Attribute Rule when splitting a line

DominicRobergeIADOT

Hello,

I am looking for an Attribute Rule that would allow me to split a line (water main) and for one segment retain the original unique ID and the other segment, get the next available ID. Is that doable?

Any guidance would be much appreciated.

Thanks!

I just tested it, and I think it's failing because of lines 52-54. If the field already has an ID value, it doesn't get overwritten. If it's empty, it gets a new ID. Try commenting out those lines and splitting the line.

Thank you! That did the trick. I though I had tested it before but I guess not.🤣

Yes, if I create a new line, no problem I get the next UID as expected. The issue is when splitting a line .

Does the above code work when digitizing completely new line features?

DominicRobergeIADOT

that doesn't seem to be working for me. Below is the code I am using (which is from the UN water foundation)

var assigned_to_field = $feature.FUID;
var id_selector_value = $feature.assetgroup;

function get_id(selector_value) {
    var id_format = {}
    var seq_val = null;
    var selector_value_txt = Text(selector_value)
    if (selector_value_txt == '1') {
                            id_format = {
                                'prefix': "DRSQ1",
                                'join_char': '',
                                'suffix': ''
                            }
                            seq_val = NextSequenceValue('DR_DB_SEQ_1');
                        }else if (selector_value_txt == '50') {
                            id_format = {
                                'prefix': "Wr-Jnctn",
                                'join_char': '-',
                                'suffix': ''
                            }
                            seq_val = NextSequenceValue('W_J_Wr_Jnctn_50_seq');
                        }else if (selector_value_txt == '51') {
                            id_format = {
                                'prefix': "Insltn-Jnctn",
                                'join_char': '-',
                                'suffix': ''
                            }
                            seq_val = NextSequenceValue('W_J_Insltn_Jnctn_51_seq');
                        } else {
        return null;
    }
        var id_parts = remove_empty([id_format['prefix'], seq_val, id_format['suffix']])
        return   id_format['prefix'] + Text(seq_val , "00000")
    }
// ************* End User Variables Section *************

// *************       Functions            *************
function remove_empty(arr) {
   var new_arr = [];
   var j = 0;
   for (var i = 0; i < Count(arr); i++) {
       if (!IsEmpty(arr[i]) && arr[i] != '') {
           new_arr[j++] = arr[i];
       }
   }
   return new_arr;
}

if (IsEmpty(assigned_to_field) == false && assigned_to_field != '') {
            return assigned_to_field
}
var new_id = get_id(id_selector_value)

if (IsEmpty(new_id)) {
    return assigned_to_field;
}

return new_id

If you have an attribute rule setup that assigns a new ID "on insert", the action of splitting the line should cause the shorter segment of the line to be created as a new feature, which would trigger the attribute rule and give that line segment a new ID. The longer segment of the original line would retain the original ID.
