• 非常感谢楼上所有人的帮助和指导。我会加紧学习的.感谢你们抽出宝贵的时间。谢谢!

  • #27 楼 @springwq 好的我升级一下版本。有点郁闷.版本影响这么大。非常感谢指导

  • #24 楼 @springwq 尴尬了..改了 users_helper 后确实顺利跑起来了. 我开始学习时候是想着基础太薄弱,习题先空着,照着教程先做第一遍,有个印象,利于第二遍再细致的学习通篇教程,顺带做所有习题。问题竟然是出在这里. 按照你所说我报错信息没有给全,比较奇怪的是,为什么我的机器上显示不出来呢? argumenterror 这一段我的机器上完全没有显示呢,好奇怪啊

  • #11 楼 @chenge 抱歉,基础太差了。满脑子雾水.很感谢你的耐心和提醒,我把 Log 删掉了. 我观察了一下 development.rb.你叫我修改的地方其实正是打开的。我补充一些环境和配置的基础吧. 谢谢,确实麻烦了,太新手见笑了

  • #4 楼 @chenge 呃?能具体一点吗。我不是很懂,要怎样改正呢?

  • #1 楼 @michael0015 是 Log 中的信息吗?
