Postgresql has referential integrety checking.

Postgresql has referential integrety checking.

So some of my dangling foreign keys caused tests to failed.
I resolved them through a few different ways,
  * adding initial_data to include description tables
  * adding some additional data to the test fixture.
  * renumbering affiliation keys to match my small test list.

I had to reorder the app list because I think there was a dependency
in the wrong order.
