Question

我有以下代码，我收到一条错误消息：“User对象没有属性POST”

def login (request):
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
            login(user)
            return render(request, 'base_in/base_in.html', {})
        else:
            return render(request, 'signupapp/error.html', {'message':'the acount is not active'})
    else:
        return render(request, 'signupapp/error.html', {'message':'username and password is incorrect'})

我也尝试了这段代码并得到了另一个错误：“login（）需要1个位置参数但是2个被赋予”

def login (request):
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
            login(user)
            return render(request, 'base_in/base_in.html', {})
        else:
            return render(request, 'signupapp/error.html', {'message':'the acount is not active'})
    else:
        return render(request, 'signupapp/error.html', {'message':'username and password is incorrect'})

我做错了什么？基于django教程，它应该正常工作：

Answer 1

您尝试拨打login的{{1}}时发生了什么事，但您也定义了自己的from django.contrib.auth函数，这里有一种名称冲突。

您应该将其重命名为其他内容，例如login()

login_view()

如果您不想重命名，可以使用其他名称导入Django from django.contrib.auth import authenticate, login def login_view(request): # If you call it login, # you get conflict with login imported aove # The rest of your code here # now if you call login(user), it will use the correct one, # i.e. the one imported from django.contrib.auth，例如

login

Answer 2

我建议先添加登录表单

class LoginForm(forms.Form):
   username = forms.CharField()
   password = forms.CharField(widget=forms.PasswordInput)#hides password on input

然后

from django.http import HttpResponseRedirect,HttpResponse
from django.contrib.auth import authenticate, login
.
.


def user_log(request):
  #if you add request.method=='POST' is it a bug i dont know y
  if request.method:
    form = LoginForm(request.POST)
    if form.is_valid():
        cleandata=form.cleaned_data
        #authenticate checks if credentials exists in db
        user=authenticate(username=cleandata['username'],
                          password=cleandata['password'])
        if user is not None:
            if user.is_active:
                login(request, user)
                return HttpResponseRedirect("your template")
            else:
                return HttpResponseRedirect("your templlate")
        else:
            return HttpResponse("Invalid login")
    else:
        form=LoginForm()
    return render(request, 'registration/login.html',{'form':form})

login is working but i want to login using model value like username and password
def login(request):
    if request.method=='POST':
        username1=request.POST['username']
        password1=request.POST['password']
        user=authenticate(username=username1,password=password1)
        if user is not None:
            if user.is_active:
                dj_login(request, user)
                return render(request,"products/dashboard.html")
            else:
                print("user is not active")
        else:
            messages.error(request,'Username and Password is invalid')
            return render(request,'products/login.html')
    else:
        return render(request,'products/login.html')
