Converting Django models into Graphviz DOT files

Inspired by ​this nice hack by Matt Biddulph, this is a Python script that generates a Graphviz DOT file for quick visualizations of Django model definitions.

Source code

​View online or ​download from Subversion repository (you could also set it as a svn:external on your repository to keep up to date with the latest revisons.)

Examples

​MC Minerali Ceramici

Command

Once you use this python script to generate the dot file (app.dot), ensure you have dot installed (part of Graphviz), and issue:

dot app.dot -Tpng -o app.png

Other References
