mankind / create dropdown ie hyku authority or controlled vocabulary
Last active July 7, 2020 09:30
Add multipart metadata fields to samvera active_fedora models
Your next task is to turn the audience field into a dropdown and the dropdown options are 'particpant', 'spectator', 'graduate', 'apprentice'
See http://samvera.github.io/customize-metadata-controlled-vocabulary.html
1. Create a yaml file conatining vocabularies ie dropdown names in config/authorities with thesame name as your field. So if your field is funder, you will have
config/authorities/funder.yml eg https://github.com/ubiquitypress/hyku/blob/test/config/authorities/funder.yml
http://samvera.github.io/customize-metadata-controlled-vocabulary.html#create-a-vocabulary
In that file, add the values you want in your dropdown following the format above.
2. Create a service to load the dropdown names or vocabularies in app/services/
