How does Archival Work?

View Source

We make modifications to the resource to enable soft deletes. Here's a breakdown of what the extension does:

Resource Modifications

  1. Adds a private archived_at utc_datetime_usec attribute.
  2. Adds a preparation that filters each action for is_nil(archived_at) (except for excluded actions, or if you have base_filter? set to true).
  3. Marks all destroy actions as soft?, turning them into updates (except for excluded actions)
  4. Adds a change to all destroy actions that sets archived_at to the current timestamp
  5. Adds a change that will iteratively load and destroy anything configured in AshArchival.Resource.archive.archive_related
