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: resources_index.rb
    path of file: ./repos/Faalis/lib/faalis/dashboard/sections
    
    the code of the file until where you have to start completion: require_dependency 'faalis/dashboard/dsl/index'

module Faalis::Dashboard::Sections
  module ResourcesIndex

    extend ActiveSupport::Concern

    # The actual action method of a dashboard controller
    def index
      authorize model
      fetch_and_set_all
      action_buttons(index_properties)

      @_tools_
    
    def fetch_index_objects
      scope = index_properties.default_scope
      puts "<<<<<<<" * 100, scope
      if !scope.nil?

          # If user provided an scope for `index` section.

          if scope.respond_to? :call
            # If scope provided by a block
            scope = scope.call
          else
            # If scope provided by a symbol
            # which should be a method name
            scope = self.send(scope)
          end
