OSError on uploading files in Django

While trying to send form with image field in it I'm getting :

Exception Type: OSError at /user/register/

Exception Value: (13, 'Permission denied')

Of course first thing I've checked were the permissions to my folders, and just in case set them to 777 on the whole path from '/'. Still nothing. So I've tried adding parameters to settings, which now are set like this :

And finally my traceback :

Any ideas what more should I check ?

UPDATE : My model

class UserProfile(InheritedProfile):
    def upload_path(self, field_attname):
        filename = hashlib.md5(field_attname).hexdigest()[:4] + "_" + field_attname
        return "uploads/users/%s" % (filename,)

    user = models.ForeignKey(User, unique=True, related_name='profile')
    image = models.ImageField(upload_to=upload_path, verbose_name="Image", blank=True, null=True)

I have already created 'uploads/users' folder so why is it trying to create a folder - not just a file ?

The apache use that runs your django application does not have the permission to create the folder/file in your media directory.

A quick temporary fix would be to

Go to your media folder:

/home/fandrive/www/fandrive/site_media

and type:

sudo chmod -R a+w

which makes your folder writeable by all users.

This approach may not be secure. To make it secure, you can change the ownership of the folder to that user, or create a group and assign the permissions to that group.
