from fcuser.views import index, RegisterView, LoginView
from product.views import ProductList, ProductCreate, ProductDetail
from order.views import OrderCreate, OrderList
 
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', index),
    path('register/', RegisterView.as_view()), #클래스는 .as_view() 를 해주어야 함
    path('login/', LoginView.as_view()),
    path('product/', ProductList.as_view()),
    path('product/<int:pk>/', ProductDetail.as_view()),
    path('product/create/', ProductCreate.as_view()),
    path('order/', OrderList.as_view()),
    path('order/create/', OrderCreate.as_view()),
]
 

from order.views import OrderCreate, OrderList

 

 path('order/', OrderList.as_view()),

 path('order/create/', OrderCreate.as_view()), 

를 추가해주세요

 

확인하기

이제 터미널에서 python manage.py runserver 을 해서 서버를 열고

127.0.0.1:8000/product/로 가시면 아래와 같이 상품 목록이 나올거에요 화면이 나올거에요

 

이 상태에서 상품을 눌러보시면

이렇게 주문하기가 나올겁니다. 그럼 수량을 적고 주문하기를 눌러보세요 

 

주문하기 눌르면 목록으로 url 화면이 바뀔겁니다. 

 

그리고 주문했던 상품을 들어가보시면 수량이 줄어든걸 확인하실수 있구요

 

127.0.0.1:8000/order 주소로 들어가보시면 주문했던걸 확인하실수 있으실거에요

 

 

그럼 20000~~
