我正在尝试使用 django.contrib.auth authenticate() 方法中的默认 Django 来验证用户是否存在。我在用户注册后立即执行此操作。用户注册并且他们的username、email和password被输入到database然后他们被带到login page但是它不起作用。
这是我的 views.py
from django.shortcuts import render,redirect
from .models import Student
from django.contrib.auth.models import User
from django.contrib.auth import authenticate, login
# Create your views here.
def index(request):
if request.method == "POST":
fname = request.POST.get('fname')
lname = request.POST.get('lname')
pnumber = request.POST.get('pnumber')
email = request.POST.get('email')
password = request.POST.get('password')
student = Student(fname = fname, lname = lname, pnumber = pnumber, email = email,
password = password)
student.save()
user = User.objects.create_user(fname, email, password)
user.save()
return render(request, ('SignUpPage.html'))
def loginUser(request):
if request.method == "POST":
email = request.POST.get('email')
password = request.POST.get('password')
user = authenticate(email=email, password=password)
if user is not None:
login(request, user)
return redirect('mainPage')
else:
return render(request, ('LoginPage.html'))
return render(request, ('LoginPage.html'))
def mainPage(request):
return render(request, ('MainPage.html'))这是我的 urls.py
from django.contrib import admin
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
path('login', views.loginUser, name="login"),
path('mainPage',views.mainPage, name='mainPage')
]这是我的 html 代码

您正在尝试使用电子邮件进行身份验证，基本 Django 的身份验证是使用用户名。如果你想使用电子邮件，你必须告诉 Django。将此添加到您的 User 模型中：
class User(...):
...
USERNAME_FIELD = "email"
...您还说用户注册了 username，但您只使用了 fname 和 lname。请具体并阅读您所写的内容，否则我们无法为您提供帮助。
