python - 显示未找到页面(django)

Question

我的主页是登录页面。所以首先它会转到主页功能，如果没有登录，它将转到 login_user 功能，然后登录后它将重定向到主页。但显示找不到页面.这是我的代码。

views.py:

def login_user(request):
    if request.method == "POST":
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(username=username, password=password)
        if user is not None:
            if user.is_active:
                login(request, user)
                return redirect('/')
            else:
                return render(request, 'retest/login.html', {'error_message': 'Your account has been disabled'})
    else:
        return render(request, 'retest/login.html', {'error_message': 'Invalid login'})
    return render(request, 'retest/login.html')

@login_required
def home(request):
    user = request.user
    if user.groups.filter(name='hod').exists():
         return render(request, 'retest/hod.html', {})
    elif user.groups.filter(name='principal').exists():
         return render(request, 'retest/principal.html', {})
    elif user.groups.filter(name='Rep').exists():
         return render(request, 'retest/home.html', {})
    elif user.groups.filter(name='Ajithzen').exists():
         return render(request, 'event/ajithzen.html', {})
    elif user.groups.filter(name='graphics').exists():
         return render(request, 'event/ashok.html', {}) 
    elif user.groups.filter(name='Event_incharge').exists():
         return render(request, 'event/chair.html', {})
    elif user.groups.filter(name='IEEE').exists():
         return render(request, 'event/ieee.html', {})
    else:
         return redirect('/login')
