🎁 IiifPrint Re Split PDF on command

[ShanaLMoore]

Summary

LaRita has a WIP PR that covers the backend work required for this feature 🎉 (this has not been tested yet).

We need to create a frontend button or interface, on a PDF fileset, that would trigger the backend behavior.

consider user permissions - the user should be able to edit.

Before starting, ask Jeremy for notes

Tasks

• Leverage https://github.com/samvera/hyrax/blob/b334e186e77691d7da8ed59ff27f091be1c2a700/app/views/hyrax/file_sets/_show_actions.html.erb file to add the link/button to POST a request a split (within the if @presenter.editor? ... block)
  • only render this new button when the file set is a PDF
• Create a decorator for the Hyrax::FileSetsController with the split_pdf action
  • When the FileSet is not a PDF raise an exception (e.g. FileSet is expected to be a PDF) (Note: We'll want this in cases where the above conditional failed and yet here we are. The exception will report to Sentry)
  • When the FileSet is a PDF we want to spawn a job to perform the splitting
• Create a job that wraps the above PR
• Add a route that POSTs to the newly created action; you'll likely need that route to have a :id parameter so that the decorator will properly behave.
• Add to Adventist (updating routes)

Considerations

(Jeremy here): I had thought about creating a separate controller, to avoid the decorator pattern. That separate controller would be IiifPrint::PdfSplitsController. The action would be create and follow the above guidance. Advantages would be keeping the controller space clear.

I have several projects located on my machine; and it looks as though we have not overriden the file_sets behavior. See details:

`cd ~/git; fd _show_actions.html | rg file_sets`

hyrax/app/views/hyrax/file_sets/_show_actions.html.erb
hyrax/spec/views/hyrax/file_sets/_show_actions.html.erb_spec.rb
dlp-curate/app/views/hyrax/file_sets/_show_actions.html.erb

Acceptance Criteria

• When a user clicks a button, the PDF should split (or re-split).
