我正在做一个django项目，每当我运行“python manage.py runserver”时，我看到上面的错误。
views.py

from django.shortcuts import render
from django.http import HttpResponse
from .models import ToDoList, Item

# Create your views here.

def index(response, id):
    ls = ToDoList.objects.get(id=id)
    return render(response, "main/base.html", {})

def home(response):
    return render(response, "main/home.html", {})

url.py

from django.urls import path
from main import views
from . import views

urlpatterns = [
path("<int:id>", views.index, name="index"),
path("", views.home, name="home")
]

我的网站url.py

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include("main.urls")),
]

谢谢你的帮助。
