Arcpy Append - How to load a .fieldmap file

CW-GIS — Wed, 23 Oct 2024 19:05:08 GMT

Good afternoon,

I have a standard append script, how could I just load the a fieldmap file that I saved?

Append = arcpy.management.Append(inputs=[feature_class], target=hosted_feature, schema_type="NO_TEST", field_mapping="***Load FieldMap File***")

Hi @CW-GIS can you post an example of your fieldmap file?

Also, have you seen the example of using Field Mappings in the following example?

Append takes FieldMappings objects that can be created using a .loadFromString:

import arcpy import os def load_fieldmap(path: os.PathLike) -> arcpy.FieldMappings: with open(path, 'r') as fieldmap: return arcpy.FieldMappings().loadFromString(fieldmap.read()) arcpy.management.Append( inputs=["C:/path/to/input.gdb/input"], target="C:/path/to/output.gdb/output", schema_type="NO_TEST", field_mapping=load_fieldmap("C:/path/to/fieldmap.fieldmap") )
