在Django 3中使用类基视图实现不区分大小写的用户名和电子邮件

AUTH_USER_MODEL = 'myapp.CustomUser'

from django.contrib.auth.models import AbstractUser
from django.db import models

class CustomUser(AbstractUser):
    email = models.EmailField(unique=True)

    def normalize_username(self, username):
        return username.lower()

from django.urls import path
from myapp.views import UserCreateView, UserUpdateView

urlpatterns = [
    path('register/', UserCreateView.as_view(), name='register'),
    path('profile/update/', UserUpdateView.as_view(), name='profile_update'),
]

from django.contrib.auth.mixins import LoginRequiredMixin
from django.urls import reverse_lazy
from django.views.generic import CreateView, UpdateView
from myapp.models import CustomUser
from myapp.forms import UserForm

class UserCreateView(CreateView):
    model = CustomUser
    form_class = UserForm
    template_name = 'register.html'
    success_url = reverse_lazy('login')

class UserUpdateView(LoginRequiredMixin, UpdateView):
    model = CustomUser
    form_class = UserForm
    template_name = 'profile_update.html'
    success_url = reverse_lazy('profile_update')
