rmela is proud to present you this little tip:

Og mysql connection parameters

Assuming you can connect using the mysql command line client with a password

mysql -u myusername -h 127.0.0.1 -p

then these are the Og parameters:

Og.options = {
# :destroy => true,
  :store => :mysql,
     ## database name #
  :name => 'mydatabase',
     ## integer, not string #
  :port => 3306,
  :user => 'myusername',
  :address => '127.0.0.1',
  :password => 'mypassword'
}

Trivial, but timesaving for a newbie.
