You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: tree_entry_presenter.rb
    path of file: ./repos/gitlabhq/app/presenters
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class TreeEntryPresenter < Gitlab::View::Presenter::Delegated
  presents nil, as: :tree

 
    
  def ref_qualified_path
    # If `ref_type` is present the commit_id will include the ref qualifier e.g. `refs/heads/`.
    # We only accept/return unqualified refs so we need to remove the qualifier from the `commit_id`.

    commit_id = ExtractsRef::RefExtractor.unqualify_ref(tree.commit_id, ref_type)

    File.join(commit_id, tree.path)
  end
