【问题描述】：

django 正在将 /static/ url 添加到我的路径中，我不知道为什么

找不到页面 (404) 请求方法：GET 请求 URL：http://localhost:8000/static/feed.html 'feed.html' 无法找到了
找不到页面 (404) 请求方法：GET 请求 URL：http://localhost:8000/static/messages.html'messages.html' 可以找不到
找不到页面 (404) 请求方法：GET 请求 URL：http://localhost:8000/static/upload.html'upload.html' 不能被发现

这是我的意见.py

from django.shortcuts import render
from django.views.generic import TemplateView, ListView, CreateView
from app.models import SendSMS
from app.forms import SendSMSForm
from django.urls import reverse_lazy
from app.utils import send_twilio_message
from django.conf import settings 
import datetime
# Create your views here.

# Create your models here.

def index(request): 
     return render(request, 'index.html')
def feed(request): 
     return render(request, 'feed.html')
def upload(request): 
     return render(request, 'upload.html')
def messages(request): 
    return render(request, 'messages.html')
def statistics(request): 
    return render(request, 'statistics.html')


class SendSmsCreateView(CreateView):
     model = SendSMS
     form_class = SendSMSForm
     template_name = 'messages.html'
     success_url = reverse_lazy('send_sms')

     def form_valid(self, form):
         number = form.cleaned_data['to_number']
         body = form.cleaned_data['body']
        # call twilio
         sent = send_twilio_message(number, body)
        # save form
        send_sms = form.save(commit=False)
        send_sms.from_number = settings.TWILIO_PHONE_NUMBER
        send_sms.sms_sid = sent.sid
        send_sms.account_sid = sent.account_sid
        send_sms.status = sent.status
        send_sms.sent_at = datetime.datetime.now()
        if sent.price:
            send_sms.price_unit = sent.price_unit
            send_sms.save()

        return super(SendSmsCreateView, self).form_valid(form)

这是我的应用程序 urls.py

from . import views
from django.contrib import admin
from django.conf.urls import url
from django.urls import path, include
app_name = 'app'

urlpatterns = [
   path('', views.index, name='index'),
   path('', views.feed, name='feed'),
   path('', views.upload, name='upload'),
   path('', views.messages, name='messages'),
   path('', views.statistics, name='statistics'),
]

这是我的项目 urls.py

from django.contrib import admin
from django.conf.urls import url
from django.urls import path, include
from app.views import SendSmsCreateView
url(r'^admin/', admin.site.urls),
# ... your url patterns
path('', include('app.urls', namespace='app')),


url(
    regex=r'^app/$',
    view=SendSmsCreateView.as_view(),
    name='send_sms'
  ),

]

这是我的 index.html 文件

{% load static %}

<!DOCTYPE html>
 <html>
<head>
</head>
<body>
<li class="nav-item">
        <a href=" {% static 'feed.html' %} " class="nav-link">
          <i class="nav-icon fas fa-th"></i>
          <p>
            Feed
            <span class="right badge badge-danger">New</span>
          </p>
        </a>
      </li>
      <li class="nav-item has-treeview">
        <a href=" {% static 'messages.html' %} " class="nav-link">
          <i class="nav-icon fas fa-copy"></i>
          <p>
            Compose Message

          </p>
        </a>

      </li>
      <li class="nav-item has-treeview">
        <a href=" {% static 'upoad.html' %} " class="nav-link">
          <i class="nav-icon fas fa-chart-pie"></i>
          <p>
            Upload CSV
          </p>
        </a>
      </li>

   </body>

【解决方案1】：

一些注意到的故障是

视图中缺少上下文，如图所示添加一个空括号，它现在将作为上下文服务，稍后您可以添加所需的键和值

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

索引网址错误，需要添加非重叠正则表达式模式

path('', views.index, name='index'),
path('feed/', views.feed, name='feed'),
path('upload/', views.upload, name='upload'),
path('messages/', views.messages, name='messages'),
path('statistics/', views.statistics, name='statistics'),

将网址更改为已过时的路径

path('app/',
    view=SendSmsCreateView.as_view(),
    name='send_sms'
  ),

【解决方案2】：

我所做的是在 html 文件中添加命名空间

在我使用之前

 <a href=" {% url 'feed.html' %} " class="nav-link active">

上面的没有用，所以我把它改成了

 <a href=" {% url 'app:feed' %} " class="nav-link active">
