Django 1.7 won't make migrations with the format_filename function because it has an included function called 'upload_to', which it returns. When running makemigrations, Django attempts to serialize a path to 'upload_to,' which doesn't actually exist, and the command fails.
Django offers this explanation:
Please note that due to Python 2 limitations, you cannot serialize
unbound method functions (e.g. a method declared and used in the
same class body). Please move the function into the main module body
to use migrations. For more information, see
https://docs.djangoproject.com/en/1.7/topics/migrations/#serializing-values
I'm not sure what to do about this.
