Django - Media upload [Errno 13] Permission denied - django

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?

Answer 1

I was getting the same error and fix it by changing:
MEDIA_ROOT = '/media/'
to:
MEDIA_ROOT = 'media/'
Under settings.py.

Answer 2

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.

Answer 3

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

Answer 4

Make sure you have done following
Your settings.py
...
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
...
Also set permission to media directory
chgrp -R www-data /path/to/media/
chmod -R g+w /path/to/media/

Answer 5

Thanks to https://stackoverflow.com/users/10949995/clement-tong for the inspiration. I experienced the same error in a production environment and I had to change settings.py file to include a preceding forward slash:
MEDIA_ROOT = os.path.join(BASE_DIR, "/media")

Answer 6

I was getting the same error and fix it by doing the following in setting.py file of the project:
MEDIA_ROOT = '/media/'
to
MEDIA_ROOT = 'media/'
