Since its release in 2004, Ruby on Rails has evolved into a widely used full stack model-view-controller (MVC) framework. But despite the fact, that Rails (short for Ruby on Rails) is also used for developing enterprise-scale applications like Github or scientific tools like QTREDS, there is no official support for graphical modelling. This paper introduces a proposal to fill this gap by suggesting a model driven approach using the free yEd diagram editor as well as a specifically developed transformation tool and ER dialect. The implementation is based on the Rails data abstraction layer ActiveRecord and its provided domain specific languages.
