gistfile1.txt

		$conditions = array_merge($conditions, array(
			'Profile.cb_ohip' => $healthcare_provider,
		));
		return $this->User->Profile->find('all', array(
				'contain' => array(
						'Shift' => array(
								'fields' => array('id', 'date'),
								'conditions' => array(
										'Shift.date >=' => $start_date,
										'Shift.date <=' => $end_date,
								),
								'ShiftsType' => array(
									'fields' => array('id', 'shift_start', 'shift_end'),
									'Location' => array(
										'fields' => 'location')),
								'User' => array(
									'fields' => array('name'),
								))),
				'fields' => array('cb_ohip'),
				'conditions' => $conditions,
				'recursive' => '3',
		));
