Return All Operational Layers of Web Map Item

Please have the all the operational layers within a web map returned when using "layers" of a Web Map item.

It seems that any layers within a Group Layer are skipped, meaning the user has to check whether the layer is a group layer and then further iterate over the layers within the group to truly retrieve all layers within the web map.

Below is an example. The grouped layers are expanded to show all the layers within the web map:

In the code below, the layers within the "PLSS", "Annotation", and "Political Township" group layers are not returned.

import arcgis # portal connection variables portal_url = r'...portal url...' portal_user_name = '...user name...' portal_user_password = '...user password...' # target web map web_map_id = '...web map id...' # connect to portal p = arcgis.GIS(portal_url, portal_user_name, portal_user_password) # set web map item item = p.content.get(web_map_id) # set web map item web_map = arcgis.mapping.WebMap(item) # get operational layers layers = web_map.layers for l in layers: layer_name = l.get('title') layer_type = l.get('layerType') print(f'{layer_name} ({layer_type})')

None of the layers within the group layers (green line) are returned. It would be nice if they were returned without having to iterate through each group layer object.

Checkout the new mapping module (arcgis-mapping package) that was just released. We added a way to add and look through group layers!

arcgis version 2.4.0
