    Metadata details:
    filename: editorable.rb
    path of file: ./repos/bluedoc/app/models/concerns
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Editorable
  def edito
    
  def add_editor(editor_id)
    return if editor_id.blank?

    if editor_id.is_a?(Array)
      self.editor_ids += editor_id
    else
      self.editor_ids << editor_id
    end
