Diary of a Mad Rails Engineer
summary
Claim: Rails::Engine is not just a concept but a packaged gem that actually contains models, controllers and views and can be mounted into an app. Using Rails 3 era engines and mountable/isolated mode this workflow produces working outcomes: a published gem around 3.0 that became one of the earliest engines, an entity_relation_diagram engine that mounts and draws models and saves layout, a REST diagram generator and a browser action recorder that all prove mounted engine loads parent app models and isolated mountable engines avoid namespace conflicts.
