Ist es möglich, Daten direkt auf der Leinwand zu visualisieren? Verwendung von ArcgisEnterprise.getdatafromfeturelayer

felipe_crcom

Hallo,

ich versuche, eine App mit Live-Daten aus einem Feature-Layer in meinem Portal zu erstellen. In Power Automate kann ich die Verbindung testen und ArcgisEnterprise.Getdatafromfeturelayer verwenden, um Daten abzurufen, daher weiß ich, dass der Connector und der Feature-Layer zugänglich sind.

Was PowerApps betrifft, habe ich nur die veraltete Version der Funktion (getfeaturelayerdata), die nicht funktioniert.

I am doing something similar right now. I'm not visualizing points, just data. But it is working.

I found running a similar flow in Power Automate before creating the PowerApp was best. If you inspect the Power Automate run, it gives you everything that PowerApps is expecting to see.

I just did a proof of concept this week, and likely am not going to do anything serious with this app until January now. But I can at least share what I have so far.

In the app's OnStart property:

// 1) Call ArcGIS connector
Set(
    varProjectsJson,
    ArcGISEnterprise.GetFeatureLayerData(
        "My content",
        "<URL>", //If you're unsure what this URL should be, you should first run a flow in Power Automate using the same connector. Inspect the flow and you will see the full URL needed
        "JSON",
        {
            returnGeometry: false, //true if you want point data. I haven't tried this yet.
            where: "1=1",
            outFields: "*", //I'm lazy and grab everything.
            startingCount: 0
        }
    )
);
// 2) Normalize to text, then parse to untyped objects. May not be needed. I had may issues with this and have yet to optimize the workflow
Set(
    varText,
    JSON( varProjectsJson, JSONFormat.IncludeBinaryData )   // guarantees Text for ParseJSON()
);
// 3) Coalesce the possible outcomes. Same as step #2. This shouldn't be needed, but optimization will come later.
With(
    {
        rows:
            Coalesce(
                ParseJSON(varText).body.data,
                ParseJSON(varText).data,
                ParseJSON(varText)
            )
    }, //Create the collection for use in gallery
    ClearCollect(
        colProjects,
        ForAll(
            rows, //customize rows and also set type. The names, like "ProjectName" are internal and can be anything (avoid spaces and special characters). The things after "attributes" are specific to your data.
            {
                ProjectName:        Text(ThisRecord.attributes.prname),
                ProjectLongName:    Text(ThisRecord.attributes.prlongname),
                PM:                 Text(ThisRecord.attributes.pm),
                PM_Email:           Text(ThisRecord.attributes.pm_email),
                Province:           Text(ThisRecord.attributes.custlocation_province),
                City:               Text(ThisRecord.attributes.custlocation_city),
                Address:            Text(ThisRecord.attributes.custlocation_addressline1),
                PostalCode:         Text(ThisRecord.attributes.primarypostalcode),
                Status:             Text(ThisRecord.attributes.status),
                ProjectNumber:      Text(ThisRecord.attributes.wbs1),
                ObjectID:           Value(ThisRecord.attributes.objectid)
            }
        )
    )
);

 

In my Canvas app, I have a Text Input (txtSearchWBS1) and a Gallery (galProjects).

 

For the Gallery's Items, I use this formula. All I'm doing is using the Text Input to filter my data based on ProjectNumber. If the Text Input is blank or the user enters less than 5 characters, the Gallery is blank.

With(
    {s: Trim(txtSearchWBS1.Value)},
    If(
        Or(IsBlank(s),Len(s)<5),
        Filter(
            colProjects,
            false
        ),
        Filter(
            colProjects,
            StartsWith(
                Upper(ProjectNumber),
                Upper(s)
            )
        )
    )
)

 

And that's it. End result is a PowerApp that queries a Feature Layer.
