Nope, the OP states zero or *one* department. Although a HABTM relationship
probably makes sense, depending on requirements.
The correct code for the input is:
$this->Form->input('department_id', array('empty' => true)); //renders an
empty option element
//OR
$this->Form->input('department_id', array('empty' => 'No department')); //
renders a "No department" option element with empty value
