为什么我在模板中使用 href="{{ panel.get_absolute.url }}" 时会出现错误？

我编写了一个简单的页面来显示商品列表，当您单击每个商品时，它会将您转发到目的页面以显示商品的详细信息，但我认为这种方法现在不起作用或者我犯了一个错误......

这是我的模型：

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse

class PanelManager(models.Manager):
    def ye(self,year):
        return self.filter(publish__year=year)
    def pu(self,publish):
        return self.filter(status=publish)

class PublishedManager(models.Manager):
    def get_queryset(self):
        return super(PublishedManager,self).get_queryset().filter(status='published')



class Panel(models.Model):
    STATUS_CHOICES = (
        ('draft', 'Draft'),
        ('published', 'Published'),
    )
    title = models.CharField(max_length=250)
    slug = models.SlugField(max_length=250, unique_for_date='publish')
    body = models.TextField()
    publish = models.DateTimeField(default=timezone.now)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    status = models.CharField(max_length=10, choices=STATUS_CHOICES, default='draft')
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    objects = PanelManager()
    published = PublishedManager()
    # objects = models.Manager()

    def get_absolute_url(self):
        return reverse('users:details',args=[self.slug, self.id])

    class Meta:
        ordering = ('-publish',)
    def __str__(self):
        return self.title

我的观点：

from django.shortcuts import render,get_object_or_404
from django.http import HttpResponse
from .models import Panel


def test1(request):
    return HttpResponse("Hello this is test1")

def panellist(request):
    panels=Panel.objects.filter(publish__year=2024)
    return render(request, 'users/panel/panel list.html',{'panels':panels})

def p_details(request,panel, pk):
    panel=get_object_or_404(Panel,slug=panel,id=pk)
    return render(request, 'users/panel/details.html', {'panel':panel})

我的网址：

from django.urls import path
from .import views

urlpatterns = [
    path('panellist/', views.panellist, name='panellist'),
    path('details/<slug:panel>/<int:pk>/', views.p_details, name='details'),

]

我的模板


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>test 2</title>
</head>
<body>
<h1>second test</h1>
{% for panel in panels %}
    <a href="{{ panel.get_absolute_url }}">
        <h2>{{panel.title}} : {{panel.author}}   -   {{panel.status}}</h2>
    </a>

{% endfor %}
</body>
</html>

应用程序已安装：

我的面板字段：
在此处输入图像描述

然后我收到这个错误：

模板渲染时出错

在模板中，第10D:\Shahram\projects\New folder 4\D_newsite\templates\users\panel\panel list.html行出现错误

“用户”不是注册的命名空间

10 <a href="{{ panel.get_absolute_url }}">

    这是问题所在：

    def get_absolute_url(self):
    return reverse('users:details',args=[self.slug, self.id])

    该错误告诉您它不知道users:该 url 名称中的前缀。

    您的urls.py文件包含一个名为 的 URL details，但不包含users:details。
