当我尝试创建帖子时,它会显示此错误

Exception Type: AttributeError at /home/
Exception Value: 'HomeView' object has no attribute 'user'

我的view.py是

class HomeView(TemplateView):
    template_name = 'home/home.html'

    def get(self, request):
        form = HomeForm()
        posts = Post.objects.all().order_by('-created')
        users = User.objects.exclude(id=request.user.id)
        friend = Friend.objects.get(current_user=request.user)
        friends = friend.users.all()

        args = {
            'form': form, 'posts': posts, 'users': users, 'friends': friends
        }
        return render(request, self.template_name, args)

    @login_required
    def post(self, request):
        if request.method == 'POST':
            form = HomeForm(request.POST or None, request.FILES or None)
            if form.is_valid():
                post = form.save(commit=False)
                post.user = request.user
                post.save()
                return redirect('home:home')
            else:
                return redirect(reverse('home:home'))
        else:
            form = HomeForm()
            args = {'form': form}
            return render(request, self.template_name, args)

请帮助

我已经失踪很久了。使用这种语言。然后帮我解决这个错误

而不是使用@login_required装饰器,在post方法上使用@method_decorator(login_required),如下所示:

from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator

class HomeView(TemplateView):
    # ...
    @method_decorator(login_required)
    def post(self, request):
        # ...

您之所以看到错误消息,是因为login_required函数装饰器 - 因此它希望request对象成为传递的第一个参数在你看来您的post定义是方法,因此selfHomeView)是第一个被传递的参数,这就是{{1尝试用作Request实例。

login_required用于将每个函数装饰器转换为方法装饰器。 See the docs for more info
