Question

当前在注册过程中，当用户输入现有用户名和电子邮件时，系统会通知该用户名已存在于数据库中。当用户输入其他用户名但存在一封电子邮件时，将在db中成功创建用户。所以我想验证数据库中是否存在电子邮件。因此，我创建了以下内容，但不幸的是，它无法按预期工作（如果存在相同的电子邮件，则会创建用户）。

forms.py文件

from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
from django import forms


class SignupForm(UserCreationForm):
    email = forms.EmailField(required=True)

    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']

def clean_email(self):
    # Get the email
    email = self.cleaned_data.get('email')
    if User.objects.filter(email__iexact=email).exists():
        raise forms.ValidationError("User with that email already exists")
    return email

views.py文件

from django.shortcuts import render
from django.contrib.messages.views import SuccessMessageMixin
from django.views import generic
from django.contrib.auth.forms import UserCreationForm
from django.urls import reverse_lazy


from .forms import SignupForm


class UserRegisterView(SuccessMessageMixin, generic.CreateView):
    form_class = SignupForm
    template_name = 'registration/register.html'
    success_url = reverse_lazy('login')
    success_message = "Hello %(username)s! Your account has been created"

谢谢您的时间。
