Ruby on rails 运行CURL命令创建新位置后，获得422个不可处理的实体

我有一个小问题，那就是我的“创建新地方”计划没有通过

这是我的curl命令：

curl -H 'Content-Type: application/json' -X POST -d '{"place": {"name": "the stroke", "address": "the stroke YOLO", "description":"YOLOOOOO", "phone":"9128911", "website":"www.thestrokes.com"}}' http://localhost:3000/api/v1/places
-i -H 'Authorization: Token token="8f8315d4892044479450ef3403c0af95"'

这是我的地方：

 module Api 
    module V1
        class PlacesController < Api::ApiController  # Api::BaseController
            respond_to :json
         before_action :authenticate #This authenticate method inherit from Api Controller
         skip_before_action :verify_authenticity_token


         def index
            respond_with @user.places
         end

         def show
            respond_with Place.find(params[:id])
         end

         def create
            respond_with Place.create(params[:product])
         end

         def update
            respond_with Place.update(params[:id], params[:products])
         end

         def destroy
            respond_with Place.destroy(params[:id])
         end

            # private

            # def authenticate
            #   authenticate_or_request_with_http_token do |token, options|
            #   current_user.find_by(access_token: token)
            # end

            # end
        end
    end
end

希望有人能帮我解决这个问题
