Accessing M-N and 1-M related table records in Portal Pop-ups
Hello, I'm an Arcade newbie trying to modify the pop up for the parcels in a web map that serves as the basis for a Portal web application. The parcels feature layer in question has a pairing of relationship classes set up to other tables in the published Map Service. This Service, called "TL_Parcels_Activities" is added to the web map and called "Tidelands Activities" in the Contents.
It contains six different items with a different definition query on the parcels source data, a feature class in our geodatabase called "TL_Parcels".
TL_Parcels has a Many-to-Many relationship to the PI Numbers table, which, in turn, has a One-to-Many relationship to the Tidelands Activities table.There is also an additional 1-M relationship set up to a Site ID table. All of these tables and relationship class tables were included in the Map Service and show up in the web map.
The Related Records show up in the pop-up to open the related data in tabular form well enough...
... but I was hoping to use Arcade to get the related info to appear in the pop-up directly, without having to click and read in the attribute tables themselves.
I found some good examples of script suggestions on GeoNet for some 1-M situations that I tried out. I think folks were using these for AGO, which I understand has some quirky differences from the Portal environment. I started with this sample: How do you reference another field from a related table in Arcade?
My initial attempts kept giving me the error:
"Execution Error:Runtime Error: Identifier Not Found. $map"
I found an example that focused on the GlobalID that I decided to run with and still got the same problem.
Get 1:M related objects using Arcade
// read the GlobalID of the feature
var globalid = $feature.GlobalID;
// create a sql expression to filter the asset table
var sql = "gis_id = '" + globalid + "'";
// Access the Activities based on the name in the map
var ACTIV_view = FeatureSetByName($map, "TL_PINumbers");
// filter the assets using the sql expression
var ACTIV = Filter(ACTIV, sql);
// get the count of the related Activities
var cnt = Count(Activities);
// create a variable to hold the resulting text
var ACTIV_info = "";
// validate if there are any related records and handle accordingly
if (cnt > 0) {
// there is at least 1 related record, create activity info
ACTIV_info = cnt + " Activities:";
// loop through related records
for (var activity in Activities) {
// create text using name and description (you should modify this to match your needs)
var ACTIV_text = " - " + Activity.name + TextFormatting.NewLine + Activity.description;
// add the text for this activity to the activity info
ACTIV_info += TextFormatting.NewLine + ACTIV_text;
}
} else {
// no related records (or the sql query did not work)
ACTIV_info = "No related Activities";
}
return ACTIV_info;With these I could never access the $map from the Globals tab. Despite the fact that all of these other things were in the same web map, all I could see were the $feature for all of the fields in the Parcels feature class.
As a test, I separately published a Hosted Feature Layer of the parcels/relationships which shows the two related tables, but not the relationship classes themselves, within the service.
Then I added that to my web map and tried to use the same Arcade expression on that layer. $map was now accessible to me in the Globals and the code seemed to get past that sticking point, but gave me an Execution Error: Filter cannot accept this parameter type.
I'm not always exactly sure what the sample scripts are asking for everywhere, so I'm not fully sure I'm putting the correct info where it belongs. I also know that I will probably need to do more to this to add all the attribute info I want to display and probably to get the script to go to the next level for the other 1-M relationship between the two tables.
Thanks.

Hi Roger,
Thank you for the reply and the scripting.
Tried it with this, just attempting to get the first bit of info, The PI Number field, out of the table:
var relatedrecords = OrderBy(FeatureSetByRelationshipName($feature,"TL_Parcels_Activities - TL_PINumbers"), "TL_PINumber");
var cnt = Count(relatedrecords);
var relatedinfo = "";
if (cnt > 0) {
var info = First(relatedrecords);
relatedinfo = info.PI_NUMBER;
}
return relatedinfo;
… and got the Execution Error: Runtime Error: Function Not Found: FeatureSetByRelationshipName
That sounds like the function is not usable for that task or in the Portal environment.
Part of what I’m wondering is if the related table and identifier info should be listed as it actually is in the data or as it shows in the web map.
This is the way the service shows up with its tables in our portal:
The TL PINumbers table is actually called TL_PINumbers in our data. Not sure if that matters.
I’m hoping that if I can get the PI Number from the this table to appear in the popup, then all I would have to do is then list those other fields as well, even though they reside in that next level relationship table. But I’m not sure if I shouldn’t be using one of the other tables listed above or not.
I’m not sure if the presence of the tables for the Relationship Classes that are set up for this (TL RS ToPINumbers) confuses things at all or not. Or if that should be the table that is used instead. This just has the two items that are compared.
Then there is the SiteID Composite table which shows the connection to the relationship [Related PI Number(s)].
The TL Activities table is the second level 1:M relate that shows all the additional info in the fields above that we also want to have listed ultimately.
Hope that isn’t too confusing! Below is a sketched diagram of how the tables are connected:
The other table referring to SiteID is a separate second level relationship branch that is not anything we are worrying about showing.
Thanks for your help!
Matt
