Problem mit dem Django -Anmeldeformular: Das Formular ist trotz korrekter Anmeldeinformationen ungültig ⇐ Python

[Anonymous]

Ich habe ein Problem mit meinem Django -Login -Formular vorgestellt. Obwohl das Formular die richtigen Anmeldeinformationen bereitstellt, kehrt das Formular konsequent als ungültig zurück. Hier ist eine detaillierte Beschreibung meines Setups und das Problem, auf das ich begegnet bin. AuthentifizierungForm zur Behandlung der Benutzeranmeldung. Mein Ziel ist es, Benutzer zu authentifizieren und nach erfolgreichem Anmeldung zu einer bestimmten Seite umzuleiten. Die Formularvalidierung schlägt jedoch fehl, obwohl die Anmeldeinformationen korrekt sind und der Benutzer in der Datenbank vorhanden ist.
from django import forms
from .models import UserRegister
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm , AuthenticationForm
from django.core.exceptions import ValidationError

class UserRegisterForm(UserCreationForm):
username = forms.CharField(max_length=50, required=True, widget=forms.TextInput(attrs={'placeholder': 'Username', 'class': 'input-group'}))
email = forms.EmailField(max_length=70, required=True, widget=forms.EmailInput(attrs={'placeholder': 'Email', 'class': 'input-group'}))
password1 = forms.CharField(max_length=128, required=True, widget=forms.PasswordInput(attrs={'placeholder': 'Password', 'class': 'input-group', 'id': 'password'}))
password2 = forms.CharField(max_length=128, required=True, widget=forms.PasswordInput(attrs={'placeholder': 'Confirm Password', 'class': 'input-group', 'id': 'password'}))

class Meta:
model = UserRegister
fields = ['username', 'email', 'password1', 'password2']
error_messages = {
"password_mismatch": "Conform Password Does not match with Password"
}

def clean_email(self):
email = self.cleaned_data.get('email')

raise ValidationError('This email address is already in use.')
return email

return password2
