5.2这个包的时候, 怎么改变用户的角色呢?
比如:有一个用户Jim,他现在的角色是vip,30天后到期,到期后自动变为普通用户,怎么做呢?
3张表如下:
users
<code>id name email password 1 Jim Jim@example.com ****** </code>
roles
<code>id name 1 vip 2 ordinary </code>
role_user
<code>user_id role_id 1 1 </code>

role_user

你可能思路错了,一个可能的方案如下:
所有用户都拥有ordinary角色
vip用户同时拥有ordinary和vip角色
在验证vip用户权限的时候,先验证是否是vip用户,如果是,再验证账户是否到期(可以通过在roles表中设置一个expire字段,存储到期日期,如果是ordinary则默认为null,如果是vip,则设置相应的日期)
所以,不存在自动改变用户角色的问题,也就是说,vip用户在到期后,还是vip用户,只不过vip“身份”到期了,需要vip权限的资源也就不可用(通过验证expire字段)
