Enable edit session for particular layer in a versioned geodatabase

SouthCoastGIS

Hello, I am looking to enable an edit session for a particular versioned layer in an ESRI geodatabase. I have a script tool where you select a layer as a parameter, but I get the following error:

RuntimeError: Objects in this class cannot be updated outside an edit session 

So my question is this. Am i able to enable an edit session for a given versioned geodatabase layer through Python scripting, or is there a way to enable an editing session for a layer through model builder before running the script?

 

The script I am attempting to run has this information listed at the beginning.

"""
Assetic.CreateAssetsTbxScript.py
Script to setup as a toolbox script for use in Model Builder
create assets in Assetic from the selected features in ArcGIS layer
Assume Model Builder model has applied a feature selection
This example assumes script is run in an edit session
Requires assetic_esri v1.0.1.4 or later

Using arcpy.GetParameter() returns the object that was input for that parameter when running the tool; whatever you have set as the parameter datatype. In the case of your tool here, if it isGPFeatureLayer or GPLayer, the return value of GetParameter() will be a Layer object so you'll have access to all that object's properties and methods. connectionProperties, dataSource, longName, or name might be the property you're looking for.

 

layer = arcpy.GetParameter(0)


def main(layer):
    arcpy.AddMessage(f"connectionProperties: {layer.connectionProperties}")
    arcpy.AddMessage(f"dataSource: {layer.dataSource}")
    arcpy.AddMessage(f"longName: {layer.longName}")
    arcpy.AddMessage(f"name: {layer.name}")


if __name__ == "__main__":
    main(layer)
