Python Toolbox / regular Toolbox -- postExecute not working

Yanu — Sun, 01 Oct 2023 16:53:40 GMT

Hey guys,

I am dealing with unable to use postExecute method within Python Toolbox or atbx toolbox.

class Tool(object‌‌ def __init__(self‌‌): """Define the tool (tool name is the name of the class).""" self.label = "Tool" self.description = "" self.canRunInBackground = False def getParameterInfo(self‌‌): """Define parameter definitions""" param1 = arcpy.Parameter( displayName="Dos", name="param1", datatype="DEFeatureClass", parameterType="Required", direction="Input") param2 = arcpy.Parameter( displayName="Output Features", name="out_features", datatype="GPFeatureLayer", parameterType="Derived", direction="Output") return [param1, param2] def execute(self, parameters, messages‌‌): """The source code of the tool.""" param1 = parameters[0].valueAsText gdb = "gdb_path" out = f"{gdb}/layer2" arcpy.CopyFeatures_management(param1, out) arcpy.SetParameter(1, out) arcpy.AddMessage("Tool has finished executing222") return def postExecute(self, parameters, messages‌‌): """This method takes place after outputs are processed and added to the display.""" arcpy.AddMessage("Tool has finished executing!!!!!!!!!!!!!!!!!!!!") try: project = arcpy.mp.ArcGISProject('CURRENT') active_map = project.activeMap if active_map: out_layer = active_map.listLayers(os.path.basename(self.params[1].valueAsText))[0] symbology = out_layer.symbology symbology.updateRenderer('SimpleRenderer') symbology.renderer.symbol.applySymbolFromGallery('Airport') symbology.renderer.symbol.size = 12 out_layer.symbology = symbology except Exception: pass return

I've used example from documentation, has anyone had any success with using postExecute?

Do I need to execute it someway?

Code is basic, just for testing purpose.

regards,
Yanu

What does the toolbox look like? That is where you execute the tool from within your project's toolbox

Toolbox is like this:

import arcpy import os class Toolbox(object): def __init__(self): """Define the toolbox (the name of the toolbox is the name of the .pyt file).""" self.label = "Toolbox" self.alias = "toolbox" # List of tool classes associated with this toolbox self.tools = [Tool]

Default, postExecute is also from documentation.

They suggested using postExecute:

Yes that is the code, but have you added the toolbox to your project and tried to execute it?

Catalog, Project tab, Toolboxes with my toolbox which has a tool with a toolset and a tool shown

which you can launch and run to test whether it works or check its properties

for tool validation... (postExecute is commented out here since none is needed)

Thank you for your reply Dan.

Yes, I've added this Python Toolbox to project.

I tried also setting up ATBX from scartch and testing if postExecute will run.

Nothing happens...

postExecute is new. Are you using ArcGIS Pro 3.x?

Re: Python Toolbox / regular Toolbox -- postExecute not working

Yanu — Sun, 01 Oct 2023 20:54:34 GMT

I know, I am using 3.1.1.
I've checked patch notes, 0 bugs...

Which leaves the thread you posted BUG-000155515 for ArcGIS Pro (esri.com)

so I would open an Issue with Tech Support so they can investigate why it isn't working.... I don't use postExecute in my toolboxes

Hi Yanu, Dan and Luke
I'm using ArcGIS Pro 3.3 and have same problems with "postExecute" routine.
It seems do nothing.
Any news from the BUGS?

BUG-000155515 for ArcGIS Pro (esri.com) still lists the status as "known limitation"

so contacting Tech Support would be your best option
