简单留言簿 django:__ init__()有1个位置参数，但给出了2个

我刚刚接触 Django，正在尝试编写一个简单的留言簿应用程序来适应环境。我得到下面的错误，但我不能找到错误:

异常值: _ Init _ ()有1个位置参数，但给出了2个。

from django.db import models
from django.contrib.auth.models import User
from django.contrib import admin


class Bericht(models.Model):
titel = models.CharField(max_length=50)
auteur = models.ForeignKey(User, blank=True)
email = models.EmailField(max_length=75)
inhoud = models.TextField(max_length=10000, blank=True)
datum = models.DateTimeField(auto_now_add=True)


def __str__(self):
return str(self.auteur) + " : " + str(self.titel)


class Meta:
verbose_name_plural = "berichten"


class BerichtAdmin(admin.ModelAdmin):
list_display = ["auteur", "datum", "titel"]
list_filter = ["datum", "auteur"]


admin.site.register(Bericht, BerichtAdmin)

from django.shortcuts import render
from django.views.generic import ListView
from Gastenboek.models import *


class BerichtListView(ListView):
model = Bericht.objects.all()
template_name = 'template/bericht_lijst.html'
paginate_by = 10
context_object_name = "bericht_lijst"
# Create your views here.
