简单的guestbook django: __init__()接受一个位置参数，但给出了两个位置参数

I'm new to Django and trying to make a simple guestbook application to get used to the environment. I get the following mistake, but I can't locate the error:

我是Django的新手，我正在尝试创建一个简单的guestbook应用程序来适应这个环境。我有以下错误，但是我找不到错误的地方:

Exception Value: _init_() takes 1 positional argument but 2 were given.

异常值:_init_()取1个位置参数，但给出2个位置参数。

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)

#1

In your urls.py:

在你的urls . py:

You are missing .as_view()

你是失踪.as_view()

change it to:

把它改成:

(r"^(\d+)/$", Gastenboek.views.BerichtListView.as_view()),
(r"", Gastenboek.views.BerichtListView.as_view()),
