Django - Python - URL 与这些都不匹配

Question

当我写这样的代码时，在about/ 的末尾没有.html：

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index, name='index'),
    path('about/', views.about, name='about'),
    path('contact/', views.contact, name='contact'),
    path('categories/', views.categories, name='categories'),
    path('docAdd/', views.docAdd, name='docAdd')
]

在我的网页导航栏中单击 about 时出现错误，这种情况下的错误是：

" 当前路径 about.html 与其中任何一个都不匹配。"但是，当我将 about/ 更改为 about.html/ 时，我可以在导航栏中单击 about 并打开页面，但是当我在导航栏中从 about 切换到 contact 时，出现如下错误：“当前路径，about.html/contact.html ，与这些都不匹配。”

这是带有.html后缀的代码：

from django.urls import path
    from . import views

    urlpatterns = [
        path('', views.index, name='index'),
        path('about.html/', views.about, name='about'),
        path('contact.html/', views.contact, name='contact'),
        path('categories.html/', views.categories, name='categories'),
        path('docAdd.html/', views.docAdd, name='docAdd')
    ]

views.py 代码：

from django.shortcuts import render
from . models import Document

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

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

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

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

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

这是我在导航栏中单击两次时的错误，当我在 urls.py 中有 .htmlsuffix 和 about/ 时：

Page not found (404)
Request Method: GET
Request URL:    http://localhost:8000/about.html/about.html
Using the URLconf defined in thesisProject.urls, Django tried these URL patterns, in this order:

admin/
[name='index']
about.html/ [name='about']
contact.html/ [name='contact']
categories.html/ [name='categories']
docAdd.html/ [name='docAdd']
^media/(?P<path>.*)$
The current path, about.html/about.html, didn't match any of these.

这是我在导航栏中单击一次时的错误，当我在 urls.py 中没有带有 about/ 的 .htmlsuffix 时：

Page not found (404)
Request Method: GET
Request URL:    http://localhost:8000/about.html/about.html
Using the URLconf defined in thesisProject.urls, Django tried these URL patterns, in this order:

admin/
[name='index']
about.html/ [name='about']
contact.html/ [name='contact']
categories.html/ [name='categories']
docAdd.html/ [name='docAdd']
^media/(?P<path>.*)$
The current path, about.html, didn't match any of these.

index.html 中导航栏的代码：

      <div class="collapse navbar-collapse" id="ftco-nav">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item active"><a href="index.html" class="nav-link">Home</a></li>
          <li class="nav-item"><a href="about.html" class="nav-link">About</a></li>
          <li class="nav-item"><a href="categories.html" class="nav-link">Categories</a></li>
          <li class="nav-item"><a href="docAdd.html" class="nav-link">Add New Documents</a></li>
          <li class="nav-item cta"><a href="contact.html" class="nav-link"><span>Get in touch</span></a></li>
        </ul>
      </div>
    </div>
  </nav>
  <!-- END nav -->

我似乎无法解决这个问题，请帮忙。

Answer 1

原因是在html中你可能没有在nav前面放斜杠应该是这样的

 <a href=“/about/”>

这将转到 about.html 而不是将 /about.html 添加到 url 的末尾。

所以在导航栏上应该是：

<li class="nav-item"><a href="/about/" class="nav-link">About</a></li>

将您的导航栏更改为：

      <div class="collapse navbar-collapse" id="ftco-nav">
    <ul class="navbar-nav ml-auto">
      <li class="nav-item active"><a href="/index/" class="nav-link">Home</a></li>
      <li class="nav-item"><a href="/about/" class="nav-link">About</a></li>
      <li class="nav-item"><a href="/categories/" class="nav-link">Categories</a></li>
      <li class="nav-item"><a href="/docAdd/" class="nav-link">Add New Documents</a></li>
      <li class="nav-item cta"><a href="/contact/" class="nav-link"><span>Get in touch</span></a></li>
    </ul>
  </div>
</div>

urls.py 应该是这样的：

from django.contrib import admin
from django.urls import path
from main import views
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.index, name='index'),
    path('about/', views.about, name='about'),
    path('contact/', views.contact, name='contact'),
    path('categories/', views.categories, name='categories'),
    path('docAdd/', views.docAdd, name='docAdd')
]

希望对您有所帮助，如果您不明白我所说的内容，请发表评论。

首先，您不应该在您的 urls 文件中包含 .html。

当你把你的链接放在<a>标签中时，你应该像这样使用django url-reversion template tag：

{% url 'about' %}

<li class="nav-item"><a href="{% url 'about' %}">About</a></li>

还要确保您的应用目录中有一个模板文件setup。
