Circular import with get_user_model

[b-jam]

Its fine to import, but if you import a model from this app from within your own models.py file, it will cause a circular error due to the get_user_model() running from within the code. see

for a very relevant case and how they solved.

The Django documentation has the answer: https://docs.djangoproject.com/en/dev/topics/auth/customizing/#django.contrib.auth.get_user_model

The most relevant section: Generally speaking, you should reference the User model with the AUTH_USER_MODEL setting in code that is executed at import time. get_user_model() only works once Django has imported all models.

The problem is models.py::formlog::created_by field. This field is not inside any method. So if you import this from your own models it will crash. a fix would be to put this inside a method or change it to use the AUTH_USER_MODEL setting.
