How to use getbeans and relationship field - suitecrm

Question

I'm setting up a logic hook in suitecrm to allow nc case to emailed to the department the issue is raised to however; I keep getting the error message "Could not find Users within the department NC is issued to; indicating that dept_array is equivalent to zero. I'm to using getbeans and relationship tables. I created the relationship dept_department_nccas_nc_case in suitecrm but there's no data inside the table so I'm wondering if that's the reason or if my syntax is incorrect.
class nc_email_notification {
public function email_notification(&$bean, $events, $arguments){
/*define 'review_pending' as string constant */
/*Get sugar email engine*/
$email = new SugarPHPMailer();
$email->From = 'suitecrm#gmail.com';
$email->FromName ='SuiteCRM';
/*Get the Department NC was Issued to */
$dept_array= $bean->get_linked_beans('dept_department_nccas_nc_case','dept_Department_sugar');
if(count($dept_array)==0){
/*log error*/
$GLOBALS['log']->fatal("Could not find the department NC was issued to: ". $bean->name);
}else{
/* Get email of users within the Department NC is issued to */
$user_array = $dept_array[0]->get_linked_beans('dept_department_users','User');
if(count($user_array)==0){
/*log error*/
$GLOBALS['log']->fatal("Could not find Users within the department NC is issued to: ". $bean->name);
}else{
$address=getDepartmentUsersEmail($user_array);
}
/*Get the Department NC was raised by */
$raised_dept_array= $bean->get_linked_beans('dept_department_nccas_nc_case_1','dept_Department_sugar');
if(count($raised_dept_array)==0){
/*log error*/
$GLOBALS['log']->fatal("Could not find the department NC was raised by: ". $bean->name);
}else {
/*Get email of users within the Department NC is raised by*/

Relationship names are tricky! I always get them wrong so here is a snippet that will let you find the exact name
$m1 = 'Users';
$m2 = 'ACLRoles';
print_r(getRelationshipByModules($m1, $m2));
$m2 = 'Users';
$m1 = 'ACLRoles';
print_r(getRelationshipByModules($m1, $m2));
Please note that the order matters so that's why I repeat the sentence twice but in different order.
Change m1/m2 for the module you want to know the relationship name and then do get_linked_beans
