Rails 6.1 - Zeitwerk warnings for Clearance and Omniauth
Everytime my Sidekiq process started, I was met with these errors:
WARN: DEPRECATION WARNING: Initialization autoloaded the constants ConfirmedUserGuard, ApplicationHelper, EmailHelper, ApplicationController, and OauthController. Being able to do this is deprecated. Autoloading during initialization is going to be an error condition in future versions of Rails. Reloading does not reboot the application, and therefore code executed during initialization does not run again. So, if you reload ConfirmedUserGuard, for example, the expected changes won't be reflected in that stale Class object. These autoloaded constants have been unloaded. In order to autoload safely at boot time, please wrap your code in a reloader callback this way: Rails.application.reloader.to_prepare do # Autoload classes and modules needed at boot time here. end That block runs when the application boots, and every time there is a reload. For historical reasons, it may run twice, so it has to be idempotent. Check the "Autoloading and Reloading Constants" guide to learn more about how Rails autoloads and reloads.
