Generate short UUIDs and use them as paths for uploaded media files in Django.
django-uuid-upload-path generates short UUIDs to use as paths for uploaded media files in Django.
- Generate short (22 character), URL-safe base64-encoded UUIDs.
- Upload media files to short UUID filenames.
- Checkout the latest django-uuid-upload-path release and copy or symlink the uuid_upload_path directory into your PYTHONPATH. If using pip, run pip install django-uuid-upload-path.
Generating short UUIDs
Generate a short, URL-safe UUID as follows:
from uuid_upload_path import uuid uuid() // -> "hCdLEjlQQJW25-sXB3T_Gw"
Generating upload paths
To upload media files to short UUID filenames, just set upload_to to uuid_upload_path.upload_to.
from uuid_upload_path import upload_to class YourModel(models.Model): file = models.FileField( upload_to = upload_to, )
Why use UUIDs as upload paths?
Django tries to ensure that all your uploaded files are given unique names on the filesystem. It does this by checking if a file with the same name exists before saving a new one, and adding a suffix if the new file would otherwise conflict with the existing one.
If you’re saving files to disk using the built-in django.core.files.storage.FileSystemStorage, this isn’t much of a problem. However, if you’re using a cloud file storage, such as storages.backends.s3boto.S3BotoStorage, this uniqueness check can have a noticeable effect on the performance of file uploads. Worse, the default configuration of S3BotoStorage is to overwrite existing files with the same name when uploading a new file!
By generating a unique filename for each uploaded file, django-uuid-upload-path removes the need for a costly uniqueness check, and avoids accidentally overwriting existing files on remote cloud storages.
