Python Django - change_view() 缺少 1 个必需的位置参数：'object_id'

Question

I am new in Django Framework and currently working on first project. I made a simple contact form it takes data from users and save it into database. Everything is working right. But when I login into my admin panel and go into the Contacts and click on the data that I received. I am getting error "change_view() missing 1 required positional argument: 'object_id'".

my admin.py

from home.views import contact
from django.contrib import admin
from home.models import Contact

# Register your models here.
admin.site.register(Contact)

my models.py

from django.db import models

# Create your models here.
class Contact(models.Model):
    name = models.CharField(max_length=30)
    email = models.EmailField()
    phone = models.CharField(max_length=10)
    desc = models.TextField()

my views.py

from home.models import Contact
from django.shortcuts import render, HttpResponse
from home.models import models

# Create your views here.
def home(request):
    return render(request, 'home.html')

def about(request):
    return render(request, 'about.html')
    

def projects(request):
    return render(request, 'projects.html')

def contact(request):
    if request.method=='POST':
        print('This is POST')
        name = request.POST['name']
        email = request.POST['email']
        phone = request.POST['phone']
        desc = request.POST['desc']
        # print(name, email, phone, desc)
        contact = Contact(name=name, email=email, phone=phone, desc=desc)
        contact.save()
        print('DAta has been written into the Database')
    # return HttpResponse("This is My Contact")
    return render(request, 'contact.html')
