One thing you can do is use a gem like byebug, put a breakpoint above the code you want to find it's location and use this:
method(:name_of_method).source_location if you put a breakpoint inside your routes.rb and call: method(:get).source_location it returns something like: ...../gems/actionpack-6.0.2.2/lib/action_dispatch/routing/mapper.rb, 711 Than you can check the source on github https://github.com/rails/rails/blob/v6.0.2.2/actionpack/lib/action_dispatch/routing/mapper.rb#L711 It doesn't always work, you can have methods generated on the fly using define_method for example I'm not sure source_location gives you the right source there.
