GAE Graph DB creates network graphs of a Google App Engine datastore.

It depends on graphviz and pydot:

sudo apt-get install graphviz
pip install pydot

To use from the command line just supply the path to a model file and an output image file:

python gae_graph "path/to/model/file" "output.png"

To use from a Python script, first analyze the model file to get out lists of models:

edges, inheritences, nodes = analyzeModels("path/to/model/file")

Then you can write out the graph image:

writeGraph(edges, inheritences, nodes, "output.png")

Additionally, writeGraph takes two optional parameters:

• method - the graphviz program to use when creating the image
• parent_childs - a list of tuples, e.g. [('Parent', 'Child')]

Parent child relationships must be entered manually this way because they are established at run time and therefore can't be detected automatically.
