如何在Ruby on Rails中为耙任务使用自定义日志? [英] How do I use a custom log for my rake tasks in Ruby on Rails?

问题描述

我有一个rake任务，调用以下函数:

I have a rake task that calls functions like this:

namespace :blah do
    task :hello_world => :environment do
       logger.info("Hello World")
       helloworld2
    end
end

def helloworld2
   logger.info("Hello Again, World")
end

我希望将日志输出到自定义日志，并且我真的不想每次进行函数调用时都必须传递日志引用.我在某个地方找到了它(无法再次找到它):

I want the log output to a custom log, and I really don't want to have to pass a log reference every time I make a function call. I found this somewhere (can't find it again):

def logger
  @@logger ||= Logger.new("#{RAILS_HOME}/log/blah.log")
end

但这对我不起作用，我不确定它能做什么，因为我很久以前就抓取了代码，直到现在才使用它.我无法在Google上搜索@@(尝试+"@@"导轨)来查看其功能.在这个问题上的任何帮助将是巨大的.我希望有一个快速的解决方案，而不必安装gem或插件(除非有确实非常好的理由.

But this does not work for me and I am not sure what it even does because I grabbed the code a long time ago and haven't used it until now. I can't search for @@ on google (tried +"@@" rails) to see what it does. Any help on this issue would be great. I am hoping for a quick solution and not having to install a gem or plugin (unless there is a really really good reason to.

谢谢！

推荐答案

rake禁用生产模式下的日志记录.如果要记录日志，请确保您正在开发模式下运行

rake disables logging in production mode. make sure you're running in development mode if you want it to log
