Software Engineer working since 2008 with Ruby / Ruby on Rails, love a bit of Elixir / Phoenix. I also poke through other people's code and make PRs for OpenSource Ruby projects that sometimes make it. Currently working at making code out of bricks.

Logging Unpermitted Parameters

Found out Unpermitted Parameters has instrumentation. So we can hijack it


logger ='log', 'unpermitted.log'))
ActiveSupport::Notifications.subscribe 'unpermitted_parameters.action_controller' do |name, start, finish, id, payload|
  msg = "Unpermitted_parameters: #{payload[:keys].map { |k| ":#{k}" }.join(', ')}"
  puts Rainbow(msg).red.underline

And now I have STDOUT and logs full of debug with no context whatsoever but hey, thats’s in Rails 7

Robs-MacBook-Pro:sard rl$ tail -f log/unpermitted.log
