정의되지 않은 메소드 'total'for nil : NilClass NoMethodError in ReservationsController # checkout

Question

Im은 현재 한 컨트롤러의 매개 변수를 가져 와서 다음 컨트롤러에 추가하는 방법을 알 수 없습니다. Iv는 render과 redirect_to을 시도했는데 여전히 작동하지 않습니다.

Heres는 내 컨트롤러와 뷰 -보기의 형태는 -I 모두 체크 아웃에서 같은 reservation.id를 사용하여 컨트롤러를 만들려면 내 checkout controller 의 작용을 얻는다, 그래서 체크 아웃 컨트롤러에 reservation.total를 호출 할 수 있습니다.

컨트롤러를 만들면서 체크 아웃 컨트롤러를 통해 공유 할 수있는 방법은 무엇입니까?

오류 로그 :

NoMethodError (undefined method `total' for nil:NilClass): 
    app/controllers/reservations_controller.rb:45:in `checkout' 

예약 컨트롤러 :

def checkout 




nonce = params[:payment_method_nonce] 
result = Braintree::Transaction.sale(
    :amount => @reservation.total, 
    :payment_method_nonce => nonce, 
    :options => { 
    :submit_for_settlement => true 
    } 
) 
if result.success? 
    puts "success!: #{result.transaction.id}" 
elsif result.transaction 
    puts "Error processing transaction:" 
    puts "code: #{result.transaction.processor_response_code}" 
    puts "text: #{result.transaction.processor_response_text}" 
else 
    p result.errors 
end 


end 



def create 

#!/usr/bin/env ruby 


    reviser = Reviser.find(params[:reviser_id]) 
     @reservation = current_user.reservations.create(reservation_params) 

     if @reservation.total > 0 

      @token = Braintree::ClientToken.generate 


     elsif @reservation.total == 0 
      @reservation.update_attributes status: true 
      redirect_to @reservation.reviser.user, alert: "Writing Request Success" 


     else 
      redirect_to @reservation.reviser, alert: "Oops, something went wrong..." 
     end 




    end

post 'checkout', to: 'reservations#checkout' 
get 'checkout', to: 'reservations#checkout' 

Answer 1

체크 아웃 방법을 회원 방법으로 지정 하시겠습니까? 즉, URL에 예약 된 ID를 전달하십시오.

이렇게하면 예약을 찾을 수 있습니다. ID :

@reservation = Reservation.find(params[:id]) #so you will not get the error undefined method `total' for nil:NilClass 

나는

<%= form_tag reservation_checkout_path(@reservation) %> 
    #your fields 
<% end %>
