Instance Method Details

#create_content(file) ⇒ Object

Puts the uploaded content into a staging directory. Then kicks off a job to characterize and create derivatives with this on disk variant. Simultaneously moving a preservation copy to the repostiory. TODO: create a job to monitor this directory and prune old files that have made it to the repo

Parameters:

  • file (File, ActionDigest::HTTP::UploadedFile, Tempfile) —

    the file uploaded by the user.

def create_content(file)
  # Assign label and title of File Set is necessary.
  file_set.label ||= file.respond_to?(:original_filename) ? file.original_filename : ::File.basename(file)
  file_set.title = [file_set.label] if file_set.title.blank?

  # Need to save the file_set in order to get an id
  return false unless file_set.save

  working_file = copy_file_to_working_directory(file, file_set.id)
  mime_type = file.respond_to?(:content_type) ? file.content_type : nil
  IngestFileJob.perform_later(file_set.id, working_file, mime_type, user.user_key)
  make_derivative(file_set.id, working_file)
  true
end

#create_metadata(work, file_set_params = {}) {|file_set| ... } ⇒ Object

Adds the appropriate metadata, visibility and relationships to file_set

Note: In past versions of Sufia this method did not perform a save because it is mainly used in conjunction with create_content, which also performs a save. However, due to the relationship between Hydra::PCDM objects, we have to save both the parent work and the file_set in order to record the “metadata” relationship between them.

Parameters:

  • work (ActiveFedora::Base) —

    the parent work that will contain the file_set.

  • file_set (Hash) —

    specifying the visibility, lease and/or embargo of the file set. If you don’t provide at least one of visibility, embargo_release_date or lease_expiration_date, visibility will be copied from the parent.
