ArcGIS JavaScript App - Edit Geoprocessing Widget Results Display

JoshuaFarrow — Fri, 03 Apr 2015 18:01:57 GMT

As part of my JavaScript App, using Web AppBuilder, I created two geoprocessing widgets. One allows the user to input a user defined area to calculate population density (Zonal Statistics as Table tool). After the tool has ran, the geoprocessing widget returns a table with the following fields:

Rowid	FID	COUNT	AREA	SUM

Is it possible to configure the results to only display the SUM field? Something like "Total Population: [SUM]" in the results tab.

My other geoprocessing widget allows the user to input a user defined area to calculate the total number of structures within a given area (Spatial Join). The results are drawn on the map - making the user select the output polygon to retrieve the count total. Similar to my first question, is it possible to display the structure count within the geoprocessing results tab opposed to on the map within a polygon?

Thank you.

Did you have any luck figuring this out? I also wanted to do something similar and format a return values number of decimal places..

did you ever figure this out? I did something like it so let me know.

For now, WAB doesn't have this feature.

Junshan-

Any idea when these might be a feature in AGOL? I've been doing a pretty thorough search without luck on where to get started on attempting a GP, and it seems to be a fairly requested item.

Thanks

What are you trying to do with the GP service?

I am trying to calculate geometry on features in a table, much like you would calculate geometry in ArcMap. This operations doesn't have to be a GP but seems to be the only real option in this case. Many users I deal with will never touch ArcMap, so it isn't an option to send them there, nor are they willing to wait for me to do it for them

Everything to date with WAB for measuring lines/polygons has been through the draw tool;

ArcGIS API for JavaScript Sandbox.

I have used ArcMap and python to create a GP service that calculates offset so I think it would be possible to do what you are wanting to do..

Terry - So I thought I would give the GP a try, but instead of calculating geometry (acres) on a field in a table in WAB, I get a whole new export. My steps were;

Calculate Field GP on the desired field in ArcMap with expression: !shape.area@acres!
Share data and GP as a REST service (output table same as input table)
Examine GP REST (Note: the output is "out_data" and type is "GPFeatureRecordSetLayer")
Add data REST to new webmap, create new WAB template
Add GP REST to WAB GP widget
When running GP tool within WAB, the output is a completely new table (as expected based on GP REST)

So, I'm curious how exactly did you do this offset using a GP? By the way - I'm also looking into using the Geometry engine in the ESRI JS API.

I did a linear offset for routes, what kind of offset are you wanting to perform?

Terry -

I'm not really looking for an offset, as a calculation of acres on a specific column within the Hosted Feature Layer itself. From the examples and the documentation, it would appear that you can use a Hosted Feature Layer to calculate a derivative (i.e. buffer), but the Hosted Feature Layer cannot be the output in the GP process.

TerryGustafson — Thu, 10 Mar 2016 15:56:28 GMT

So you are wanting to calculate acres from a specific column in a hosted feature layer?

Re: ArcGIS JavaScript App - Edit Geoprocessing Widget Results Display

RobertMueller_Jr1 — Thu, 10 Mar 2016 16:00:05 GMT

Yes, that is exactly what I am trying to do. I understand this is not a feature of the current ESRI Javascript API or ArcGIS WebApp builder, but surely I could string a few things together to make this possible.

Re: ArcGIS JavaScript App - Edit Geoprocessing Widget Results Display

TerryGustafson — Thu, 10 Mar 2016 16:36:40 GMT

Yeah I would just create a model in the model builder with the layer you want to calculate and then use the calculate field tool. Then create the GP and you should be able to add the calculate item in WAB.

RobertMueller_Jr1 — Thu, 10 Mar 2016 16:55:36 GMT

Terry-

I've tried using the ESRI "Calculate Field" python script which works on a Feature Class to calculate an entire field (using: !shape.area@acres!), but if you swap the Feature Class with the Hosted Feature Layer, you run into an error because the Hosted Feature Layer is not editable in ArcMap.

I've been exploring using the "Calculate" as part of the ESRI REST to perform the same operation.

Is your hosted feature layer public?

Re: ArcGIS JavaScript App - Edit Geoprocessing Widget Results Display

TerryGustafson — Thu, 10 Mar 2016 17:44:29 GMT

Sorry for all of the questions, is the hosted layer owned by you? Do you have that layer in SDE? Is this layer static?

Re: ArcGIS JavaScript App - Edit Geoprocessing Widget Results Display

RobertMueller_Jr1 — Thu, 10 Mar 2016 18:30:00 GMT

No problem. I very much appreciate the help. I am an Admin to AGOL and yes this is a Hosted Feature Layer owned by me. I'm currently following you, if you want to send me a message I can provide 2 different dummy Hosted Feature Layers that are open to the public.
