Django login authenticate() always returns None
0
I'm creating a custom django login view but whenever I try to login authenticate() always returns None even when I type in the right password.
I don't want django's builtin login system because it didn't work either and I can't define a SignInForm. I also tried to define AUTHENTICATION_BACKENDS = ('django.contrib.auth.backends.ModelBackend',) in my settings.py but that didn't change anything.
forms.py:
class SignInForm(forms.Form):
username = forms.CharField(error_messages={"required": "Bitte fülle dieses Feld aus.", "invalid": "Dieser Wert ist ungültig."}, min_length=3, max_length=31, required=True, widget=forms.TextInput(attrs={
"placeholder": "Benutzername oder E-Mail-Adresse", #Username or e-mail
"id": "username",
"class": "select selected"
}))
password = forms.CharField(error_messages={"required": "Bitte fülle dieses Feld aus.", "invalid": "Dieses Passwort ist ungültig."}, min_length=8, max_length=1023, required=True, widget=forms.PasswordInput(attrs={
"placeholder": "Passwort",
"id": "password"
}))
stayLoggedIn = forms.BooleanField(help_text="Angemeldet bleiben?", required=False, widget=forms.CheckboxInput(attrs={
"checked": "False",
}))
class Meta:
model = User
exclude = ()
field_order = ("username", "password", "stayLoggedIn")
def clean(self):
cleaned_data = super(SignInForm, self).clean()
username = cleaned_data.get("username")
if "@" in username:
try:
username = User.objects.get(email__iexact=username).username
except ObjectDoesNotExist:
raise forms.ValidationError("Diese E-Mail-Adresse wurde nicht gefunden.")
else:
try:
username = User.objects.get(username=username).username
except ObjectDoesNotExist:
raise forms.ValidationError("Dieser Benutzername wurde nicht gefunden.")
user = authenticate(username=username, password=cleaned_data.get("password"))
print(user) #Thats always None
if not user or not user.is_active:
raise forms.ValidationError("Falsches Passwort.")
cleaned_data["user"] = user
return cleaned_data
views.py
def login(request):
if request.method == "POST":
form = SignInForm(request.POST)
if form.is_valid():
cleaned_data = form.clean()
if cleaned_data.get("user"):
auth_login(request, cleaned_data.get("user"))
try:
request.GET["next"]
except KeyError:
return redirect("homepage:homepage")
return redirect(request.GET["next"])
else:
form = SignInForm()
return render(request, "authenticate/login.html", {"form": form, "title": "Anmelden"})
