Some additional features were added to a django application, and as a result the upload_to function also expanded.
Since django by default stores filenames in the database, and files on disk, no harm has been done - new files are named using a new upload_to function, while old files continue to work.
However, this is messy - we end up in a situation with files like
/media/userID/oldfilename.pdf
and
/media/app/userID/projectID/newfilename.pdf
Is there a way to bulk rename those files? I guess it could be done by iterating through the database, checking if the path in FileField matches the result of current upload_to, and if not, rename.. it seems like a common problem, so perhaps there is a more generic way out there?
The simple solution is to write a custom Django management command. You can run the command using Django's standard manage.py.
Something like this:
from django.core.management.base import BaseCommand, CommandError
from example.models import YourModel
class Command(BaseCommand):
args = ''
help = ''
def handle(self, *args, **options):
# Get all objects
objects = YourModel.objects.all()
for object in objects: # For each object
# If old file path:
if not 'userID/projectID' in objects.filefield.name:
# Move the file, eg usign shutil http://docs.python.org/library/shutil.html#shutil.move
# Update filefield
# save object
