对大多数网站来说,访客实际使用的第一个功能就是注册&登陆,而整个注册&登陆流程的简洁流畅与否往往决定了访客的第一印象.下面结合在YMate.me开发过程中学到的些许经验,和大家探讨下.

自建帐号体系的利与弊

通常做法,自建注册表单.

好处是:

可以自定义需要的资料,不必担心第三方登陆接口缺乏必要的信息.

隐私政策是服务中非常重要的部分,它向用户传达你的"不作恶"底线在哪.鉴于大段的文字让人难以阅读,我们仅就用户最关心的数据安全做出回应:

1. **数据是用户的.**除了为您提供服务外的必要权限,您拥有所有权限.

2. **数据是受保护的.**数据默认私有,我们不会查看、分析、共享这些数据,也不会用做数据挖掘.除非您授权或您违反了相关法律法规.

3. **数据是可转移的.**您可以随时迁入迁出YMate,我们不会设置任何障碍.

我们不会主动记录您的任何密码信息,我们甚至在Web日志中专门过滤了密码.

所有的坑都来自于 无知 ,这次也不例外,我又掉坑里了...

先来看段代码:

  def change
    add_column :servers, :vip_date, :date, :default => Date.today
  end

这是一个很常见的迁移任务,新增一栏,设置默认值.执行迁移也毫无警告,看起来一切都那么美好.而真相其实是这样的:

以下简称(R3和R4),步骤比较多,做下笔记:

升级你的Gemfile

修改Gemfile中的gem 'rails', '~>4.0.0',删除assets group.

执行bundle update

如果你希望使用旧的Model安全机制,那么要记得添加protected_attributes.

升级配置文件
