Changing basemap to a gallery_basemaps item

KarenRobine1 — Tue, 17 Aug 2021 19:32:06 GMT

Hello:
I'm using custom basemap's defined as a WebMaps gallery_basemaps (https://developers.arcgis.com/python/api-reference/arcgis.mapping.toc.html#arcgis.mapping.WebMap.gallery_basemaps)

According to the example under a WebMaps property, basemap, I should be able to set my webmap to a gallery_basemap item. If I'm creating a new webmap, this works perfectly. However, if I'm updating an existing basemap, it fails saying there is not a gallery-basemaps

ie.

wm = WebMap(webmap_item)

wm.basemap = <my_unique_basemap_name_from_the_gallery>

Exception: 'WebMap' object has no attribute '_gallery_basemaps'

Ideas?

I am experiencing the same. How do I add our enterprise portal basemaps to an enterprise portal web map? Thanks.

I have attached a notebook in the zip file.

I was able to switch the basemap of a portal webmap to a basemap from another portal web map with the notebook. Hopefully this will help. Let me know if you have questions. Thanks.

Thank you for this post and these examples. It aided in developing this notebook. I wanted to share in case it was useful. ArcGIS Online Basemap Replacement Notebook Update
