Unable to edit Associations table

ducroix_magis

Hello,

I try to edit the associations table with the REST or GIS API, however I get an error when using deleteFeatures or applyEdits

--> AGS Logs, no additional logs in FINE or VERBOSE mode

SEVERE

An error occurred.

When doing it programmatically in python, I get this error :

Is it possible to edit this table through the REST or GIS API ?

Hello,

I opened a case, and they created an enhancement request

ENH-000173298 - Add a sample code in the UN documentation regarding how to edit the 500001 association table with the arcgis Python API

On our side, we use REST API instead of ArcGIS API to delete associations

MilesWacker1

Were you able to get anywhere with this, do you have a case or bug #?

I'm running into the same thing, I can add associations no problem with the python api but cannot delete them. Can add update delete all other layers no problem, just not delete associations. My error is:

{'error': {'code': 500, 'extendedCode': -2147467259, 'message': 'Unable to complete operation.', 'details': ['Unable to perform applyEdits operation.', 'Error: This operation is not allowed while editing [gdb_version_name].']}}

ducroix_magis

I rewrote my code, and I am now sure that there is a bug with Association table editing with the ArcGIS API for Python.

My code works well when passing a standard featureLayer or Table, but not when passing the UN Asso Table.

It gives me an Error : this operation is not allowed while editing (Error Code: 500)

I will log a case with the support.

I haven't had a chance to test out using the FeatureLayer object yet, but you could try doing that by global ID or object ID.

If you can't find a path forward via the ArcGIS API for Python, but can produce a correct result using the REST endpoint directly, I'd recommend you log a case with support. We could either expose the appropriate ArcGIS API for Python object, or determine why directly editing the layer doesn't work.

ducroix_magis

After validating the dirty area, the association is now deleted, thank you.

Do you know any way to apply edits on the service with the ArcGIS API for Python ? Or will I have to do REST requests like I did manually ?

rkrisher

@PierreloupDucroix Deleting an association, through rest or the user interface, only logically deletes the association. Once you validate the edit, updating the system tables, the association will be physically deleted from the version. 33 = 32 + 1 = The "To feature" in the association is dirty and the association is deleted. This means when the association was logically deleted we placed a dirty area on the "to object" so it could be validated using the map.

ducroix_magis

1- yes, my user has the built-in admin account

2- I can't find how to get the Asso layer from the Version object... Listing all version.layers layers does not return the 500001 layer...

3- trying this

featureLayer.delete_features(deletes=oids, gdb_version=gdb_version, rollback_on_failure=True)

results in the error :

ERROR: 2024-11-07 10:53:05,333 - ERROR - Error: Unable to complete operation.
Unable to perform applyEdits operation.
An error occurred.
(Error Code: 500)

Finally, when applying edits directly on the service, it results in a success... but it seems to have no effect because I can still find the globalId in the same version after the applyEdit...

[
 {
  "id": 500001,
  "deleteResults": [
   {
    "globalId": "{D75D19CD-99E7-415C-B866-006A5E113720}",
    "success": true
   }
  ]
 }
]

[EDIT] : it IS working when deleting from the service, in Default or Named versions. However, I can still query the feature, but the Status field changed from 0 to 33, probably indicating that the row has been deleted.

[EDIT 2] Reading the doc (https://pro.arcgis.com/en/pro-app/latest/help/data/utility-network/associations-table.htm#GUID-DF91CB8D-FB2B-4DAF-A62C-D9AEC597733D) I am not sure how to interpret the 33 Status value...

rkrisher

Try using the applyEdits method on the service and pass in the layer id and global id of the feature you want to delete.

rkrisher

I'll test this out on my end, here are my initial observations:

Please double-check that the credentials used to create the service connection either have the built-in role of Administrator or have a custom role that includes Version Management capabilities.
The feature layer you are editing exists prior to you establishing the connection to the connection to the service. I recommend you get a reference to the layer from the layers object on the version management object to ensure you are using the same connection and version you connected to.
Another thing you could consider is using the delete_features method instead of edit_features.

Hi Robert

this was the code I was using :

def DeleteFeatures(featureLayer, oids: list, gdb_version: str = VERSION) -> None:
    if len(oids) == 1:
        result = featureLayer.edit_features(deletes=oids, gdb_version=gdb_version)
        AnalyzeEditResults(result)
    else:
        maxRecordCount = featureLayer.properties.maxRecordCount
        _oids = list(_divideChunks(oids, maxRecordCount))
        for k, oidsChunk in enumerate(_oids, start=1):
            logger.debug(f"chunk {k} sur {len(_oids)}")
            result = featureLayer.edit_features(deletes=oidsChunk, gdb_version=gdb_version)
            AnalyzeEditResults(result)

However, with your helpful advice and this link (https://support.esri.com/en-us/knowledge-base/how-to-edit-branch-versioned-feature-layers-using-the-a-000032186), I changed to :

def DeleteFeatures(featureLayer, oids: list, gdb_version: str = VERSION,
                   version_management_server_url: str = VERSIONMANAGEMENT) -> None:
    try:
        portal, featureServerItem = _MakeConnectionToService()
        vms = _getVersion(version_management_server_url, portal)
        with vms.get(gdb_version, "read") as version:
            version.start_editing()
            if len(oids) == 1:
                result = featureLayer.edit_features(deletes=oids)
                print("success")
                AnalyzeEditResults(result)
            else:
                maxRecordCount = featureLayer.properties.maxRecordCount
                _oids = list(_divideChunks(oids, maxRecordCount))
                for k, oidsChunk in enumerate(_oids, start=1):
                    logger.debug(f"chunk {k} sur {len(_oids)}")
                    # sessionId = "{" + f"{uuid.uuid4()}" + "}"
                    # result = featureLayer.edit_features(deletes=oidsChunk, gdb_version=gdb_version, session_id=sessionId)
                    result = featureLayer.edit_features(deletes=oidsChunk)
                    AnalyzeEditResults(result)
            version.stop_editing(save=True)
            version.mode = None
    except Exception as err:
        print("Error: {0}".format(err))

Now I have the following error :

Error: The operation is not supported against the default version.
(Error Code: 0)

It may be because the Default version is protected... but my user have version management capabilities and is admin.

rkrisher

It should work, and when it fails I would expect something a bit more meaningful than a 500 errors. This implies something deeper is going wrong. What version/patch of enterprise are you on, and is there a crash dump that corresponds to this?

Can you post the script you're using for Python? I'm assuming that you're doing this against default and that you're starting a read then edit operation, but a script will be more informative. Having access to your script also lets me test it out on my server 😁
