#const_source_location(class_name) ⇒ Object

Unfortunately this bug (github.com/ruby/ruby/pull/5646) prevents us from using Ruby’s native Module.const_source_location. Instead we have to fudge it by searching for the file in the configured autoload paths. Doing so relies on Rails’ autoloading conventions, so it should work ok. Zeitwerk also has this information but lacks a public API to map constants to source files.

  # NOTE: underscore respects namespacing, i.e. will convert Foo::Bar to foo/bar.
  class_path = "#{class_name.underscore}.rb"

  ActiveSupport::Dependencies.autoload_paths.each do |autoload_path|
    absolute_path = File.join(autoload_path, class_path)
    return absolute_path if File.exist?(absolute_path)
