NoReverseMatch 在 /app/index 我已经 URL

Question

我在 /app/index 处遇到错误，NoReverseMatch。 我在views.py中写了

def index(request):
    return render(request, 'index.html')

def test1(request):
    return render(request, 'test1.html')

def test2(request):
    return render(request, 'test2.html')

在 urls.py 中

app_name = "app"
urlpatterns = [
    path('index', views.index,name='index'),
    path('test1', views.test1,name='test1'),
    path('test2', views.test2,name='test2'),
]

在 index.html 中

    <tr>

        <td align="center ">
            <a class="test1" href="{% url 'test1' %} ">test1</a>
        </td>

        <td align="center ">
            <a class="test2" href="{% url 'test2' %} ">test2</a>
        </td>
    </tr>

当我访问索引方法时， /app/index 处的 NoReverseMatch 未找到“test1”的反向。 “test1”不是有效的视图函数或模式名称。发生错误。 我重写了

<a class="test1" href="{% url 'app:test1' %} ">test1</a>

但同样的错误发生了。 我真的不明白为什么会出现这个错误。我已经 test1&test2 url。我应该如何解决这个问题？ 追溯 说 Traceback（最近一次调用最后一次）：

我的基本网址是

from django.conf import settings
from django.conf.urls import include, url
from django.conf.urls.static import static
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    url('admin/', admin.site.urls),
    url('app/', include('app.urls')),

 ]

Answer 1

你可以试试这个， 在views.py

def index(request):
    return render(request, 'app/index.html')

def test1(request):
    return render(request, 'app/test1.html')

def test2(request):
    return render(request, 'app/test2.html')

Answer 2

我不确定，但值得尝试更改您在 django.urls docs 上显示的导入和 urlpatterns：

from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),  # note that its `path` not `url`
    path('app/', include('app.urls')),  # note that its `path` not `url`
]
