django-unique-upload

A django utility that creates unique file names for uploaded files via uuids.

Why

This eliminates the need to check if the a file already exists with the same name. Checking incurs overhead. Removing the need to check boosts performance. Popular pacakges like django storages don't check if a file already exists with the same name by default. They instead overwrite the file. Using unique file names ensures that no file is over written.

Install

pip install django-unique-upload

Usage

Simply use the unique_upload function as value for a model's FileField or ImageField upload_to argument:

from __future__ import unicode_literals

from django.db import models
from django.utils.encoding import python_2_unicode_compatible
from unique_upload import unique_upload


@python_2_unicode_compatible
class MyModel(modles.Model):
    image = models.ImageField(upload_to=unique_upload)
    file = models.FileField(upload_to=unique_upload)

Now if we give save MyModel with two new files, cool-image.jpg and really-important.pdf, Django will save the files to S3 with the values: 3fce8b21-5b0d-4f27-9d99-2bb202f211c7.jpg and 50a44439-843e-4049-949d-b54cfcddff19.pdf.

Tests

Run the devepment tests with:
