请问各位这段时间 Googlebot 能正确访问你们的网站吗？

moioo — Sat, 05 Jul 2014 21:07:56 +0800

这几天总是收到

在过去 24 小时内，Googlebot 在尝试访问您的 robots.txt 时遇到了 21 个错误。为确保不会抓取该文件中列出的任何网页，我们推迟了抓取操作。您网站的 robots.txt 总体错误率为 100.0%

主机用的是阿里云。dns 之前用的 dnspod 服务，现在改用阿里云智能 DNS 还是一样，不知大家没有同样的问题。

capybara fill_in 在 Firefox 29.1 的问题

moioo — Sat, 10 May 2014 19:56:35 +0800

今天升级 firefox 写代码再 rspec 结果测试不通过找了很久原因，发现是升级 firefox 造成的升级 firefox 到 29.1 后，fill_in 对不对正常填充，其它类型正常。降级 28.0 后能正常。又试了 chrome 发现存在同样的问题。有那位小伙伴也遇到同样的问题？

Selenium 测试问题

rspec 功能测试下定单成功后进入打印页，现无法获取打印窗口并取消这个窗口我只知道确认对话框取消

alert = page.driver.browser.switch_to.alert
alert.cancel

这个打印窗口 google 一下，没找到方法

rails4.1 发布了，手痒升到 4.1 再 rspec 报错，折腾 1 个多小时没找到原因 student.rb

before_create do |t|
  t.rno = t.generate_rno
  t.pinyin_name = Pinyin.t(t.name,:splitter => '')
end

before_update do |t|
  t.pinyin_name = Pinyin.t(t.name,:splitter => '') if t.name_changed?
end

以上在 4.0.4 执行正常无报错 rails 4.1

在 4.1 却执行报错，看了一下执行 sql 发现都执行了两次非常困惑
