URL configuration for Romyk project.

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/4.2/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
from myapp.views import index, about, icecream, services, blog, contact
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', index),
    path('index/', index),  
    path('about/', about),
    path('icecream/', icecream), 
    path('services/', services), 
    path('blog/', blog), 	
    path('contact/', contact), 	
]

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

3.利用ChatGPT產生views.py有關index的函式，產生後再微幅修訂。

    return render(request, "blog.html", locals())

4.進入後台，新增2筆輪播圖的資料

5.進入前台，查看結果
