django project on amazon ami nginx static

I'm running my django project on amazon AMI machine and have problem with nginx serving static files. Project static folder path is /home/user/projectname/app/static and nginx.conf is

    server {
    listen       80;

    location /static {
        alias /home/user/projectname/app/static;
    }

    location / {
        proxy_pass http://localhost:8000;
    }

I tried to make collectstatic and change static location to alias /home/user/static; but it didn't help. What am i doing wrong?
