Python 邮递期间Django发出警告

在提交表单和POST方法之后，我的控制台中出现了警告，我不知道该修复什么。有什么想法吗

我的

CreateView

：

class CommentCreateView(LoginRequiredMixin, CreateView):
    model = Comment
    fields = [
        'commentText'
    ]

    def form_valid(self, form):
        form.instance.commentAuthor = self.request.user
        form.instance.commentDate = datetime.now()
        form.instance.commentScenario = Scenario.objects.get(pk=self.kwargs.get('scenario_id'))
        return super().form_valid(form)

及表格：

<form method="POST" action="{% url 'comment-create' scenario.pk %}" onsubmit="setTimeout(function(){window.location.reload();},10)">
    {% csrf_token %}
    {{ newComment }}
    <div class="center">
        <button class="btn waves-effect waves-light" type="submit"value="Submit">Publish</button>
    </div>
</form>

{%csrf_令牌%}
{{newComment}}

您是否担心您粘贴的时区警告或500个错误/堆栈跟踪？这两个属性完全不相关。尤其是这个

AttributeError:“NoneType”对象没有属性“split”

和

AttributeError:“Comment”对象没有属性“get\u absolute\u url”

当试图处理引发的原始异常时，这些情况会进一步发生。您需要查看原始异常并从那里开始。这就是问题所在：

AttributeError:“Comment”对象没有属性“get\u absolute\u url”

。您需要在

注释

模型上定义该函数。看看这里：也看看这个答案。这可能会有帮助：好的，我将

def get_absolute\u url（self）：return reverse（'scenario-detail'，kwargs={'pk'：self.pk}）

添加到我的

models.py

中，这个警告不再存在。但是现在这个

AttributeError:'NoneType'对象没有属性“split”

和所有500个属性会怎么样？有什么建议吗？
