▶ def review_delete(request, restaurant_id, review_id) : url path parameter로 restaurant_id와 review_id를 넘겨줌

▶ return redirect('restaurant-detail', id=restaurant_id) : detail 화면으로 돌아감

 

 

from django.urls import path
from . import views

urlpatterns = [
    path('list/', views.list, name="list"),
    path('create/', views.create, name="restaurant-create"),
    path('update/', views.update, name="restaurant-update"),
    # path('detail/', views.detail, name="restaurant-detail"),

    path('restaurant/<int:restaurant_id>/review/delete/<int:review_id>', views.review_delete, name="review-delete")
]

▶ urls.py에 review_delete 화면 경로를 추가

▶ bootstrap을 이용해서 디자인 수정 및 리뷰 삭제 버튼 추가
