I have a custom signup form SignupForm that checks for existing email for the custom user object CustomUser and raises a ValidationError if exists. But when I try to raise the error, I get AttributeError at /accounts/signup/ Manager isn't available; 'auth.User' has been swapped for 'accounts.CustomUser'.
Here are my codes.
forms.py
from django.contrib.auth.forms import UserCreationForm
from django import forms
from django.core.exceptions import ValidationError
from django.contrib.auth import get_user_model
class SignupForm(UserCreationForm):
def __init__(self, *args, **kwargs):
super(UserCreationForm, self).__init__(*args, **kwargs)
email = forms.CharField(
widget=forms.EmailInput(
attrs={
'class': 'input',
'placeholder': 'bearclaw@example.com'
}
))
...
# other fields (username and password)
...
def clean(self):
User = get_user_model()
email = self.cleaned_data.get('email')
if User.objects.filter(email=email).exists():
raise ValidationError("An account with this email exists.")
return self.cleaned_data
views.py
from django.urls import reverse_lazy
from django.views.generic import CreateView
from .forms import SignupForm
from .models import CustomUser
...
# other views and imports
...
class CustomSignup(CreateView):
form_class = SignupForm
success_url = reverse_lazy('login')
template_name = 'registration/signup.html'
models.py
from django.db import models
from django.contrib.auth.models import AbstractUser
class CustomUser(AbstractUser):
email = models.EmailField(unique=True)
def __str__(self):
return self.username
settings.py
AUTH_USER_MODEL = "accounts.CustomUser"
What am I missing?
