Hey.
I needed a fix to make some (but not all) models in an existing app
delete the previous content of a FileField after update. I figured
out a workaround, but should I be wary of anything with this
implementation, or is there a better way to do it?
Thanks.

from djano.contrib.contenttypes.models import Model
class OrderedModel(Model):
dev save(self):
# Some custom save code to facilitate ordering
class FileReplacerMixin():
def save(self):
# Code to check each FileField for changes and delete as
appropriate.
# Now I can have Ordered or Unordered models which
# either replace files or keep the previous content around, such as:
class OrderedModelWhichReplacesFiles(OrderedModel, FileReplacerMixin):
def save(self):
# Call the mix-in to replace files
FileReplacerMixin(self)
# Call the parent class's save function
super (OrderedModelWhichReplacesFiles, self).save()
