Errno 13 Allowed: folder with folder with localhost

I get a message

[Errno 13] Permission denied: u '/ home / ... / ... jpg' when I try to upload a file to django. But the problem only occurs when I try to use it with localhost /. When I run or debug it using localhost: 8000, I don't get any problems.

I create function folders when I run a script to install my database.

My code is:

def handle_uploaded_file(request,f): user=Users.objects.get(id_u=request.user.id) url=settings.MEDIA_URL+'images/'+user.mail+'/gallery/'+f.name fullurl=settings.MEDIA_ROOT+'images/'+user.mail+'/gallery/'+f.name #comprobar si existe el archivo if not os.path.exists(fullurl): destination = open(fullurl, 'wb+') ... destination.close()

Permissions in folders. I want to upload files to the "images" folder. Here I see that others do not have write permissions, but the up folder has 777. So, why does my script change permissions when creating subfolders?

 4 drwxrwxrwx 3 bernardo www-data 4096 ago 3 09:42 . 4 drwxrwxr-x 11 bernardo www-data 4096 jul 31 12:36 .. 4 drwxrwxr-x 5 bernardo bernardo 4096 ago 3 09:42 images

My http.config

 ServerName localhost WSGIPythonPath /home/bernardo/workspace/mbosoziales Alias /media/ /home/bernardo/workspace/mbosoziales/media/ Alias /static/ /home/bernardo/workspace/mbosoziales/static/ <Directory /home/bernardo/workspace/mbosoziales/static> Order deny,allow Allow from all </Directory> <Directory /home/bernardo/workspace/mbosoziales/media> Order deny,allow Allow from all </Directory> WSGIScriptAlias / /home/bernardo/workspace/mbosoziales/mbosoziales/wsgi.py <Directory /home/bernardo/workspace/mbosoziales/mbosoziales> <Files wsgi.py> Order deny,allow Allow from all </Files> </Directory>

So, I have to change permissions every time after running the first script, which makes folders for users, because they do not have write permissions in the media folder, although I believe that the rights to them are correct.

 sudo chgrp -R www-data images/ chmod -R o+w images/

Any help would be greatly appreciated. And sorry for my english :)

When you use runserver , the process runs as a regular user; and this user has access to /home/username/ to create folders and files.

When you run it under Apache, then the code runs as an apache process - usually www-data , and this user does not have access to create folders in your home directory.

The solution is not for chmod 777 , although it works. There are two best ways to approach this:

  • For use in production, change the file path to the directory where the www-data user usually has rights; and this should not be your home directory.

  • If you must use the location in your home directory; create a new path and set the parent owner to www-data:www-data . This will allow him to work without providing the protective properties of 777 .

Is it possible that the file you are creating here;

 destination = open(fullurl, 'wb+')

already created and open or used somewhere when you try to execute your code?

I think not, because I used to

 if not os.path.exists(fullurl):

therefore, opening occurs only if there is no file. I debugged it several times and it works fine, but there is a problem with permissions. At the moment, I have found a workaround that performs

 os.chmod(url,0777)

when you first start the server and create folders.
