Django - Media upload [Errno 13] Permission denied

Question

I'm having some trouble getting django to play nice with image uploads. My script will create directories based on the date like so:

file = models.FileField(upload_to='uploads/%m-%Y/')

Now, if I create the dated directory in the uploads folder and chmod the folder to 755, the upload works fine, but if I try to chmod the uploads folder without creating the dated sub folder (which I need django to do), I am getting a permissions error.

How do I make it so a folder will allow the creation of sub folders?

Here is a traceback:

Solution 1

The process that is running your Python interpreter doesn't have permission to write into the media directory. You'll need to either chgrp or chown the media directory to the same group as your Python process, and ensure you have at least g+rwx on directories and g+rw on files.

Solution 2

I was getting the same error and fix it by changing:

MEDIA_ROOT = '/media/'

to:

MEDIA_ROOT = 'media/'

Under settings.py.

Solution 3

For me, I forgot to add: MEDIA_ROOT = os.path.join(BASE_DIR,'media') to my settings.py file on my production server.

Sorry, could you tell me what command I would use to find out the permissions on a folder? I am using ubuntu.

And how can you tell which group the Python process is on? Thanks!

If you are running nginx, usually it's www-data. So chown www-data:www-data -R mediacommand would work. It seems you are missing -R(recursive) option when giving permission.
