How to update layer properties in FeatureLayerCollection?

TraceStanford1 — Sun, 12 Dec 2021 11:07:32 GMT

So I know you can update the properties of a FeatureLayerCollection by using a dictionary...My question is: how can you update the layer properties? The layers are a list in the properties dictionary, and I can't figure out how to update the name of a layer, for example...

{
  "layers": [
    {
      "id": 0,
      "name": "gggg",
      "parentLayerId": -1,
      "defaultVisibility": true,
      "subLayerIds": null,
      "minScale": 0,
      "maxScale": 0,
      "geometryType": "esriGeometryPoint"
    }
  ]
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I'm using a dictionary to try and update, but can't figure out the proper syntax to access the layer name and update it...

update_dict = {
  "serviceDescription": 'newname',
  "layers":[ 
    {
      "name": 'newname',
    }
    ]
}‍‍‍‍‍‍‍‍

Hi Trace - I'm assuming you are in ArcEnterprise? Anyway, you can update the title of an Item using the update method in the Item class, but to update the layer name you have to do a service rename using the Service class in the server module. It basically creates a new service with the same id as the old service. It's kind of a pain

I am trying to change the name of a hosted feature layer published to AGOL, so it's not on our server. Can you connect to AGOL with the server module? I thought it was for connecting to a server that had ArcGIS Server or Portal...

Doesn't look like it. If you go here

arcgis.gis.admin module — arcgis 1.7.0 documentation

you'll see that the AGOLAdminManager has no 'servers' module. The best you'll be able to do is change the title of the item. I'm constantly running into little constraints like this. For example, I want to set the content_status property of my layers to 'org_authoritative', or 'public_authoritative' for AGOL. So even though contentStatus is a property of an item because I can see it in the items' json, it is ignored in the item_properties dictionary because the api doesn't seem to provide 'content_status' as value pair. Super frustrating.

That is frustrating. I'll figure out another way then. Thanks for the help!

Hi Trace,

ArcGIS Online Assistant

This is your friend. You can edit the metadata for most of the layers that you own.

AGO Assistant is one of the most useful tools that i have encountered for AGO or Portal.
