How to set "Display Value" condition of the reference field of the target table in "View Rule" script?

[Aki17]

I created a View Rule to automatically change Views between Portal and internal platform, with the condition like below:

If
- u_application_id is "1"
AND
- Accessed from Service Portal
Then
Apply "u_1_portal" View

Else if
- u_application_id is "1"
AND
- Accessed from internal platform (NOT portal)
Then
Apply "u_1" View

"u_application_id" is the reference field, so I set "sys_id" in the IF condition, but I would like to use "display value" which it's easier to specify the condition value.

Could someone please modify the following script to set condition based on display value of "u_application_id" field instead of sys_id?

(function overrideView(view, is_list) {
 //get URL details
 var url = gs.action.getGlideURI().getMap();

 //Determine if in portal view
 var isPortal = url.get('id');
        var sys_id = url.get('sys_id');
        if(sys_id){
 var gr = new GlideRecord('u_shinsei');
        if(gr.get(sys_id)){ 
   if(gr.u_application_id == 'sys_id' && isPortal){
    answer = 'u_1_portal';
   }
   if(gr.u_application_id == 'sys_id' && !isPortal ){
    answer = 'u_1';
   }
  }
  }else{
   answer=null;
  }
})(view, is_list);

Best Regards,

Aki

Could you try the below with the getDisplayValue() method?

(function overrideView(view, is_list) {
 //get URL details
 var url = gs.action.getGlideURI().getMap();

 //Determine if in portal view
 var isPortal = url.get('id');
        var sys_id = url.get('sys_id');
        if(sys_id){
 var gr = new GlideRecord('u_shinsei');
        if(gr.get(sys_id)){ 
   if(gr.getDisplayValue('u_application_id') == 'Give display value' && isPortal){
    answer = 'u_1_portal';
   }
   if(gr.getDisplayValue('u_application_id') == 'Give display value' && !isPortal ){
    answer = 'u_1';
   }
  }
  }else{
   answer=null;
  }
})(view, is_list);
