python - Django身份验证错误: 'str' object has no attribute 'pk'

Question

我在 Django 身份验证中遇到问题，每当我尝试登录时，都会出现“str”对象没有属性“pk”错误。我使用 MySql 作为我的数据库。

# views.py
def user_login(request):
 if request.method == 'POST':
     form = AuthenticationForm(request,data=request.POST)
     if form.is_valid():
         username = form.cleaned_data.get('username')
         password = form.cleaned_data.get('password')
         user = authenticate( username= username,password= password)
         if user is not None:
             login(request,username)
             return redirect('app:home')
         else:
             return render(request,'404error.html',context={})
     else:
         return render(request,'404error.html',context={})

 form = AuthenticationForm()
 return render(request,'login.html',context={'form':form})

def user_logout(request):
 logout(request)
 return redirect('app:home')

#urls.py
# from django.contrib import admin
from django.urls import path,include
# from app import urls
from . import views
app_name = 'app'

urlpatterns = [

    path('',views.home,name='home'),
    path('register/',views.register,name='register'),
    path('login/',views.user_login,name='user_login'),

]

你应该login(..) [Django-doc] User 对象，因此 user，而不是 username，因此:

    …
    login(request, <b>user</b>)
    …
