Ruby on rails Rails日志。这是什么意思

我在我的开发日志上看到了这个。麦切线是什么意思？它们是SQL查询吗

[numberm

只是——它应该在智能终端上显示漂亮的颜色，否则看起来很糟糕

缓存

是“一个sql查询，缓存（以前执行，现在从缓存加载）”-例如参见

，这是Rails sql缓存工作的证据：

---

缓存意味着您已经运行了同一个查询，并且它的结果存储在内存中，因此该查询实际上不是针对数据库运行的。它们都是查询，这是Active Record在与数据库对话时实际执行的操作。

如果您使用“-r”开关查看日志，则可以使用“less”。“less-r development.log"，这将正确解释ANSI代码并使事情看起来更美好。@Roadmaster:很高兴知道，谢谢！日志的输出应该是

cat

'd或

tail-f

'd，显示在终端可以解释代码的屏幕上。如果使用编辑器，或

less

而不使用

-r

，您将获得uuuuu-gly输出。Thanks！你知道任何适用于windows的智能终端吗？嗯，可能最著名的是PuTTY——一个SSH客户端/终端模拟器：（虽然不作为本地控制台使用）。还有@rwilliams说的。谢谢你的提示。我会检查它们的。PuTTY是一个多用途工具，它也是分片和骰子的。
