unable to access webmap definition in version 2.4

TrishPeller — Wed, 04 Dec 2024 21:16:35 GMT

I have a script that, in version 2.3, accesses the webmap definition property ("wm.definition"). This property does not appear to be refactored in the new Map class (it's not listed here: https://developers.arcgis.com/python/latest/guide/overview24/). Is there another way to access the webmap definition that I'm missing?

Hi @TrishPeller

It is not present as a property for the Map class. You can access the same information using the Item object get_data() method.

from arcgis.gis import GIS ## access AGOL agol = GIS("home") ## get the WebMap Item as an Item object wm_item = agol.content.get("WM_ITEM_ID") ## get the WebMap definition wm_def = wm_item.get_data() print(wm_def)

This works for me, thank you!

I'm relatively new at working with this api. Is it common for ESRI to introduce a bunch of breaking changes with a minor version update? That is not a good recipe for a good developer experience.

In short, yes. Big breaking changes with arcgis.mapping / arcgis.map between v2.3 and 2.4. The release notes are informative, but often not super helpful for addressing breaking changes.
