Question

I am looking for a tiny tool/script/plugin to visualize my Rails schema.rb file so that our project does not have to maintain a separate diagram manually.

Do you have any experiences on that subject?

Answer 1

Check out RailRoad.

It creates diagrams for models and controllers. I bet it will do what you want. It produces DOT files which can be viewed with Graphviz or other programs.

I’ve had some success with it, but when you have a ton of models, you may need to do some manual rearrangement to get a decent looking diagram.
