A file storage which uses a more sane rename method for existing files.
Add DEFAULT_FILE_STORAGE = 'site.storage.BetterNameFileSystemStorage'
(obviously changing site.storage
to the module which you put this inside)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | import os
from django.core.files.storage import FileSystemStorage
class BetterNameFileSystemStorage(FileSystemStorage):
def get_available_name(self, name):
"""
Returns a filename that's free on the target storage system, and
available for new content to be written to.
"""
root, file_ext = os.path.splitext(name)
root = root.rstrip('_')
# If the filename already exists, try again with "filename_2.ext", then
# "filename_3.ext", etc.
count = 1
while self.exists(name):
count += 1
# file_ext includes the dot.
name = '%s_%s%s' % (root, count, file_ext)
return name
