FeatureLayerCollection issues

YS2388 — Wed, 22 Nov 2023 19:49:42 GMT

Hello,

I am relatively new to the python API. There is something I am not understanding about featurelayercollections (flc). In AGOL, I have a feature service with a point layer and a related table. This is feature service is an flc:

According to the documentation, I should have access to properties such as "relationships" or "manager". I wanted to use the flc manager to add a layer to the service but running the code:

flc.manager.insert_layer("path")

An error: 'Item' object has no attribute 'manager'

What am I missing here?

Thanks,

Based on the error and other provided information, it seems you are working with a FeatureCollection Item and not a FeatureCollection object.

Try doing this:

from arcgis.features import FeatureLayerCollection flc = FeatureLayerCollection.fromitem(flc_item)

where "flc_item" is what you are currently working with

Thank you for the clarification Earl! That was the issue. A few things I noticed:

flc.manager.layers - Returns related table as part of the layers list.

flc.manager.tables - Does not recognize related table, returns an empty list.

flc.relationships - returns an empty list. I am not familiar with the "supportsRelationshipsResource" property...

Thank you.
