Ich bin neu in Django und versuche, eine einfache Gästebuchanwendung zu erstellen, um mich an die Umgebung zu gewöhnen. Ich erhalte den folgenden Fehler, kann den Fehler jedoch nicht finden:
Ausnahmewert: _ init _ () akzeptiert 1 Positionsargument, aber 2 wurden angegeben.
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)

Antworten:
In Ihrer urls.py:
Sie vermissen .as_view ()
ändere es in:
(r"^(\d+)/$", Gastenboek.views.BerichtListView.as_view()), (r"", Gastenboek.views.BerichtListView.as_view()),
