我只是在玩 Django 登录和注销阶段。我有一个登录页面，如果用户使用“GET”获取它，他就会获取表单，如果他提交表单，它就会提交给相同的view.login函数。问题是当我尝试使用\' if request.method==\'POST\'. 我收到一个错误\'User has not attribute method\'，我不明白，为什么\'User\'传递的是对象而不是request对象？\n这里是views.py的代码：
from django.shortcuts import render\nfrom django.http import HttpResponse, Http404, HttpResponseRedirect\nfrom .models import Flight,Passenger\nfrom django.urls import reverse\nfrom django.contrib.auth import authenticate,login, logout\nfrom django.contrib.auth.models import User\n\n\ndef index(request):\n if not request.user.is_authenticated:\n return render(request,"login.html")\n\n context={\n "flights":Flight.objects.all()\n }\n return render(request,"index.html",context)\n\ndef flight(request,flight_id):\n flight= Flight.objects.get(pk=flight_id)\n passengers = flight.passengers.all()\n non_passengers = Passenger.objects.exclude(flight=flight).all()\n context={\n "flight":flight,\n "passengers":passengers,\n "non_passengers":non_passengers\n }\n return render(request,"flight.html",context)\n\ndef book(request,flight_id):\n passenger_id = int(request.POST["passenger"])\n flight = Flight.objects.get(pk=flight_id)\n passenger = Passenger.objects.get(pk=passenger_id)\n passenger.flight.add(flight)\n return HttpResponseRedirect(reverse("flight",args=(flight_id,)))\n\ndef login(request):\n print("\\n In LOGIN \\n")\n if request.method==\'POST\':\n print("\\n In POST Request \\n")\n username = request.POST["name"]\n password = request.POST["password"]\n user = authenticate(request,username=username,password=password)\n if user is not None:\n login(user)\n return HttpResponseRedirect(reverse("index"))\n else:\n return render(request,"login.html")\n这是登录页面：
\n\n<html>\n<head>\n<meta charset="utf-8">\n\n</head>\n<body>\n <form action="{% url \'login\' %}" method="POST">\n {% csrf_token %}\n Name<input type="text" name="name">\n Password<input type="password" name="password">\n <button type="submit"> Submit </button>\n </form>\n</body>\n\n\n</html\n这是错误消息（不是完整消息）：

您可以通过您的函数覆盖 django 登录方法login。只需重命名
def login(request):
例如其他东西
def view_login(request):
并且不要忘记更改导入和网址。
