Zeitwerk Notes

Common issues and fixes:

  • Ensure module and directory names follow constant naming (MyEngine::Admin => my_engine/admin.rb)
  • Avoid autoloading top-level constants in engine initializers; prefer lazy loading inside config.to_prepare
  • If using legacy autoloading, prefer adding explicit requires in engine's lib/.rb
  • For Rails < 6.0, document incompatibilities and recommend upgrading or namespacing as fallback

Practical checks:

  • Run bin/rails runner "puts Object.const_defined?('MyEngine')" in dummy app
  • Confirm Zeitwerk::Loader.eager_load_all doesn't raise during app boot
