Overview

HasManyPurgable

Mark your model with ‘has_many_purgable’ or ‘has_one_purgable’ (both the same thing) to allow any has_many_attached or has_one_attached to be purgable.

Pass ‘has_many_purgable :files, :avatar’ to only allow the files and avatar to be purged.

Works with effective_bootstrap file_field to display a Delete file on save checkbox to submit a _purge array of attachments to purge.

You must permit the attribute _purge: []
