[Archivesspace_Users_Group] Adding an element with the API

[Michelle Paquette]

Hi Karen,

I think you're getting the error because it's looking to set those values
on a file version that already exists, and the file version doesn't exist
yet.

I have a script that does something similar and what I've done is create a
definition for a new file version, and then done an "append" on the record
in question (record being the digital object).

def add_thumbnail(thumbnail_uri):
    note_dict =  {'file_uri': thumbnail_uri,
    'publish': True, #change to False if you do not want the file version
to be published.
    'xlink_actuate_attribute': 'onLoad',
    'xlink_show_attribute': 'embed',
    'use_statement': 'image-thumbnail',
    'jsonmodel_type': 'file_version'
    }


Later I have record['file_versions'].append(add_thumbnail)

thumbnail_uri is coming from a spreadsheet. If seeing the full script is
helpful for you please let me know and I'd be happy to share it with you.

Best,
Michelle
