Hey,

I’m looking for a tool which allows me to visualize the data model of  
a rails application in uml diagrams. In the moment, I manually  
synchronize my uml diagrams and the ror models manually, but this  
takes too much time.

Thanks for any suggestions!

I found that schemaSpy was really helpful in visualizing and sharing  
any database’s ER diagram…
