Einfaches Gästebuch django: __init __() braucht 1 Positionsargument aber 2 wurden gegeben

Question

Ich bin neu in Django und versuche eine einfache Gästebuch-Anwendung zu machen, um mich an die Umgebung zu gewöhnen. Ich erhalte die folgenden Fehler gemacht, aber ich kann den Fehler nicht finden:

Exception Wert: _ init _() nimmt ein Positions Argument, aber 2 gegeben wurden.

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. 

urls.py

from django.conf.urls import patterns, include, url 

from django.contrib import admin 
admin.autodiscover() 

urlpatterns = patterns('', 
    # Examples: 
    # url(r'^$', 'Niels.views.home', name='home'), 
    # url(r'^blog/', include('blog.urls')), 

    url(r'^admin/', include(admin.site.urls)), 
    (r"^(\d+)/$", 'Gastenboek.views.BerichtListView'),

Answer 1

In Ihrem urls.py:

Sie fehlen .as_view()

Änderung es zu:

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