How do create url to django Admin within my user page (HTML) - django

Question

I'm new to coding, I'm trying to create URL link in NavBar to redirect my Django Admin exmple:
<a class="nav-link" href="{% url 'admin'%}"> Admin site </a>
However, Django do find; No-Reverse-Match,
It works for other URL links
Things I had to try:
Is adding a name in project URL
including URL path in my App URL
My project URL code:
from Django.contrib import admin
from django.urls import path, include
urlpatterns = [
path(r'admin/', admin.site.urls, name='admin' ),
path(r'accounts/', include('django.contrib.auth.urls')),
path(r'api-auth/', include('rest_framework.urls'), name='rest_framework'),
path(r'', include('app.urls')),
My App URL code:
from django.urls import path, include
from . import views #function views
from django.contrib.auth.decorators import login_required, permission_required
from rest_framework import routers
router = routers.DefaultRouter()
router.register(r'tank', views.TankViewSet)
router.register(r'room', views.RoomViewSet)
# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
path(r'',login_required(views.index), name='index'),
path (r'test/',views.Test),
path(r'^Water/',login_required(views.Lquid), name='tank'),
path(r'^Ambient/',login_required(views.Ambient), name='room'),
path(r'Rest-api/', include(router.urls)),
#path(r'admin/', admin.site.urls, name='admin' ), this somthing I had try
]
Basically, Django makes in a way that works and redirect to the URL link on any page
NAVBAR:
Admin site
App URL:
path(r'',login_required(views.index), name='index'),
With this two link it will redricet to the page you set.

You need to specify the admin page you want to redirect to when doing a reverse lookup of admin. To get to the admin homepage you will want this reverse lookup
reverse('admin:index')
So to link to the admin homepage in your nav bar, it should look like this
<a class="nav-link" href="{% url 'admin:index' %}"> Admin site </a>
