FeatureLayerCollectionManager references a missing function in overwrite()

HåkonDreyer — Sun, 12 Dec 2021 17:02:38 GMT

After publishing a hosted service based on a gdb we would like to regulerly update the service using the overwrite functionality in Python API 1.4.1.

This works fine if the service resides in AGOL, but when trying the same in Portal the API throws an error. Apparently the FeatureLayerCollectionManager calls an unimplemented method: _overwrite_portal.

Traceback (most recent call last):
  File "c:\test\overwrite.py", line 19, in <module>
    _fcoll.manager.overwrite(_data)
  File "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\features\managers.py", line 1030, in overwrite
    return self._overwrite_portal(data=data_file)
AttributeError: 'FeatureLayerCollectionManager' object has no attribute '_overwrite_portal

In managers.py this is implemented as this, which also explains the difference between AGOL and Enterprise:

Håkon Dreyer‌, thanks for pointing out, I have fixed this bug and will be available in v1.4.2.

Meanwhile, you can safely comment out those two lines (1029, 1030) and overwrite functionality should work for all supported cases.

Hi Atma Mani‌ , I see you fixed the issue in 1.4.2, but I'm afraid there still might be some unsolved issues when posting to a Portal.

My testscript runs fine when posting to Online, but fails like this on Enterprise 10.5.1 and 10.6 portals.

Hi - Atma Mani, just tested the aforementioned update bug with the new 1.5 API, but except for the line numbers nothing seems to have changed.

Still works fine with ArcGIS Online.

Ping Atma Mani, seems the bug lives on, just tested with 1.5 on a 10.6.1 portal.

Same problem, 10.6 portal. Does the commenting out lines 1029 and 1030 in managers.py circumnavigate the bug on 10.6 portal?

Hi, and no. Removing those lines only fixed the missing function problem, but update of items in portal still fails.

I found the same thing, commenting out that function results in error further down

Finally fixed with 1.5.1. and 10.6.1 portal

Hi Håkon,

I'm getting the same error: 'FeatureLayerCollectionManager' object has no attribute '_overwrite_portal'

I'm not sure if our portal install captured the fix.

Was it in a patch?

Thanks!

Hi, Craig

it was a bug in the 1.4.1 ArcGIS Python API. The missing function was fixed in 1.4.2, but additional bugs made the functionality unusable until 1.5.1.

Have you updated the ArcGIS API to the latest version?

Re: FeatureLayerCollectionManager references a missing function in overwrite()

deleted-user-Qrnw90viByMg — Thu, 10 Jan 2019 20:48:53 GMT

Håkon,

I had not done that. I didn't realize the API doesn't get updated when ArcGIS Pro gets updated, or that I had to do it manually.

I took your suggestion, and it's working now.

Thank you!

Håkon Dreyer‌,

I spoke too soon. My errors went away, but I'm not seeing any updates in the portal layer. The feature count stays the same, and the dates don't change. I do, now, have the latest version of the API installed, but is there anything else? Is there a patch for Portal or Datastore I need to use?

Re: FeatureLayerCollectionManager references a missing function in overwrite()

HåkonDreyer — Mon, 21 Jan 2019 08:08:58 GMT

Too bad, but don't think there are any specific patches needed. I just tested the API 1.5.2 on an unpatched 10.6 Portal and it worked nicely. Could you share your code or tell a bit more about your scenario?

Håkon- thanks for responding.

I wonder if I'm missing something in the script, then. Here's what I have:

from arcgis.gis import GIS,Item,User
from arcgis.features import FeatureLayer Collection
from datetime import datetime as dt
import os,getpass

s_time=dt.now()
print('Started at: ' + str(s_time))

try:
    gis=GIS('https://portal.myportal.org/portal',username='gisadmin',password='mypassword')
    user=User(gis,'gisadmin',None)
    for item in user.items():
        if item['title'] == 'Feature service overwrite test':
            if item['type'] == 'Feature Service':
                my_item = item
                print("overwriting '{0}'".format(my_item['title']))
    my_flayer_collection = FeatureLayerCollection.fromitem(my_item)
    
    update_src = 'C:\\Users\\' + getpass.getuser() + '\\Documents\\ArcGIS\\overwrite_test.gdb\\overwrite_data'
    my_flayer_collection.manager.overwrite(update_src)

    f_time=dt.now()
    print('successfully updated {0} at {1}'.format(my_item['title'],str(f_time)))
    print('time elapsed: ' + str(f_time-s_time))

except Exception:
    print(str(sys.exc_info()[1]))

I appreciate your help with this! Thanks

Hi, Craig

finally had a look at your code. My guess is that your problem is the update_src.

update_src = 'C:\\Users\\' + getpass.getuser() + '\\Documents\\ArcGIS\\overwrite_test.gdb\\overwrite_data'
my_flayer_collection.manager.overwrite(update_src)

The overwrite function expects a zipped geodatabase, not a feature class, so try zipping the gdb.

Re: FeatureLayerCollectionManager references a missing function in overwrite()

deleted-user-Qrnw90viByMg — Fri, 01 Feb 2019 17:19:17 GMT

Thanks, Håkon.

I gave that a try, but this time I got a "Job failed" message. The geodatabase I zipped only contains a single feature class, and it exactly matches the feature service I'm trying to update.

Is there anything special I need to do with the geodatabase, or any other ideas? I appreciate your help!

Thanks again!

Hi, hard to tell what causes the problem. If it may be to any help I've uploaded my test script and two tiny gdb's here. Just unpack the zip and edit Portal and Path info.

Håkon Dreyer - thanks..

While I was trying these solutions, I was simultaneously working with ESRI Support, and we came up with a different workflow which publishes a new SD file. That is working well, so I won't need to pursue this solution, though it appears it would be a simpler script.

Thanks for your help!
