Instance Method Details

#attach_to_work(work, file_set_params = {}) ⇒ Object Also known as: attach_file_to_work

Adds a FileSet to the work using ore:Aggregations. Locks to ensure that only one process is operating on the list at a time.

#create_content(file, relation = :original_file, from_url: false) ⇒ IngestJob, FalseClass

Spawns asynchronous IngestJob unless ingesting from URL Called from FileSetsController, AttachFilesToWorkJob, IngestLocalFileJob, ImportUrlJob

Parameters:

  • file (Hyrax::UploadedFile, File)

    the file uploaded by the user

  • relation (Symbol, #to_s) (defaults to: :original_file)

Returns:

  • (IngestJob, FalseClass)

    false on failure, otherwise the queued job

    # If ingesting from URL, don't spawn an IngestJob; instead
    # reach into the FileActor and run the ingest with the file instance in
    # hand. Do this because we don't have the underlying UploadedFile instance
    file_actor = build_file_actor(relation)
    file_actor.ingest_file(wrapper!(file: file, relation: relation))
    # Copy visibility and permissions from parent (work) to
    # FileSets even if they come in from BrowseEverything

    InheritPermissionsJob.perform_later(file_set.parent)
  else
    IngestJob.perform_later(wrapper!(file: file, relation: relation))
  end
end

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

Note:

In past versions of Hyrax 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.

Adds the appropriate metadata, visibility and relationships to file_set

Parameters:

  • file_set_params (Hash) (defaults to: {})

    specifying the visibility, lease and/or embargo of the file set. Without visibility, embargo_release_date or lease_expiration_date, visibility will be copied from the parent.

Yields:
