Question

如果我在提交后从页面登录创建新用户，如果一切正常，我会使用 login(request,user) 自动登录并在主页中重新重定向用户。在这种情况下，脚本有效。但是，如果我注销并随后登录，authenticate() 返回 None 并且身份验证失败。

models.py

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


class User(AbstractUser):
    pass


class Email(models.Model):
    user = models.ForeignKey("User", on_delete=models.CASCADE, related_name="emails")
    sender = models.ForeignKey("User", on_delete=models.PROTECT, related_name="emails_sent")
    recipients = models.ManyToManyField("User", related_name="emails_received")
    subject = models.CharField(max_length=255)
    body = models.TextField(blank=True)
    timestamp = models.DateTimeField(auto_now_add=True)
    read = models.BooleanField(default=False)
    archived = models.BooleanField(default=False)

    def serialize(self):
        return {
            "id": self.id,
            "sender": self.sender.email,
            "recipients": [user.email for user in self.recipients.all()],
            "subject": self.subject,
            "body": self.body,
            "timestamp": self.timestamp.strftime("%b %d %Y, %I:%M %p"),
            "read": self.read,
            "archived": self.archived
        }

注册视图

def register(request):
    if request.method == "POST":
        email = request.POST["email"]

        # Ensure password matches confirmation
        password = request.POST["password"]
        confirmation = request.POST["confirmation"]
        if password != confirmation:
            return render(request, "mail/register.html", {
                "message": "Passwords must match."
            })

        # Attempt to create new user
        try:
            user = User.objects.create_user(email, email, password)
            user.save()
        except IntegrityError as e:
            print(e)
            return render(request, "mail/register.html", {
                "message": "Email address already taken."
            })
        login(request, user)
        return HttpResponseRedirect(reverse("index"))
    else:
        return render(request, "mail/register.html")

登录视图

import json
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.decorators import login_required
from django.db import IntegrityError
from django.http import JsonResponse
from django.shortcuts import HttpResponse, HttpResponseRedirect, render
from django.urls import reverse
from django.views.decorators.csrf import csrf_exempt

from .models import User, Email

def login_view(request):
    if request.method == "POST":

        # Attempt to sign user in
        email = request.POST["email"]
        password = request.POST["password"]
        user = authenticate(request, user=email, password=password)

        # Check if authentication successful
        if user is not None:
            login(request, user)
            return HttpResponseRedirect(reverse("index"))
        else:
            return render(request, "mail/login.html", {
                "message": "Invalid email and/or password"})
    else:
        return render(request, "mail/login.html")

首次注销后Django身份验证（）不起作用
