URL 错误 404 找不到 Django 页面错误 x.html

Question

我还没有设法找到它给出错误的原因？ 在 StackOverflow 中复制粘贴以获得 exp 的地方收到了很多答案

所以情况是我的 navbar.html 中的 URL 返回错误 404 找不到 x.html

这里是每个 py 文件的代码：

views.py：

from django.shortcuts import render, redirect
from django.core.mail import send_mail, BadHeaderError
from django.http import HttpResponse, HttpResponseRedirect
from django.conf import settings
from .forms import ContactForm

# Create your views here.

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

def education(request):
    return render(request, 'Education.html')

def experience(request):
    return render(request, 'Experience.html')

def portfolio(request):
    return render(request, 'Portfolio.html')

setting.py：

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, '../blog_level/static')
STATICFILES_DIRS= [
    os.path.join(BASE_DIR, 'static'),
]

navbar.html：

 <ul class="u-align-center u-nav u-popupmenu-items u-unstyled u-nav-2"><li class="u-nav-item"><a class="u-button-style u-nav-link" href="{% url 'homepage' %}" style="padding: 10px 0px; text-shadow: 0 0 8px rgba(128,128,128,1);">Home</a>
</li><li class="u-nav-item"><a class="u-button-style u-nav-link" href="{% url 'experience' %}" style="padding: 10px 0px; text-shadow: 0 0 8px rgba(128,128,128,1);">Experience</a>
</li><li class="u-nav-item"><a class="u-button-style u-nav-link" href="{% url 'education' %}" style="padding: 10px 0px; text-shadow: 0 0 8px rgba(128,128,128,1);">Study</a>
</li><li class="u-nav-item"><a class="u-button-style u-nav-link" href="{% url 'portfolio' %}" style="padding: 10px 0px; text-shadow: 0 0 8px rgba(128,128,128,1);">Portfolio</a>
</li><li class="u-nav-item"><a class="u-button-style u-nav-link" href="{% url 'homepage' %}#sec-1120" data-page-id="134427998" style="padding: 10px 0px; text-shadow: 0 0 8px rgba(128,128,128,1);">Contact</a>
</li></ul>

blog_level\urls.py：

from django.contrib import admin
from django.urls import path, re_path
from . import views

urlpatterns = [
    path('', views.home_page, name='homepage'),
    path('education/', views.education, name='education'),
    path('experience/', views.experience, name='experience'),
    path('portfolio/', views.portfolio, name='portfolio'),
]

fist_website_app_level.py：

"""first_website_app_level URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/3.2/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('', include('blog_level.urls')),

请找出调试错误：

我还是不明白这个过程的错误为什么它不会链接到正确的页面，自然是基于以下专家在一个简单的项目级别。

Answer 1

您的网址错误： 而不是：

127.0.0.1:8000/Experience.html

使用：

127.0.0.1:8000/experience

因为您的视图中有“经验”：path('experience', ...)

Answer 2

在Django urls.py 是在views 和url 之间映射的文件，所以如果你想访问Experience.html 页面，你必须将url 设置为127.0.0.1:8000/experience（什么都没有要更改代码，只需更新您在浏览器中使用的 URL），因为 urls.py 的映射为 path('experience/', views.experience, name='experience'),

Here 是一个很好的文档，介绍了 url 映射的工作原理。
