Ensure models have valid graph slug #7
Description
Credit to @jakeadolezal for finding this bug and posting about it on the forums.
On the instructions page, it says to load the sample package.
python manage.py packages -o load_package -s https://github.com/archesproject/arches-example-pkg/archive/master.zip -db
When I did, it threw a number of these exceptions, e.g.:arches.app.models.graph.GraphValidationError: 'You must supply a slug for your graph.'
/Users/jake/arches/durant/_pkg_250907_180001/arches-example-pkg-master/graphs/branches/Title.json
It looks like this package fails with Arches v8+ as none of the models have a ( now required ) slug.
