'User' 对象没有属性 'method'

Question

我只是在玩弄 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，他会得到表单，如果他提交表单，它会被提交到相同的 view.login 函数。问题是当我尝试使用 ' if request.method=='POST' 时。我得到一个错误 'User has not attribute method'，我不明白，为什么 'User' 对象而不是 request 对象被传递？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）：

Answer 1

您通过函数 login 覆盖了 django 登录方法。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 url。

'User' 对象没有属性 'method'

'User' Object has no attribute 'method'

python

django
