Hi Tim,
Traceback is below.
As a temporary measure to get me going I have commented out the existing
migrations that added and removed the migrations. There is an initial
migration that adds the FK, a RunPython that checks for the FK to perform
some logic, and a migration to remove the FK. The RunPython does not import
the model that has the FK. It uses the apps.get_model() method. I have also
added the function called by RunPython below, in case that is of any use.
Thanks,
Dylan
