Hello,
I'm trying to publish a GeoJSON file containing lines and points to ArcGIS Online. The publication process is successful, resulting in a Feature Layer with two layers - point and line. Everything looks fine, except that all attributes are automatically converted to the "string" type. I've attempted to modify the attribute types using the following code, but I haven't achieved the desired outcome. The attributes still remain as "string" instead of the intended "date" type.
# Name of the layer you want to load
layer_name = "Test GeoJSON File"
# Retrieve the Feature Layer through search
layer = gis_agol.content.search(query=layer_name, item_type="Feature Layer")[0]
# Get the Feature Layer object
feature_layer = layer.layers[0]
# Retrieve information about the attribute table of the Feature Layer
attributes = feature_layer.properties['fields']
# Define new attribute types to be used
new_types = {
"realizace_do": "esriFieldTypeDate",
# Continue with other attributes you want to modify
}
# Update the attribute types in the attribute table of the Feature Layer
for attribute in attributes:
attribute_name = attribute['name']
if attribute_name in new_types:
attribute_type = new_types[attribute_name]
attribute['type'] = attribute_type
feature_layer.manager.update_definition({'fields': attributes})
