Ruby: console.log?
提问by BrainLikeADullPencil
I recently put console.log statements in every line of a JavaScript program and found that it's now much easier to understand. Is there a way to do that with server side code, specifically Ruby? I presume there's no way to read it in firebug, but would it be visible in irb? what console.log equivalent statements would I put in the Ruby code?
我最近将 console.log 语句放在 JavaScript 程序的每一行中，发现现在更容易理解了。有没有办法用服务器端代码来做到这一点，特别是 Ruby？我认为没有办法在萤火虫中读取它，但它会在 irb 中可见吗？我将在 Ruby 代码中放入哪些 console.log 等效语句？

putsis the equivalent in ruby.
puts在 ruby 中是等价的。

If you are running your server in the console, you can use puts. Otherwise, you will need to write to a file, possibly via a logger (like Rails.logger.info).
如果您在控制台中运行服务器，则可以使用puts. 否则，您将需要写入文件，可能是通过记录器（如Rails.logger.info）。
