Add Feature Class to Current Pro Project Via Script Tool

Hello,

I replied to this post where the user had the same issue I'm experiencing. Since it was a Pro question I decided to repost here in Python.

The problem I'm facing involves my custom script tool not adding a feature class to an open Pro project. I'm using Pro 2.8.

Working from a notebook, this successfully adds a feature class to the map.

import arcpy, os data = r'path\to\BaseLayer_Processed_Elementary_08302021_clip' arcpy.env.addOutputsToMap = True try: arcpy.management.MakeFeatureLayer(data, data) except: print(arcpy.GetMessages())

But, according to the docs the above only creates a temp layer in the map. So, unless you save the map or export the layer to a feature class it won't be saved. So, I tried the below script:

import arcpy, os data = r'path\to\BaseLayer_Processed_Elementary_08302021_clip' arcpy.env.addOutputsToMap = True try: # Write the selected features to a new featureclass arcpy.CopyFeatures_management(data, os.path.basename(data)) except: print(arcpy.GetMessages())

Both scripts work to add a feature class to the map. However, when I convert to a script tool to run within pro it runs successfully, but nothing is added to the map.

Tool version of the script:

import arcpy, os #input feature class from model. It will be added to the map. data = arcpy.GetParameterAsText(0) arcpy.env.addOutputsToMap = True arcpy.AddMessage(f'adding to map: {data}') try: #Copies features from the input feature class or layer to a new feature class. arcpy.CopyFeatures_management(data, os.path.basename(data)) except: arcpy.AddMessage(arcpy.GetMessage())

this is checked on as well?

Dan,

Didn't realize that was there. It's checked on, anyway.

I do something similar with the code below to add a layer to the map that is currently open in ArcGIS Pro. My code runs from a python toolbox - not sure if it applies to what your are doing

aprx = arcpy.mp.ArcGISProject('CURRENT') current_map = aprx.activeMap current_map.addDataFromPath(<path to feature class>)

I think Don has the solution/work-around, I think notebooks rely on this approach rather than the checkbox for project defaults.

I do vaguely remember data not being added to the map before, which I thought was resolved, but it does make sense since a toolbox tool really doesn't know what the active project or active map is, particularly for toolboxes that reside in a different path that the project folder.

That works. It makes sense that the script tool didn't know the map. Thanks for pointing that out. Nowhere did I come across .activeMap in the help pages.

dir .... often uncovers the unincluded

proj = r"C:\arcpro_npg\npg\Project_npg\npGeom.aprx" aprx = arcpy.mp.ArcGISProject(proj) dir(aprx) ['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__from_scripting_arc_object__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_arc_object', 'activeMap', 'activeView', 'dateSaved', 'defaultGeodatabase', 'defaultToolbox', 'documentVersion', 'filePath', 'homeFolder', 'importDocument', 'listBrokenDataSources', 'listColorRamps', 'listLayouts', 'listMaps', 'listReports', 'metadata', 'save', 'saveACopy', 'updateConnectionProperties']

.... help on those properties and methods is quite limited though

print(aprx.save.__doc__) ArcGISProject.save() Saves changes to an ArcGISProject ( .aprx ).
