我正在玩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，他会获得表单，如果他提交表单，它将被提交给相同的view.login函数。问题是，当我尝试使用' if request.method=='POST'。我得到一个错误，'User has not attribute method'，我不明白，为什么'User'对象传递而不是request对象？这是views.py的代码：
from django.shortcuts import render
from django.http import HttpResponse, Http404, HttpResponseRedirect
from .models import Flight,Passenger
from django.urls import reverse
from django.contrib.auth import authenticate,login, logout
from django.contrib.auth.models import User
def index(request):
if not request.user.is_authenticated:
return render(request,"login.html")
context={
"flights":Flight.objects.all()
}
return render(request,"index.html",context)
def flight(request,flight_id):
flight= Flight.objects.get(pk=flight_id)
passengers = flight.passengers.all()
non_passengers = Passenger.objects.exclude(flight=flight).all()
context={
"flight":flight,
"passengers":passengers,
"non_passengers":non_passengers
}
return render(request,"flight.html",context)
def book(request,flight_id):
passenger_id = int(request.POST["passenger"])
flight = Flight.objects.get(pk=flight_id)
passenger = Passenger.objects.get(pk=passenger_id)
passenger.flight.add(flight)
return HttpResponseRedirect(reverse("flight",args=(flight_id,)))
def login(request):
print("\n In LOGIN \n")
if request.method=='POST':
print("\n In POST Request \n")
username = request.POST["name"]
password = request.POST["password"]
user = authenticate(request,username=username,password=password)
if user is not None:
login(user)
return HttpResponseRedirect(reverse("index"))
else:
return render(request,"login.html")
这是登录页面：
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<form action="{% url 'login' %}" method="POST">
{% csrf_token %}
Name<input type="text" name="name">
Password<input type="password" name="password">
<button type="submit"> Submit </button>
</form>
</body>
</html
这是错误消息（不是完整消息）：

您可以通过函数login覆盖django登录方法。只需将
def login(request):重命名为其他内容，例如
def view_login(request):，并且不要忘记更改导入和网址。
