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: kaminari.rb
    path of file: ./repos/vglist/sorbet/tapioca/compilers
    
    the code of the file until where you have to start completion: # typed: true

module Tapioca
  module Compilers
    class Kaminari < Tapioca::Dsl::Compiler
      extend T::Sig

      ConstantType = type_member { { fixed: T.class_of(::ActiveRecord::Base
    
      def decorate
        # Get the configured Kaminari page method name, or fall back to 'page' if necessary.
        page_method = T.unsafe(::Kaminari).config.page_method_name || 'page'

        root.create_path(constant) do |klass|
          klass.create_module('GeneratedRelationMethods').create_method(
            page_method.to_s,
            parameters: [create_opt_param('num', type: 'T.nilable(Integer)', default: 'nil')],
            return_type: 'PrivateRelation'
          )
        end
      end
