Hey,

I’m modelling some apps with 40+ models at the moment, using bouml for  
the uml.

What I hate about modelling is that I have to write the generator  
commands for the migrations or models by hand. So I have to write the  
whole bunch at least twice, once for the modelling once for the actual  
generation.

Since tools like bouml, dia and others support a lot of format for  
exporting the uml diagrams, I wondered if there is a way to generate  
either rails migrations, rails models or the proper generator commands  
automatically.  
Alhtough some of these tools support code generation for a variety of  
languages, I haven’t found anything that I could use to generate  
something like the above.

My question now is, does anyone know a tool that can convert, either  
uml models, or interchange format into some predefined (templates)  
output?  
For example XMI into migrations using xslt or so …

greetings and thanks,  
Christoph
