Looking for a way to query all the Views created from a provided Feature Layer.  In AGOL, this information is provided on the Overview page under the Details : Other Views (see below).  How do I access this  data using ArcGIS API for Python?

Thanks in advanced!

Hi @JaimieNevins2 ,

Here's a sample script which lists all the layer views of a hosted feature layer:

from arcgis import GIS
from arcgis.features import FeatureLayerCollection

gis = GIS("portal_url", "username", "password")

source_item = gis.content.search("feature_layer")[0]
flc = FeatureLayerCollection.fromitem(source_item)
for view in flc.layers[0].manager.properties.adminLayerInfo.layerViews:
    print(view.serviceName)

 

Hope that helps.

Here's an additional solution, to complement @MehdiPira1's.

You can get a list of items that are views of a hosted feature layer by calling related_items with rel_type="Service2Service" and direction="forward":

 

import arcgis
gis = arcgis.gis.GIS("home")
hfl_item = gis.content.get("...")
views_items = hfl_item.related_items(rel_type="Service2Service", direction="forward")
for view_item in view_items:
    print(view_item.title)

 

Conversely, you can get the source hosted feature layer for a view item by calling related_items with rel_type="Service2Service" and direction="reverse":

 

# Returns a list containing only one item.
source_hfl = item.related_items(rel_type="Service2Service", direction="reverse")
source_hfl = source_hfl[0]

How can we get related items of a view ?
