    <p>Please, here is the updated code, with empty arrays and everything. It is in plain javascript so no library needed. Its jut a crude example I know, but it works and I hope it will help you to find your way.Later you can refine it.</p> <pre><code>var stops = { "Stops": [ { "Lat": 38.92092, "Lon": -77.043684, "Name": "COLUMBIA RD NW + MINTWOOD PL NW", "Routes": [ "42", "43", "H1", "L2" ], "StopID": "1001779" } ] }, predictions = { "Predictions": [ { "DirectionNum": "1", "DirectionText": "North to Mt Pleasant Via Adams Morgan", "Minutes": 7, "RouteID": "42", "VehicleID": "7136" }, { "DirectionNum": "1", "DirectionText": "North to Mt Pleasant Via Adams Morgan", "Minutes": 25, "RouteID": "42", "VehicleID": "7103" }, { "DirectionNum": "0", "DirectionText": "North to Chevy Chase Circle", "Minutes": 32, "RouteID": "L2", "VehicleID": "2207" }, { "DirectionNum": "1", "DirectionText": "North to Mt Pleasant Via Adams Morgan", "Minutes": 36, "RouteID": "42", "VehicleID": "7132" }, { "DirectionNum": "1", "DirectionText": "North to Mt Pleasant Via Adams Morgan", "Minutes": 58, "RouteID": "42", "VehicleID": "7111" }, { "DirectionNum": "1", "DirectionText": "North to Mt Pleasant Via Adams Morgan", "Minutes": 69, "RouteID": "42", "VehicleID": "7135" } ], "StopName": "Columbia Rd Nw + Mintwood Pl Nw" }; var routeTimes = {}; for (var index in predictions.Predictions) { if(!routeTimes.hasOwnProperty(predictions.Predictions[index].RouteID)) { routeTimes[predictions.Predictions[index].RouteID] = []; routeTimes[predictions.Predictions[index].RouteID].push(predictions.Predictions[index].Minutes); } else { routeTimes[predictions.Predictions[index].RouteID].push(predictions.Predictions[index].Minutes); } } var routes = stops.Stops[0].Routes, routesVsMinutes = {}; for(var i in routes) { if (!routesVsMinutes.hasOwnProperty(routes[i])) { routesVsMinutes[routes[i]] = {Minutes: []}; } if (routeTimes[routes[i]]) { routesVsMinutes[routes[i]].Minutes = routeTimes[routes[i]]; } } stops.Stops[0].Routes = routesVsMinutes; console.log(stops); </code></pre>

    1. COThanks Vlad, this is really close! Now the next trick is to add blank arrays for routes that don't have predictions in routeTimes

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
