n
extras  Create a project-specific rvm gemset and .rvmrc? (y/n) n
extras  Create a GitHub repository? (y/n) n

这里先不创建Github，以后手动添加BitBucket，Gitlab均可

3. 基本程序创建完成

上传到Github或其他

4. 看一下目录结构，默认第一个User是 First User，邮箱密码在application.yml中有，创建新的User我们这里因为选择了Confirmable，需要发邮件认证

5. 配置一下邮件发送，我这里用的是网易企业邮箱

Application.yml的 ADMIN_EMAIL和ADMIN_PASSWORD改成使用邮箱服务的账号密码

# 用admin_email发送确认邮件 devise.rb development.rb production.rb
ADMIN_NAME: iwissen
ADMIN_EMAIL: [email protected]
ADMIN_PASSWORD: passwd

devise.rb的config.mailer_sender改成admin_email

config.mailer_sender = ENV['ADMIN_EMAIL']

development.rb 和 production.rb 添加action_mailer的smtp_settings

  config.action_mailer.smtp_settings = {
    :address => 'smtp.ym.163.com',
    :port => 25,
    :domain => 'iwissen.com',
    :user_name => ENV['ADMIN_EMAIL'],
    :password => ENV['ADMIN_PASSWORD'],
    :authentication => :plain
  }

注意development.rb 的 config.action_mailer.perform_deliveries = true， config.action_mailer.raise_delivery_errors = true 而 production.rb 的 errors设成false

当然，使用SettingLogic gem的可以用Setting.xxx，也可以直接上字符串

这里附上Gmail的设置

config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    :address              => "smtp.gmail.com",
    :port                 => 587,
    :user_name            => 'poshboytl',
    :password             =>  ENV['GMAIL_PASS'],
    :authentication       => 'plain',
    :enable_starttls_auto => true
  }

遇到问题都可以在官方action mailer 中找到 http://guides.rubyonrails.org/action_mailer_basics.html

这样设置就完成了

6. 为了方便和符合国人习惯，把密码长度设为大于等于6（devise默认8），在devise.rb 中，修改

config.password_length = 6..128

7. rails s 开启服务器，注册新用户测试，查看console里的log

一般邮件正常发出或者根本没连的话，浏览器不会raise_error，因为设置了smtp连接，所以错误只能是连不上的错误，检查用户密码是否设置正确，邮箱域名是不是对的

8. 一切搞定后Github push一下

9. 自己创建几个一般用户和Admin用户试验一下，可见用Rails Composer还是省下了不少功夫的
