我试过这个if form.is_valid() and request.user.is_authenticated():
,它告诉我,bool obj 是不可调用的。 然后我尝试没有括号,然后它显示错误,"注释表单"对象没有属性cleaned_data
。 请帮助我,将不胜感激。
def post_detail(request, slug=None):
instance = get_object_or_404(Post, slug=slug)
if instance.publish > timezone.now().date() or instance.draft:
if not request.user.is_staff or not request.user.is_superuser:
raise Http404
share_string = quote_plus(instance.content)
initial_data = {
"content_type": instance.get_content_type,
"object_id": instance.id
}
form = CommentForm(request.POST or None, initial=initial_data)
if form.is_valid() and request.user.is_authenticated():
c_type = form.cleaned_data.get("content_type")
content_type = ContentType.objects.get(model=c_type)
obj_id = form.cleaned_data.get('object_id')
content_data = form.cleaned_data.get("content")
parent_obj = None
try:
parent_id = int(request.POST.get("parent_id"))

if parent_id:

return HttpResponseRedirect(new_comment.content_object.get_absolute_url())
comments = instance.comments
context = {
"title": instance.title,
"instance": instance,
"share_string": share_string,
"comments": comments,
"comment_form":form,

return render(request, "post_detail.html", context)
只是is_authenticated
不需要括号。
if form.is_valid() and request.user.is_authenticated:
