我一直想弄明白为什么我总是得到 *“object of type 'method' has no len（）"，它将我引导到这一行。请帮助我一直在它在过去的3天，我真的想拉我的头发了。

from django.core.paginator import Paginator

def index(request):
    allPosts = Post.objects.all().order_by("id").reverse

    #paginator
    paginator = Paginator(allPosts, 10)
    page_number = request.GET.get('page')
    *posts_of_page = paginator.get_page(page_number)*

    return render(request, "network/index.html", {
        "allPosts" : allPosts,
        "posts_of_page" :  posts_of_page,
    })
