A script to export attachments from ArcGIS Pro 3, based on a "CleanID" field on the base (non-attach) table. Will export files in the passed directory, named like `ATT{CLEAN_ID}.jpg`
import os
from functools import lru_cache
import arcpy
from arcpy import da
base_table = arcpy.GetParameterAsText(0)
files_dir = arcpy.GetParameterAsText(1)
if not (base_table and files_dir):
arcpy.AddError("Expected two arguments: the base table, and a directory to save files")
if base_table.endswith("__ATTACH"):
arcpy.AddWarning("Expected a base table as first parameter, does it really end in __ATTACH already?")
attach_table = base_table + "__ATTACH"
def get_clean_id(global_id) -> str:
global_id = str(global_id)
field = arcpy.AddFieldDelimiters(base_table, "GlobalID")
where_clause = "{} = '{}'".format(field, global_id)
with da.SearchCursor(base_table, ["GlobalID", "CleanID"], where_clause) as cursor:
items = list(cursor)
if len(items) != 1:
raise Exception("Expected a single item in the base table with global id")
item = items[0]
return str(item[1])
with da.SearchCursor(attach_table, ['DATA', "REL_GLOBALID", "ATT_NAME"]) as cursor:
for item in cursor:
data, rel_globalid, att_name = item
att_name = str(att_name)
if "." not in att_name:
# Take a guess
att_name += ".jpg"
clean_id = get_clean_id(rel_globalid)
# Modify this line to change the file name, the first `{}` will be replaced with the clean_id,
# the second `{}` will be replaced by the "ATT_NAME` field from the attach table ("Photo 1.jpg")
filename = "ATT_{}_{}".format(clean_id, att_name)
with open(files_dir + os.sep + filename, "wb") as f:
del data
del item
