으로 교육을 찾을 수 없습니다. 사용자가 교육 시간을 예약 할 수있을 때 앱을 만들려고합니다. 나는 다음과 같은 오류를받을 책을 만들려고 할 때 : 나는 training_id 매개 변수를 걸립니다 나던 내가 왜이 작업을 수행 할 때 잘 모릅니다활성 레코드가 없습니다. 'id'=
class BookingsController < ApplicationController
before_action :load_training, only: [:create]
def new
@booking = Booking.new
end
def create
@booking = @training.bookings.build(booking_params)
@booking.user = current_user
if @booking.save
flash[:success] = "Book created"
redirect_to training_index_url
else
render 'new'
end
end
def index
@booking = Booking.all
end
def destroy
@booking = Booking.find_by(params[:id])
@booking.destroy
flash[:success] = "Book deleted"
redirect_to training_index_url
end

def booking_params
params.require(:booking).permit(:user_id, :training_id)
end
def load_training
@training = Training.find(params[:training_id])
end
end

이 내 예약 컨트롤러 새 책
@training을 넣고 @user를 create 메소드에 넣으면 nil을 반환합니다. 왜 그런지 알고 싶습니까?
class Booking < ApplicationRecord
belongs_to :user
belongs_to :training
default_scope -> { order(created_at: :desc) }
validates :user_id, presence: true
validates :training_id, presence: true
end

새로운 예약보기 :
어디에 내 코드는 그래서 USER_ID를 검색하고을 training_id 나던 예약 모델이 내 예약 모델입니다 실패

<%= f.submit "Confirm book", class: "btn btn-primary" %>
