"uninitialized constant Api::V1::ReservationOptionsController::ReservationOptions"

Question

我正在尝试创建 API，但出现错误

"type": "NameError",
"message": "uninitialized constant Api::V1::ReservationOptionsController::ReservationOptions",

我在这里似乎找不到问题。

代码

路线

namespace :api, defaults: { format: :json } do
    namespace :v1 do
      resources :reservation_options, only: [:show, :create]
    end
end

controllers/api/v1/reservation_options_controller.rb

class Api::V1::ReservationOptionsController < Api::V1::BaseController
  acts_as_token_authentication_handler_for User, only: [:create]

  def show
    @reservation_option = ReservationOption.find(params[:id])
    @reservation = @reservation_option.reservation
    authorize @reservation_option
  end

  def create
    @user = current_user
    @reservation_option = ReservationOptions.new(reservation_option_params)
    authorize @reservation_option
    if @reservation_option.save
      render :show, status: :created
    else
      render_error
    end
  end

  private
  def reservation_option_params
    params.require(:reservation_option).permit(:option_id, :option_quantity, :reservation_id)
  end
end

Answer 1

好像 ReservationOptions 没有在任何地方定义，你在 controllers/api/v1/reservation_options_controller.rb 中使用它。

确保您拼写正确，或者您在 app/models/reservation_option.rb 中有合适的模型。我的猜测是它应该是 ReservationOption，因为 Rails 模型 class 名称通常是单数。

Answer 2

您在创建操作时出错

def create
    @user = current_user
    # change this line
    # @reservation_option = ReservationOptions.new(reservation_option_params)
    @reservation_option = ReservationOption.new(reservation_option_params)
    authorize @reservation_option
    if @reservation_option.save
      render :show, status: :created
    else
      render_error
    end
  end
