I think @Kircheneer will need to chime in here.

[jdrew82]

@Kircheneer I've rebased @mattmiller87 's branch on next so it has all the changes that have been made in develop. I'm now getting multiple tests failing with the same error about object has no attribute '_meta' and I can't figure out how to resolve. It seems like something related to the Django Model class?

[jdrew82]

@Kircheneer with @mattmiller87's correction and I've fixed the two Infoblox tests that were failing we're just down to two contrib tests. I'm not understanding what's wrong with the tests in question so can you look to see if you can fix the issue?
