cancan 也是个不错的 gem 包,很多人用它管理权限。
美女又走了
@zhuf 不去去?
报名。
是不是爬的太勤了,人家服务器扛不住阿。
三方协议没什么用处
我的英文还可以。但是我不建议直接上英文原版。
新手不熟悉基本概念,会浪费很多时间揣测原文的意义。不如先看一些中文材料,了解这个领域需要的基本概念,比如 路由/MVC 等等。然后再深入的阅读原著。
能有事半功倍的效果。
这是我的个人愚见。
感谢两位的回复。刚刚读了这篇文档. http://rubymonk.com/learning/books/1/chapters/35-modules/lessons/80-modules-as-namespaces
图片中的两个冒号应该是 namespace, 不是引用常量吧。
不仅仅是书籍,论文的出版现在也被牢牢的控制着。
上面一段代码是 RailsCast 中的一个 builder, 生成 feed 专用。
网址: http://railscasts.com/episodes/87-generating-rss-feeds-revised?view=asciicast
代码是不是有问题啊?我怎么感觉应该写成下面这种格式?
atom_feed do |feed|
feed.title "Superhero Articles"
feed.updated @articles.maximum(:updated_at)
@articles.each do |article|
feed.entry do |entry|
entry.published article.publisherd_at
entry.title article.name
entry.content article.content
entry.author do |author|
author.name article.author
end
end
end
end
已经收到邮件了。
非常感谢。
顶起。
明天还有其他活动,唉。
6+ year,
都公司中层了。
两种数据格式不同,model 暂时还不会写。
求合影照片
没有十全十美的活动,daniel 不要压力太大。
辛苦了。
我去扯蛋。哈哈。
今天忽然发现还有另外一种论文结构,冏。 请问一个 model 下,可以有不同的文档结构(schema)吗?
