Cannot find origin object in Rails project

问题

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)

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.

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

回答1:

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] 

And then looking line 29 of the file we see:

def fragment string, encoding = nil

So start with:

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