Hello, I am trying to automatically overwrite a polyline hosted feature layer using JSON from an API. I think thatI have the correct format for adding the feature layers (shown below), and my issue is with actually publishing/appending the features -- specifically in line 39:
# Main function to fetch API, decode polylines, and publish to ArcGIS Online
def main():
# Make request to API
response = requests.get(api_url)
if response.status_code == 200:
# Assuming API response is JSON with 'features' containing polyline data
features = response.json()
# Extract features from the API data
#features = api_data.get('features', [])
#if not features:
# print("No features found in API response.")
# return
try:
# Truncate existing features in the feature layer
feature_layer.manager.truncate()
# Prepare new features to add
geojson_features = []
for feature in features:
encoded_polyline = feature.get('EncodedPolyline')
description = feature.get('Description')
if encoded_polyline and description:
# Decode polyline from 'EncodedPolyline' field
decoded_polyline = decode_polyline(encoded_polyline)
# Convert to GeoJSON Feature format
geojson_feature = to_geojson_feature(decoded_polyline, description)
geojson_features.append(geojson_feature)
# Add new GeoJSON features to the feature layer
print(json.dumps(geojson_features))
result = feature_layer.edit_features(adds=json.dumps(geojson_features))
print(f"Features updated successfully in ArcGIS Online hosted feature layer.")
except Exception as e:
print(f"Failed to update feature layer: {str(e)}")
else:
print("Failed to fetch data from API.")
This is what is returned by the print(json.dumps(geojson_feature):
[{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[40.77248, -111.8377], [40.77254, -111.83776], [40.7728, -111.83804], [40.7728, -111.83804], [40.77282, -111.83803], [40.77285, -111.83802], [40.77248, -111.8377]]}, "properties": {"Description": "Blue Detour"}}, {"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[40.76466, -111.84503],.............
***Note: I removed the majority of the coordinates, as well as the additional features for simplicity
This is the error that I'm getting, I believe from the result = feature_layer.edit_features(adds=json.dumps(geojson_features)):
pass in features as list of Features, dicts or PropertyMap
Parameters not valid for edit_features
Thank you in advance for any suggestions!
