Increment

Adds custom method .increment() #109

.increment (criteria, field[, amount][, cb])

Increments the given field by amount (defaults to 1). This can be used to generate sequencial numbers, more about this in OrientDB docs.

usage:

  // Given a model Counter with attributes `name` and `value`
  Counter.increment({ name: 'counter1' }, 'value', function (err, counter) {
    console.log('counter1 has increased by 1 to:', counter.value);
  });

  // To decrement use negative numbers
  Counter.increment({ name: 'counter1' }, 'value', -2)
  .then(function (counter) {
    console.log('counter1 haas decreased by 2 to:', counter.value);
  });
