Attribute rule to pass intersecting grid summary into street names table

[bbaker_tngeo]

I am trying to summarize multiple road segments with the same name (e.g. Main St) into an array, that I can then write to a single line in a table within the same datastore. I found a similar workflow suggestion by @JohannesLindner but I do not have a relationship between the road feature class and the master road name table and I am concatenating values in an array instead of summing to a total.

Before this rule runs, there is another rule that Intersects the line segment being created or updated with a grid/map index which is the "IntersectingGrids" field below.

Here's what I have so far:

/ Get all features with the same LineID
var line_id = $feature.LineID;
var query = "LineID = + @line_id";

var roads = Filter($featureset, query);

// Output array
var grid_arr = [];

// Sort function for later
function grid_sort(a, b){
    if (a > b){
        return 1;
    } else {
        return -1;
    }
}

// Check if records exist
if (Count(roads) > 0) {
    
    for (var row in roads) {
        
        // split value by commas
        var items = Split(row.IntersectingGrids, ',', -1, true);
        
        for (var i in items) {
            
            // trim any whitespace    
            var grid_value = Trim(items[i]);
            
            // Check if grid value already in array
            if (Find(grid_value, grid_arr) == -1){
                
                // Add to array
                Push(grid_arr, grid_value);
            }
        }
    }
    
    // Sort grid_arr with custom sort function
    var sorted = Concatenate(Sort(grid_arr, grid_sort), ', ');
} else {
    return 'No records.';
}

var lineListExpression =;
var lineListFeatures = FeatureSetByName($datastore, 'Line_List', ['GridList1'], false);

var features = Filter(lineListFeatures,  "LineID = '" + line_id + "'")

But I am not sure where to go after that.

I have a batch attribute rule in the Line_List table that works, although it does not update if there is already something in the field. Ideally, when a change is made to a road segment (geometry edit or road name change), the GridList field in the master road names table would automatically update.

//This batch rule is saved in the Line_List table and works to summarize the various line segments and group them by LineID, then produce a summary array, but it does not update when changes are made to the road segments in the feature class.

// Output array
var grid_arr = []

// Sort function for later
function grid_sort(a, b){
    if (a > b){
        return 1
    } else {
        return -1
    }
}

var lineID = $feature.LineID


// Get related records
var segments = FeatureSetByName($datastore, "Line", ['LineID', 'Test_txt'], false)
var segment_data = Filter(segments, "lineID = '" + $feature.LineID + "'")

// Check if related records exist
if(Count(segment_data) > 0){
    
    for (var row in segment_data){
        
        // split value by commas
        var items = Split(row.Test_txt, ',', -1, true)
        
        for (var i in items){
        
            // trim any whitespace    
            var grid_value = Trim(items[i])
            
            // Check if grid value already in array
            if (Find(grid_value, grid_arr) == -1){
            
                // Add to array
                Push(grid_arr, grid_value)
            }
        }
    }
    
    // Sort grid_arr with custom sort function
    var sorted = Sort(grid_arr, grid_sort)

    // Return concatenated string of array values
    return Concatenate(sorted, ', ')
} else {
    return 'No records.'
