Question

我正在尝试建立一个到管理页面（localhost:8000/admin）的链接，但是当尝试这样链接时： HTML：

{% if user.is_staff %}
  <a class="nav-item nav-link" href="{% url 'admin' %}">Admin</a>
{% endif %}

代码：

urlpatterns = [
  path('admin/', admin.site.urls, name='admin'),
]

我收到一个错误，说NoReverseMatch at /。

跟踪：

为什么会这样？它可以与其他链接一起使用，但不适用于管理员。

Python 3.7.3
Django 2.3

Django网址错误。调试返回NoReverseMatch
