Ask HN: a "modeling" tool for Rails?

Is there something like an abstracting tool(commercial or not, ide/browser/console or whatever based) to create, manage and have a complete sight over a Rails application models,their relationships (and validation as a plus)?

I've made my research but I could not find anything all-around enough...

An alternative could be a tool to import db tables and relationship into rails models...

Any advice? Thanks.

Have you looked at Rubymine ?

I have used its model diagrams in the past to get an overview of models, and it also has class diagrams.

but the diagram part it's not interactive.. right? It's just a visualization tool I suppose? Thanks

Not aware of an interactive modelling tool. There are visualization tools like http://railroady.prestonlee.com which generates graphs showing your model layout. Don't expect too much on the cosmetic side though.
