Reference Qualifier to filter locations based on User Location

[mattfollowell]

I have a variable on a catalogue item that references the locations table. I want that variable to only list locations whose parent = the signed in user's location. EXCEPT if the signed in User's location = MG. If the signed in user's location is MG then I want the variable to list all locations on the table.

function advloc() {
var locPar;
var userLoc='';
var gr=new GlideRecord('sys_user');
gr.addQuery('sys_id',gs.getUserID());
gr.query();
    while(gr.next()){
        userLoc=gr.location;
    }
    if(userLoc.includes("MG")){
        locPar = "";
    }
    else {
        locPar = "parent = userLoc";
    }
return locPar
}

I think it is not working because it returns the name of the location and not the Sys_Id, but I'm not 100%.

Hi there,

Several things  to look at:

gr.location
> is a sys_id
userLoc.includes("MG") 
> Checks for a string, not a sys_id
> Not sure, though I don't think includes work. Use indexOf('MG') > -1 instead
>>> Do note: this checks if it contains MG. So what if there is a location "AMG"... not what your where after, though still matches. So a small bug here to fix!

Maybe more, though start with this.

If my answer helped you in any way, please then mark it as helpful.

Kind regards,

I would try the following script:

function advloc() {
    var locPar;
    var userLoc = '';
    var gr = new GlideRecord('sys_user');
    gr.addQuery('sys_id', gs.getUserID());
    gr.query();
    if (gr.next()) {
        userLoc = gr.location + "";
    }

    if (userLoc.indexOf("MG") == -1) {
        locPar = "";
    } else {
        locPar = "parent=" + userLoc;
    }
    return locPar
}

This points me in the right direction, but doesn't work as an advanced reference qualifier for the variable.. I might need to rethink the way I am doing this.
