[Archivesspace_Users_Group] ASpace Version 2.8.0, custom plugin throwing error, "language"

[Andrew Morrison]

The simple "language" property of resources and archival objects (which 
I assume is what is held in the obj variable in your code), that held a 
single ISO 639/2 language code, was scrapped in 2.7.0. Instead, there is 
now a "lang_materials" property, holding a much more complicated data 
structure, to allow multiple ISO 639/2 language codes and/or language 
notes to be added to a record. Here's how the core ArchivesSpace MARCXML 
exporter handles that:


https://github.com/archivesspace/archivesspace/blob/3851abd72727270e6c07b5d1bfe7efdcda55c9f5/backend/app/exporters/models/marc21.rb#L137-L144
