сообщение об ошибке: неопределенный метод `create 'для # Вы имели в виду? создано на. Попытка использовать шаблон дизайна политики

Я пытаюсь использовать шаблон разработки политики, но не могу заставить его работать. Это говорит о том, что мой метод создания не определен, но не могу понять, почему. Пожалуйста, помогите: это мой файл политики: 

class GymClassPolicy < ApplicationPolicy
    attr_reader :user, :gym_class  
    def initialize(user, gym_class)
      @user = user
      @gym_class = gym_class
    end

    def create?
      user.admin?
    end


  end

Это мой контроллер. Я пытаюсь использовать шаблон разработки политики в методе создания 

require 'observer'
require './app/policies/gym_class_policy'


class GymClassesController < ApplicationController
  include Observable
  before_action :set_gym_class, only: [:show, :edit, :update, :destroy]

  # GET /gym_classes
  # GET /gym_classes.json
  def index
    @gym_classes = GymClass.all

  end




  # GET /gym_classes/1
  # GET /gym_classes/1.json
  def show
  end

  # GET /gym_classes/new
  def new
    @gym_class = GymClass.new

  end


  # GET /gym_classes/1/edit
  def edit
  end
  def gym_class_policy
    @_gym_class_policy ||= GymClassPolicy.new(gym_class)
  end 

  # POST /gym_classes
  # POST /gym_classes.json
  def create
    @gym_class = GymClass.new(gym_class_params)
    authorize @gym_class
    if @gym_class.create(gym_class_params)
      redirect_to @post
    else
      render :edit
    end



    respond_to do |format|
      if @gym_class.save
        format.html { redirect_to @gym_class, notice: 'Gym class was successfully created.' }
        format.json { render :show, status: :created, location: @gym_class }
      else
        format.html { render :new }
        format.json { render json: @gym_class.errors, status: :unprocessable_entity }
      end
    end




  end

  def update
    respond_to do |format|
      if @gym_class.update(gym_class_params)
        format.html { redirect_to @gym_class, notice: 'Gym class was successfully updated.' }
        format.json { render :show, status: :ok, location: @gym_class }

      else
        format.html { render :edit }
        format.json { render json: @gym_class.errors, status: :unprocessable_entity }
      end
    end
  end


  # DELETE /gym_classes/1
  # DELETE /gym_classes/1.json
  def destroy
    @gym_class.destroy
    respond_to do |format|
      format.html { redirect_to gym_classes_url, notice: 'Gym class was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_gym_class
      @gym_class = GymClass.find(params[:id])
    end

    # Only allow a list of trusted parameters through.
    def gym_class_params
      params.require(:gym_class).permit(:Type, :PTName, :Date, :Time)
    end
    def Time=(new_Time)
      @Time = new_Time

Измените create на save в app / controllers / gym_classes_controller.rb: 43 

@gym_class = GymClass.new(gym_class_params)
authorize @gym_class
if @gym_class.save(gym_class_params)
  redirect_to @post
