使用 ruby-debug 对我来说似乎是一个陡峭的学习曲线,任何人都可以指向类似于logger.debug的东西,也许?

好的,我想我已经开始了解ruby-debug。
一些有用的新手注意事项设置&使用ruby-debug:
lockquote
gem install ruby-debug $ b $ config / environments / development.rb添加
include'ruby-debug'
然后在要调试的代码上面添加:
调试器
如果您需要调试第三方插件/ gem,使用
包括'ruby-debug'
调试器
只需使用ruby脚本/服务器运行,不需要添加--debugger

这个插件真的帮助我理解Rails应用程序的流程。我强烈建议这对任何新手都要亲!
只需设置ruby-debug,然后在您的应用程序请求的操作下将调试器代码放在控制器中的任何位置。你会发现很好的启示!
我强烈建议你学会使用 ruby-debug 。您可以通过执行以下操作来安装它:
gem install ruby-debug
然后,您可以在插件代码或您的代码调用插件的位置向代码中添加调试器
语句,看看发生了什么问题。
我也亲自使用这些设置,使它更容易使用 - 将它们放在〜/ .rdebugrc
文件。
set autoeval
set autolist
设置自动加载
Is there a way like how we debug models / controllers with logger.debug? Or even a better method?
Thank you!

Using ruby-debug seems like a steep learning curve for me, could anyone point me something similar to logger.debug, perhaps?

Alright, I think I started to get a grasp on ruby-debug.
Some useful notes for newbies to setup & use ruby-debug:
gem install ruby-debug in config/environments/development.rb add
include 'ruby-debug'
then just above the code you want to debug add: debugger if you need to debug third party plugin / gem, use include 'ruby-debug' debugger just use ruby script/server to run, no need to add --debugger

This plugin really helps me out in understanding the flow of Rails application. I highly recommend this to any newbies going pro!
Simply setup ruby-debug, then put debugger code anywhere in your controller under the action your application requested. You will then find great revelation!
I highly recommend you learn to use ruby-debug. You can install it by doing:
gem install ruby-debug
You can then add a debugger
statement to your code either in the plugin code or where your code calls the plugin, step through it, and see what's going wrong.
I also personally use these settings which makes it a bit easier to use - put them in a ~/.rdebugrc
file.
set autoeval
set autolist
set autoreload
