Sometimes you need generate a database diagram for your Django project. django-extensions does this well, but drops non-editable file such as PNG. Even when you use SVG format you'll waste much time with bunch of objects that are not stitched together: when you move a table, you'll need to move all connected arrows and captions.

There was a time when you could generate .dia file directly with django-extensions. But dia support was dropped.

pip install django-dia

Add django-dia to your INSTALLED_APPS:

INSTALLED_APPS = (
    #...
    'django-dia',
)

And run

./manage.py make_diagram -a -e -o scheme
./manage.py make_diagram -e -o scheme my_app1 my_app2

This will produce file scheme.dia in your project directory.
