How to programmatically create a service and add new layers?

[TedChapin]

I can create an empty service using gis.content.create_service
This empty service has
layers=[]
tables=[]
I can get the service item's FeatureLayerCollection and use  .manager.update_definition to update the definition of the service including service-level properties.

But, how to create a new feature layer (or table) and add it to the service's definition?

Reviving this question as I am also looking for a solution to this.

Anyone have a solution for this or a link to a sample?

Here is a link where I started: https://community.esri.com/t5/geodev-germany-blog/publish-multiple-layers-in-one-feature-service-on/...

Example: create the empty service and add a point layer. Once created you can use methods to add/append data.

from arcgis.gis import GIS
from arcgis.features import FeatureLayerCollection

"""Access AGOL"""
agol = GIS("home")

"""paramters for the create_service method"""
name = "NAME_OF_FS"
has_static_data = False # want to be able to edit
max_record_count = 1000
capabilities = "Query,Extract,Create,Update,Editing,Delete",
service_type = "featureService"
tags = ["TEST", "Feature", "Service"]
snippet = "User generated feature service"

"""create the empty feature service"""
empty_service_item = agol.content.create_service(
    name = name,
    has_static_data = has_static_data,
    max_record_count = max_record_count,
    capabilities = capabilities,
    service_type = service_type,
    tags = tags,
    snippet = snippet
)

"""the feature layer defintion template. Note: print a feature layers properties to screen to see more definitions, see previous video Access Feature Layer and View Properties."""

## access as FeatureLayerCollection
flc = FeatureLayerCollection.fromitem(empty_service_item)

"""update the JSON definition fof the feature service to iclude the layer"""
flc.manager.add_to_definition({"layers": [fl_definition]})

[MarcelBeckmann]

Thanks, I get an Error: FeatureLayerCollection is not definded.

Is the following correct:

flc = features.FeatureLayerCollection.fromitem(empty_service_item)

When I use this I get the following Error:

Service Hosted/SERVICENAME/MapServer not found

[Clubdebambos]

I forgot the from arcgis.features import FeatureLayerCollection at the top of the script. I have added.
