Django应用未加载并显示IsADirectoryError错误

如何解决Django应用未加载并显示IsADirectoryError错误

我是django和python的新手。我使用django主题来构建网站。 Djanog，Nginx，Gunicorn运行正常。问题是当我尝试使用应用程序URL加载页面时，它给了我IsADirectoryError。以下是所有信息。

基本目录

drwxr-xr-x 6 rwb  root 4096 Jul 30 15:43 netdash_venv/
drwxr-xr-x 3 rwb  root 4096 Aug  5 16:12 projects/core

netdash_venv 是python虚拟文件夹，所有项目文件都位于 projects 下的 core 文件夹中。

:/opt/netdash/projects$ ll core
total 76
drwxrwxr-x 7 rwb rwb       4096 Aug 11 11:28 ./
drwxr-xr-x 3 rwb root      4096 Aug  5 16:12 ../
drwxrwxr-x 4 rwb rwb       4096 Aug 10 16:30 app/
drwxrwxr-x 4 rwb rwb       4096 Aug  5 16:31 authentication/
drwxrwxr-x 5 rwb rwb       4096 Aug  5 16:17 core/
srwxrwxrwx 1 rwb www-data     0 Aug 11 11:28 core.sock=
-rw-r--r-- 1 rwb rwb      40960 Aug  5 16:39 db.sqlite3
-rwxr-xr-x 1 rwb rwb        624 Aug  5 15:36 manage.py*
drwxrwxr-x 4 rwb rwb       4096 Aug 10 16:00 sei/
drwxrwxr-x 4 rwb rwb       4096 Aug  5 15:48 staticfiles/

应用和身份验证应用处理身份验证/登录/注销部分。我从侧边栏网址启动sei应用程序时遇到问题。

sidebar.html 文件位于 projects / core / core / templates / 文件夹中。

        <li class="nav-item">
          <a class="sidebar-link" href="/sei">
            <span class="icon-holder">
              <i class="c-red-500 ti-video-camera"></i>
            </span>
            <span class="title">SEI</span>
          </a>
        </li>

当我单击上方的href链接时，出现以下错误。

from django.shortcuts import render,get_object_or_404,redirect
from django.template import loader
from django.http import HttpResponse
from django import template

# Create your views here.

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

@login_required(login_url="/login/")
def pages(request):
    context = {}
    # All resource paths end in .html.
    # Pick out the html file name from the url. And load that template.
    load_template = request.path.split('/')[-1]
    html_template = loader.get_template( load_template )
    return HttpResponse(html_template.render(context,request))

sei-urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('',name="sei"),]

sei-views.py

from django.shortcuts import render
from .models import camera

# Create your views here.
def index(request):

    cameras = camera.objects.all()

    return render(request,"sei.html",{'cameras': cameras})

我尝试了多种方法。我可以登录和注销，但是每当我尝试转到/ sei时，都会出现错误。请帮忙。

解决方法

Django按照输入的顺序对照urlpatterns列表检查url。

您当前的核心-urls.py 如下：

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

urlpatterns = [
    path('admin/',admin.site.urls),# Django admin route 
    path("",include("authentication.urls")),# Auth routes - login / register
    path("",include("app.urls")),# UI Kits Html files
    path("sei/",include("sei.urls")),]

这意味着将在 sei.urls 之前检查 app.urls 。

我不是正则表达式专家，但“ sei /”似乎与应用中页面视图的网址匹配。然后，它尝试加载 sei 作为模板，但由于是目录...“ / sei /中的IsADirectoryError”而无法加载。

您可以通过将正则表达式替换为 r'^ / [^ /] *。html'来改进正则表达式，以便仅匹配指向根文件夹并以 .html

我建议重新排列您的网址，以便首先检查更具体的网址。

新核心-urls.py

from django.contrib import admin
from django.urls import path,# Django admin route 
    path("sei/",path("",# UI Kits Html files
]

通过这种方式， sei / 将首先匹配并加载正确的视图。
