无法使用指向另一个Django模板的url路径添加锚标签
无法使用指向另一个Django模板的url路径添加锚标签
提问于 2021-06-08 07:10:59
我正在尝试在Django中使用url添加一个锚标签，如下所示：
layout.html
{% extends "tasks/layout.html" %}
{% block body %}
<h1>Tasks</h1>
<ul>
{% for task in tasks %}
<li>{{ task }}</li>
{% endfor %}
</ul>
<a href="{% url 'tasks:add' %}">Add Tasks</a>
{% endblock %}Views.py
from django.shortcuts import render
tasks = ["foo", "bar", "baz"]
# Create your views here.
def index(request):
return render(request, "tasks/index.html", {
"tasks": tasks
})
def add(request):
return render(request, "tasks/add.html")应用程序的urls.py
from django.urls import path
from . import views
app_name = "tasks"
urlpatterns = [
path("", views.index, name="index"),
path("add", views.add, name="add")
]项目的urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('hello/', include("hello.urls")),
path('newyear/', include("newyear.urls")),
path('tasks/', include("tasks.urls"))
]然而，当我使用url方法设置href时，我一直收到以下错误，但当我硬编码路径时却没有：
Error during template rendering

9 </body>
10 </html>

在app/urls.py文件中，您提到了您的app_name标签，因此每当您编写URL重定向或html模板时都必须提及
layout.html
{% extends "tasks/layout.html" %}
{% block body %}
<h1>Tasks</h1>
<ul>
{% for task in tasks %}
<li>{{ task }}</li>
{% endfor %}
</ul>
<!--- i have made change here -->
<a href="{% url 'tasks:add' %}">Add Tasks</a>
