web_tasks's Issues
B1
功能实现的挺好的, 但是还是有一些问题
- 为什么删除留言是一定成功的?id不存在呢?
<div>
删除成功
<form action="/" method="get">
<input type="submit" value="返回">
</form>
</div>- 查询失败没有提示, 这里应该是有提示的, 并且, 不能传入id数组查询
再说代码上的
- 有很多莫名其妙的代码
# 这两个变量好像没用?
$search_1 = Array.new #储存筛选作者后的记录数组
$search_2 = Message.new #储存筛选ID后的记录
# add路由里的这一行代码是什么意思?
@del_info = "删除成功 已删除#{$del_num}条留言"- 初始化代码写在configure(不了解的话, 看一下文档)里, 不要直接写在顶层空间.
- 一些类的定义最好提取出来放在另一个文件中, 方便管理.
params['id'].to_i, 对参数直接调用to_i方法, 如果恶意传入不是数字的参数呢?这个方法转换失败的话也不会抛出异常,而是直接返回0的.
代码风格不错, 功能也基本实现了.继续加油.
