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_alldoesn't raise during app boot
