-8.1 Troubleshooting Database access
+
+8.1 Configure serving of static media (including page templates)
+------------------------------------------------------------------
+
+Locate the admin media files of your local django installation:
+
+    sudo updatedb
+    locate base_site.html
+
+Should bring up a folder like this:
+
+    /usr/share/pyshared/django/contrib/admin/...
+
+The media folder within contains static page elements needed for the django admin application. We can use apache to serve these files directly. First link this folder into /var/www:
+
+    sudo ln -s /usr/share/pyshared/django/contrib/admin/media /var/www
+
+Edit /etc/apache2/sites-available/default:
+
+    Alias /media/ /var/www/media/
+
+    WSGIScriptAlias / /home/django/py/labhamsterproject/config/django.wsgi
+    
+	   Order deny,allow
+	   Allow from all
+    
+
+Note, the only new thing is the first line. Ensure that labhamsterproject/settings_local.py contains the following setting:
+
+    ADMIN_MEDIA_PREFIX = '/media/'
+
+... restart apache and verify that the Django layout is fine.

+8.2 Troubleshooting Database access
 --------------------------------------
 
 In practise, on ubuntu-server, I received an ugly OperationalError: complaining that the database could not be accessed by the user. Read more about postgresqp authentication issues here:
 http://www.depesz.com/2007/10/04/ident/
 
 The problem is resolved by editing pg_hba.conf (located in /etc/postgresql/9.1/main) and adding a line right after the first "local" statement:
 
     # Database administrative login by Unix domain socket
     local   all             postgres                                peer
     ## customization for django user
     local   labhamster      all                                     trust
 
 This basically means that all users arriving from within the server (rather than through TCP/IP from outside) can use the labhamster database without password authentification. Now restart postgrespql and apache:
 
     sudo /etc/init.d/postgresql restart
     sudo apache2ctl restart
