我正在尝试开发带有Django 2.1.3和python 3.7.1的网站，当我转到主页时出现此错误：

/ init （）处的TypeError接受1个位置参数，但给出了2个

以下是有关我编写的代码的一些详细信息：

core / models.py

这只是DB上的一张表：

from django.db import models


class Evento(models.Model):
    titolo_evento = models.CharField(max_length=30)
    data_inizio = models.DateTimeField()
    data_fine = models.DateTimeField()

    def __str__(self):
        return self.titolo_evento

    class Meta:
        verbose_name = 'Evento'
        verbose_name_plural = 'Eventi'

核心/views.py

在这里，我只想通过用户身份验证即可在主页上看到数据库“ Eventi”，我认为错误在这里，但是我不知道在哪里：

from django.contrib.auth.decorators import login_required
from .models import Evento
from django.views.generic.list import ListView


@login_required
class HomeView(ListView):
    queryset = Evento.objects.all()
    template_name = 'core/homepage.html'
    context_object_name = 'lista_eventi'

核心/ urls.py

from django.urls import path
from . import views


urlpatterns = [
    path('', views.HomeView, name='homepage'),
    ]

urls.py（项目）

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

    urlpatterns = [
        path('admin/', admin.site.urls),
        path('', include('core.urls')),
        path('accounts/', include('django.contrib.auth.urls'))
    ]
