However, how to make `files` field be modified automatically while
`status` field changed ?
"""
================================================================
For example, I add new record
from django.core.files import File
myfile = File(open('/tmp/old.7z'))
t.Seed(name='TCPL', category=Category(pk=1), status=UNAPPROVE)
t.files.save(name=t.name, content=myfile)
t.save()
t.status = ACCEPT
# I want t.files changed automatically here
# How to do it ?
t.save()
