Arcpy Append - How to load a .fieldmap file

CW-GIS

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***")

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")
)
