On my job we need save all upload files for 5 year. Losing a lot space on server with this files, because this I created this application.

# Feature only for version v9.0+
FILE_COMPRESS_QUEUE = 'Celery' # by default queue is Celery, but you can change this with this var on settings
INSTALLED_APPS = (
...
...
'compress_storage',
)
Usage
# example model.py
from django.db import models
from compress_storage import ZipFileField
class MyContent(models.Model):
name = models.CharField(max_length=150)
create_date = models.DateTimeField(auto_now=True)
upload_file = ZipFileField(upload_to='mycontent/')
def __unicode__(self):
return self.name
Shell
>>> from example.core import MyContent
>>> m = MyContent.objects.get(id=2)
>>> m.upload_file
<ZipCompressFieldFile: mycontent/test.txt>
>>> m.upload_file.compress()
>>> m.upload_file
<ZipCompressFieldFile: mycontent/test.zip>
Using with Celery
If Celery are installed on Site Packages. You just need create one post_save on your model to use async compress.
# listeners.py file
from django.db.models.signals import post_save
def auto_compress_file_on_post_save(sender, instance, **kargs):
instance.upload_file.compress()
post_save.connect(auto_compress_file_on_post_save, sender=MyContent)
If you don´t wanna use Celery async compress:
def auto_compress_file_on_post_save(sender, instance, **kargs):
instance.upload_file.compress(async=False)
post_save.connect(auto_compress_file_on_post_save, sender=MyContent)
