I am attempting to use ArcGIS API for Python to overwrite the underlying data of a hosted feature layer with an shapefile. As this layer is used within a Web App and has pre-configured filters, it cannot simply be replaced with a new layer.
Workflow
1) Published the service
# publish shapefile as feature service
gis = GIS("https://anonymous/arcgis/")
zip_path = '\\\\<anonymise>\\GDW_Catalogue_Items_OS.zip'
published_item = gis.content.add(
item_properties = {
"type": "Shapefile",
"title": parent,
"description": "printed maps and charts",
"tags": "GDW, Catalogue, Footprints, Printed Maps, Printed Charts",
},
data = zip_path,
overwrite=True
)
published_layer = published_item.publish()
# share published feature layer with groups
published_layer.share(groups=['3214a47ac81e4c839a044edf7c42e5ab', '3b3f17e9f2b84aeda789e337da033a7f', 'b4856c293ab84eb389ab323979bd253d', '404b73b5e78b49a0863f8a8cb0f1b6ce'])
2) Sometime later, I wanted to update the data using a new Shapefile:
# Access hosted feature layer
gis = GIS("https://anonymous/arcgis/")
search_results = gis.content.search('title:GDW_Catalogue_Items_OS AND type:Feature Service')
feature_layer_item = search_results[0]
# feature collection
from arcgis.features import FeatureLayerCollection
feature_layer_collection = FeatureLayerCollection.fromitem(feature_layer_item)
# call the overwrite() method to update data
zip_path = '\\\\<anonymise>\\GDW_Catalogue_Items_OS.zip'
feature_layer_collection.manager.overwrite(zip_path)
I am given the following error:
