clone_items() failing when item it pointing to a specific layer in feature service about arcgis-python-api HOT 7 CLOSED

@PleaseStopAsking
Can you update to the latest version of the API and try again?
A lot of effort was put into cloning in the past versions and this might have already been fixed. Let us know if you still see this occurring

from arcgis-python-api.

@nanaeaubry I can attempt to get v2.3.0 running but when I initially attempted to spin up the docker image, it threw errors that I never resolved. This led to using v2.2.0. I will report back once I get v2.3.0 running.

Below is the error from v2.3.0

@PleaseStopAsking
After re-reading your issue it seems you are trying to clone a single layer rather than an item. This is not possible through the API and you have to clone the whole item

from arcgis-python-api.

@nanaeaubry

That is correct. The use-case here is that I need a specific layer from a 3rd party service that is publicly available and instead of adding the entire service as an item in my portal, I point to the individual layer. I can then add this item to any number of web maps or dashboards without having to selectively hide/disable all the other layers that may come with the 3rd party service thus making its usage much easier.

As for it not currently being supported, I can open a feature request to add this in a future release because this would likely benefit others as well.

You can log an enhancement and we will take it under consideration, however this is complicated since you have to read the terms of use of items, even if they are public to make sure they can be cloned/copied. Cloning is already very limited as you have to be the owner of the item you are cloning or an administrator of the org where the item is held (living atlas being an exception).

A better way to do this is to add the layer by url to the apps and maps you want to use it in.

If you really want to copy then you need to check the metadata for the terms and conditions of this. (this is in general for any and all layers you think of using in the future)

You can either download it from the site using the download button: https://hifld-geoplatform.hub.arcgis.com/datasets/75079bdea94743bcaca7b6e833692639_0/explore

Or with the python api you can query into a SeDF and then import it into your portal.

Hope that helps!

@nanaeaubry I am not sure I am following you with regard to the terms of use. If I have created a new feature layer item (non-hosted) in my portal that is simply referencing an external 3rd party feature service, how does cloning/copying that 3rd party service come into play?

The only thing that I would control would be the cloning/copying of the portal item, not the underlying referenced service data. As I would be the admin for both the source and target portals, I have full control to copy/clone the portal items. I just want to ensure I am understanding the issue at play.

Case in point, the Hospital feature service at https://services1.arcgis.com/Hp6G80Pky0om7QvQ/arcgis/rest/services/Hospital/FeatureServer.

If I use that feature service as the basis for a new item in Portal, it does not clone that service into my Portal, but simply references the data when I load it into a web map, etc. Even the description of this type of Portal item states, Link to an ArcGIS Server web service...

@PleaseStopAsking
Some services have privacy terms set up where you are only allowed to reference and not copy so I would just be wary of that.

But to copy I would go the SeDF route described in my previous comment.
