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: fixture_creator.rb
    path of file: ./repos/magic_lamp/lib/magic_lamp
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module MagicLamp
  class FixtureCreator
    include Callbacks

    attr_accessor :render_arguments

    def generate_template(controller_class, extensions,
    
    def redefine_view_context(controller, extensions)
      controller.singleton_class.send(:define_method, :view_context) do |*args, &block|
        view_context = super(*args, &block)
        extensions.each { |extension| view_context.extend(extension) }
        view_context
      end
    end
