Would it be possible to add the 10.3 functionality “Pagination” to the .query() method of arcrest.agol.services.FeatureLayer and arcrest.ags.layer.FeatureLayer ???

Hello Andrew,

FeatureLayer.query with returnCountOnly-flag results in an error ...

QryRes = FL.query ( returnCountOnly=True )

Traceback (most recent call last): File "", line 1, in File "C:\Python27\ArcGIS10.3\lib\site-packages\arcrest\agol\services.py", line 1793, in query return FeatureSet.fromJSON(jsonValue=json.dumps(result)) File "C:\Python27\ArcGIS10.3\lib\site-packages\arcrest\common\general.py", line 617, in fromJSON for feat in jd['features']: KeyError: 'features'

Applying the new(?) resultOffset parameter has no effect: QryRes = FL.query ( returnFeatureClass = True, out_fc = FC_Full, resultOffset = 100 ) delivers the same features as with resultOffset=0

Applied to a FeatureService with 108 records: len(FL.query(resultOffset=0).features) gives 108 len(FL.query(resultOffset=50).features) gives 108 (should be 58)

In these examples ... FL = arcrest.ags.layer.FeatureLayer ( URL ) URL = 'http://tmservices1.esri.com/arcgis/rest/services/LiveFeeds/Earthquakes/MapServer/0' ( AGOL features ) or URL = 'http://scomp1250:6080/arcgis/rest/services/Roland/SpotFootPrints/FeatureServer/0' ( a local feature service with 108 polygons )

Bye, Roland

Hello Andrew, Mike,

FL.query ( returnCountOnly=True ) is functioning normal again, and FL.query ( resultOffset=500 ) works as well ! I just had to be more critical which service(s) to query. Only if it mentions "Supports Pagination: true" then it's OK

Thanks ! Roland
