What is the officially supported way to customize the topic RSS output by replacing the default show.rss.erb template?

after_initialize do
  class ::TopicsController
    prepend_view_path File.expand_path("../app/views", __dir__)
  end
end

• I think you should use __FILE__ instead of __dir__
• If you’re calling it outside of a class body it should be self.prepend_view_path

So I believe this will work

after_initialize do
  class ::TopicsController
    self.prepend_view_path File.expand_path("../app/views", __FILE__)
  end
end
