Programmatic Access to Editing Properties of Feature Service

McKinneyPatrick_PA — Mon, 16 Sep 2024 13:16:33 GMT

I am writing a script to identify if publicly-shared services have editing enabled. I would like this to correspond to the "Update" option listed under "What kind of editing is allowed" on an item's page in ArcGIS Online/Portal.

According to the REST API, I thought that checking for "Editing" or "Update" in the layer or tables "properties.capabilities" would return this information.

However, after testing my script, I learned that these do not match up. Is there a way to use the Python API to get a listing of what is enabled for editing that matches what is listed on the item's page?

Hi @McKinneyPatrick_PA

Is the below what you are looking for?

from arcgis.gis import GIS from arcgis.features import FeatureLayerCollection ## access ArcGIS Online agol = GIS("home") ## get the Feature Service as an Item object item = agol.content.get("ITEM_ID") ## FLC represents a Feature Service flc = FeatureLayerCollection.fromitem(item) print(flc.properties)

From these you can get the information from the settings page that acts as a master control for all layers and tables in the Feature Service. You can also use the API and the FeatureLayer object to update some capabilities for individual layers and tables.

## Create - Create a feature (editing) ## Query - Query attributes of a feature ## Update - Update feature attributes and geometry (editing) ## Editing - All editing capabilities (Create,Update,Delete) ## Extract - Extract data in various formats ## Sync - Used for offline data use and collaborations ## Delete - Delete a feature (editing) ## ChangeTracking - keep track of editing changes "capabilities": "Create,Delete,Query,Update,Editing,Sync,ChangeTracking" "allowGeometryUpdates": true "allowTrueCurvesUpdates": true "onlyAllowTrueCurveUpdatesByTrueCurveClients": false ## only availabkle if Editor Tracking has been enabled "editorTrackingInfo": { "enableEditorTracking": true, "enableOwnershipAccessControl": false, "allowOthersToQuery": true, "allowOthersToUpdate": true, "allowOthersToDelete": true, "allowAnonymousToQuery": true, "allowAnonymousToUpdate": true, "allowAnonymousToDelete": true } ## only available of Change Tracking is enabled "extractChangesCapabilities": { "supportsReturnIdsOnly": true, "supportsReturnExtentOnly": true, "supportsReturnAttachments": true, "supportsLayerQueries": true, "supportsGeometry": true, "supportsFeatureReturn": true, "supportsReturnHasGeometryUpdates": false, "supportsReturnDeletedFeatures": true, "supportsServerGens": true, "supportsFieldsToCompare": true }

I would recommend turning on and off different settings and printing the properties and looking for changes/additions to the output JSON to see what is affected.

All the best,

Glen

The issue is that the "capabilities" property does not match the "Add/Delete/Update" checkboxes on the item's page.

I was expecting if "Add" shows up on the item page, it would also show up in "capabilites." But things did not match up this way.

Ahh, right. I haven't seen that behaviour before.

The issue was on my mis-understanding of capabilities. I was originally checking for either "Editing" or "Update."

After re-reading @Clubdebambos comments, I realized I should only have been checking for "Update" capability.
