Question

我正在这样做tutorial。不幸的是，它适用于其他版本的Django（我使用的是最新版本）。我发现了一个错误404的小问题，但我不知道如何解决。我正在寻求帮助来解决它。

启动页面“ http://127.0.0.1:8000/reviews/”时出错：

Using the URLconf defined in winerama.urls, Django tried these URL patterns, in this order:

^$ [name='review_list']
^review/(?P<review_id>[0-9]+)/$ [name='review_detail']
^wine$ [name='wine_list']
^wine/(?P<wine_id>[0-9]+)/$ [name='wine_detail']
admin/
The current path, reviews/, didn't match any of these.

我的views.py（应用程序）

from django.shortcuts import get_object_or_404, render
from .models import Review, Wine

def review_list(request):
    latest_review_list = Review.objects.order_by('-pub_date')[:9]
    context = {'latest_review_list':latest_review_list}
    return render(request, 'reviews/review_list.html', context)

def review_detail(request, review_id):
    review = get_object_or_404(Review, pk=review_id)
    return render(request, 'reviews/review_detail.html', {'review': review})

def wine_list(request):
    wine_list = Wine.objects.order_by('-name')
    context = {'wine_list':wine_list}
    return render(request, 'reviews/wine_list.html', context)

def wine_detail(request, wine_id):
    wine = get_object_or_404(Wine, pk=wine_id)
    return render(request, 'reviews/wine_detail.html', {'wine': wine})

我的urls.py（应用程序）

from django.conf.urls import url

from . import views

app_name = 'reviews'

urlpatterns = [
    # ex: /
    url(r'^$', views.review_list, name='review_list'),
    # ex: /review/5/
    url(r'^review/(?P<review_id>[0-9]+)/$', views.review_detail, name='review_detail'),
    # ex: /wine/
    url(r'^wine$', views.wine_list, name='wine_list'),
    # ex: /wine/5/
    url(r'^wine/(?P<wine_id>[0-9]+)/$', views.wine_detail, name='wine_detail'),
]

我的urls.py

from django.contrib import admin
from django.urls import path, include

app_name = 'reviews'

urlpatterns = [
    path('', include('reviews.urls', namespace="reviews")),
    path('admin/', admin.site.urls),
]

如何正确更正代码。我了解该错误位于urls.py（应用程序）中。任何帮助将不胜感激。

我认为您可以在“ http://127.0.0.1:8000/”上看到评论。

如果您想在'http://127.0.0.1:8000/reviews'看到review_list，则可以尝试一下。

from django.contrib import admin
from django.urls import path, include, url

app_name = 'reviews'

urlpatterns = [
    # path('', include('reviews.urls', namespace="reviews")),
    # path('admin/', admin.site.urls),
    url(r'^reviews/', include('reviews.urls', namespace="reviews")),
    url(r'^admin/', include(admin.site.urls)),
]

找不到页面（404）Django。定义网址
