Defined in:
app/presenters/hyrax/pcdm_member_presenter_factory.rb

Overview

constructs presenters for the pcdm:members of an Object, omitting those not readable by a provided Ability.

this implementation builds the presenters without recourse to the request context and ActiveFedora-specific index structures (i.e. no ‘list_source` or `proxy_in_ssi`).

def file_set_presenters
  return enum_for(:file_set_presenters).to_a unless block_given?

  results = query_docs(generic_type: "FileSet")

  object.member_ids.each do |id|
    id = id.to_s
    indx = results.index { |doc| id == doc['id'] }
    next if indx.nil?
    hash = results.delete_at(indx)
    yield presenter_for(document: ::SolrDocument.new(hash), ability: ability)
  end
end

#member_presenters ⇒ Array<FileSetPresenter, WorkShowPresenter> #member_presenters ⇒ Array<FileSetPresenter, WorkShowPresenter>

Note:

defaults to using ‘object.member_ids`. passing a specific set of ids is supported for compatibility with MemberPresenterFactory, but we recommend making sparing use of this feature.
