This is a dependency checking / generating tool that highlights dependencies between apps.
One type of dependency is that models from app A have a reference to a model in app B.
Another one is simply where code is called.
The tool is a Django management command that can simply be called by
./manage.py dependency_tree
especially
./manage.py dependency_tree --help
might be helpful.
The final output is a graphviz file between the "-----------" lines
Just copy it into an empty file and run the graphviz (https://graphviz.org/) compiler, e.g. with dot dependencies.dot -Tpdf -o test.pdf to generate a PDF.
Example commands are:
./manage.py dependency_tree --contains-app=test --with-labels
to show all relations of the "test" app (from / to) and add the name of the models, functions or classes as labels.
Or:
./manage.py dependency_tree --from-app=example --with-labels
to show which apps the "example" app calls code from.
To get the full picture of all relations, just call:
./manage.py dependency_tree --with-labels
BUT beware... you might not like what you see :)
