Add the following lines to /etc/hosts:

# Local testing
172.16.214.42   api.whosup.local whosup.local

# Pagodabox
50.97.141.37    api.whosup.com whosup.com

Remember to change 172.16.214.42 to either 127.0.0.1 or the IP belonging to your local virtual machine

Apache setup

To point the domains ´whosup.local´ and ´api.whosup.local´ to their respective local folders, create a new virtual hosts by creating the file /etc/apache2/sites-available/whosup:

<VirtualHost *:80>
    DocumentRoot /srv/www/whosup
    ServerName  whosup.local
    LogLevel debug
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot /srv/www/whosup/api
    ServerName  api.whosup.local
</VirtualHost>

Remember to change /srv/www/whosup to your own local path

Last stuff Enable the virtual host: sudo a2ensite whosup

Enable rewriting: sudo a2enmod rewrite

Restart Apache: sudo service apache2 restart

LEFT JOIN transactions on transactions.id = subtransactions.transaction_id
GROUP BY user_id, group_id
UNION
SELECT -SUM(amount) as balance, group_id, borrower_id as user_id FROM subtransactions
LEFT JOIN transactions on transactions.id = subtransactions.transaction_id
