【问题描述】：
我是 Django 新手，今天尝试使用数据库运行网站时，遇到了这个错误。 我已经在 StackOverflow 和 Django 文档上搜索了所有解决方案，但我无法修复它。
This is the problem that similar to me, but it doesn't work.
我想创建一个链接，将用户从 user.html in user 移动到 index.html inCitizen
这是我的项目结构。很抱歉，因为我无法附上图片，所以我将尝试以最简单的方式解释它。
[我的项目]
->manage.py
->公民（文件夹）
-->模板（在这个文件夹中我有citizen.html、index.html、layout.html）
-->admin.py
-->models.py
-->tests.py
-->urls.py
-->views.py
->我的项目（文件夹）
-->setting.py
-->urls.py
-->我认为不重要的东西
->用户（文件夹）
-->模板（在这个文件夹中我有 login.html、user.html、layout.html）
-->urls.py
-->views.py
-->我认为不重要的东西
如您所见，我在用户的模板文件夹中有 user.html，在公民的模板文件夹中有 index.html。
这是我的代码：
公民内部的index.html
{% extends "citizens/layout.html" %}
{% block body %}
<h1>Hệ thống quản lý XNC</h1>
<table class="table">
<thead>
<tr>
<th scope="col">Số TT</th>
<th scope="col">Họ và tên công dân</th>
<th scope="col">Giới tính</th>
<th scope="col">Số Hộ chiếu</th>
<th scope="col">Chi tiết</th>
</tr>
</thead>
<tbody>
{% for citizen in citizens %}
<tr>
<th scope="row">{{ forloop.counter }}</th>
<td>{{ citizen.name }}</td>
<td>{{ citizen.sex }}</td>
<td>{{ citizen.sID }}</td>
<td><a href="{% url 'citizen' forloop.counter %}">Truy cập</a></td>
</tr>
{% endfor %}
</tbody>
</table>
{% endblock %}
user.html 内部用户
{% extends "users/layout.html" %}
{% block body %}
<h1>Chào mừng, {{ request.user.username }}</h1>
<ul>
<li>Username: {{request.user.username }}</li>
</ul>
<a href="{% url 'citizen:citizens/' %}">Truy cập Cơ sở dữ liệu</a>
{% endblock %}
公民内部的urls.py
from django.urls import path
from . import views
urlpatterns = [
path("", views.index, name="index"),
path("<int:citizen_id>", views.citizen, name="citizen"),
#path("<int:citizen_id>/passports", views.passport, name="passports")
]
公民内部的views.py
from django.shortcuts import render
from django.http import HttpResponseBadRequest, HttpResponseRedirect, Http404
from django.urls import reverse
from .models import Citizen
# Create your views here.
def index(request):
return render(request, "citizens/index.html", {
"citizens": Citizen.objects.all()
})
def citizen(request, citizen_id):
try:
citizen = Citizen.objects.get(sID=citizen_id)
except Citizen.DoesNotExist:
raise Http404("Citizen not found")
return render(request, "citizens/citizen.html", {
"citizen": citizen,
})
我的项目中的urls.py
"""htql2 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 include, path
urlpatterns = [
path('admin/', admin.site.urls),
path('citizens/', include('citizens.urls')),
path('accounts/', include('django.contrib.auth.urls')),
path('users/', include('users.urls')),
]
用户内部的urls.py
from django.urls import path
from . import views
urlpatterns = [
path("", views.index, name="index"),
path("login", views.login_view, name="login"),
path("logout", views.logout_view, name="logout"),
]
views.py 内部用户
from django.views.decorators.csrf import csrf_exempt
from django.contrib.auth import authenticate, login, logout
from django.shortcuts import render
from django.http import HttpResponseBadRequest, HttpResponseRedirect, Http404
from django.urls import reverse
@csrf_exempt
# Create your views here.
def index(request):
if not request.user.is_authenticated:
return HttpResponseRedirect(reverse("login"))
return render(request, "users/user.html")
def login_view(request):
if request.method == "POST":
username = request.POST["username"]
password = request.POST["password"]
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return HttpResponseRedirect(reverse("index"))
else:
return render(request, "users/login.html", {
"message": "Invalid credentials."
})
else:
return render(request, "users/login.html")
def logout_view(request):
pass
user.html里面，我试过用
<a href="{% url 'citizen:citizens/' %}">Go to Database</a>
但不起作用。
谢谢。我很感激。
【问题讨论】：
-
"my_app" 仅在一 (1) 块代码中定义。为什么要包含所有其他代码块？
