https://community.esri.com/t5/arcgis-online-questions/issue-with-attribute-types-when-publishing-geojson/m-p/1307894#M53349 <P>Hello,</P><P>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.</P><LI-CODE lang="python"># 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})</LI-CODE> Thu, 13 Jul 2023 13:28:04 GMT JiříKomínek 2023-07-13T13:28:04Z https://community.esri.com/t5/arcgis-online-questions/issue-with-attribute-types-when-publishing-geojson/m-p/1307894#M53349 <P>Hello,</P><P>I'm trying to publish a GeoJSON file containing lines and points to ArcGIS Online.
