Adding attachments using layer.edit_features fail

See original GitHub issue

When using layer.edit_features() to add attachments the method fails and returns None. This is caused by your requirement of one of the methods adds, deletes or updates to be part of the call. image

You should add and "attachments" not in params as well.

Until fixed a workaround is to add an empty deletes=""

        _res = _layer.edit_features(deletes="", use_global_ids=True, gdb_version=_ver, attachments={'adds':[_att]})

Ok I see what you are saying. We will further investigate these issues.

Sure, I trust you to find a suitable feature service and attachment file.

import os
import base64
import uuid
import mimetypes
import arcgis

# File to attach
_attach = "c:/temp/test.txt"
# Create base64 string
with open(_attach,'rb') as _file:
    _data =
    _data64 = base64.b64encode(_data).decode('ascii')

# Get a layer and a feature to attach to
_gis = arcgis.GIS('pro')
_ds = "https://your.server/server/rest/services/yourservice/FeatureServer/0"
_layer = arcgis.features.FeatureLayer(_ds, _gis)
_feat = _layer.query(result_record_count=1, return_all_records=False, out_fields='OBJECTID,GlobalID')

# Create attachment
_att = {
    'globalId': str(uuid.uuid4()),
    'parentGlobalId': _feat.features[0].attributes['GlobalID'],
    'contentType': mimetypes.guess_type(_attach)[0],
    'name': os.path.basename(_attach),
    'data': _data64

# Add and fail
_res = _layer.edit_features(use_global_ids=True, attachments={'adds':[_att]})

# Add with empty deletes
_res = _layer.edit_features(deletes="", use_global_ids=True, attachments={'adds':[_att]})
