在 Rails 项目中找不到原点对象 [英] Cannot find origin object in Rails project

问题描述

我刚刚为一个新的演出继承了一个 Rails 应用程序.你的代码很疯狂，并且深深地埋在了 gem 逻辑中，所以导航非常困难，而且不符合轨道.我很难追踪以下逻辑.

I just inherited a Rails app for a new gig. Thee code is insane and heavily buried in gem logic so VERY difficult and un-rails-like to navigate. I am having a terrible time tracking down the following logic.

    @navigator ||= BitPlayer::Navigator.new(current_participant)

我到处(在应用程序和 gem 目录中)搜索 BitPlayer 类/对象以及导航器，但找不到任何东西.我想我不明白这条线的基本组成.

I have searched everywhere (in app as well as gem dirs) for a BitPlayer class/object as well as Navigator and cannot find a thing. I am thinking I don't understand the fundamental composition of the line.

有人能指出我在哪里寻找这个的正确方向吗?我迫切需要找到那个Navigator.new".方法！

Can someone point me in the right direction where to look for this? I desperately need to find that "Navigator.new" method!

推荐答案

你可以试试 Method#source_location.例如:

You could try Method#source_location. For example:

Nokogiri::HTML.method(:fragment).source_location
# ["/Users/mu/.../gems/nokogiri-1.10.10/lib/nokogiri/html.rb", 29] 

然后查看我们看到的文件的第 29 行:

And then looking line 29 of the file we see:

def fragment string, encoding = nil

所以开始:

BitPlayer::Navigator.method(:initialize).source_location
