Python 在Django中{%if user.is_autenticated%}不工作

我在Django中创建了一个登录系统，但它无法在html文件中使用{%if user.is_autenticated%}方法。它总是以“未登录”的方式工作，而且当我登录时，我不理解问题所在。有人能帮我吗？谢谢你的帮助和支持 这是我的代码：

视图.py

# Form Post 
class EditView(ListView):
    model = Article
    form_class = ArticleForm
    template_name = 'blog/form_post/index.html'
    ordering = ['-data']

class AddPostView (CreateView): # Create new Post
    model = Article
    form_class = ArticleForm
    template_name = 'blog/form_post/add_post.html'

class EditPostView(UpdateView): # Edit a post
    model = Article
    form_class = ArticleForm
    template_name = 'blog/form_post/edit_post.html'

class DeletePostView(DeleteView):
    model = Article
    template_name = 'blog/form_post/delete.html'
    success_url = reverse_lazy('EditHome')
# Login 
def Slogin(request):
    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')
        user = authenticate(request, username = username, password = password)
        if user is not None:
            login(request, user)
            return redirect('EditHome')
        else:
            messages.info(request, 'Error')
    context = {}
    return render(request,'blog/form_post/Slogin.html' )
...

您有一个输入错误。它应该是

用户。是否经过身份验证
