如何删除答案（正文中的代码）？

Question

我正在创建一个Q&；一个用于实践的网站，我创建了答案和问题模型并将它们链接在一起，但是我无法访问为删除答案模型而设置的模板，我创建了一个DeleteView来删除问题。代码如下：

视图.py：

class Politics_post_details(DeleteView):
    model = PoliticsPost
    context_object_name = 'politicsposts'
    pk_url_kwarg = 'qid'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        # now you can get any additional information you want from other models
        question = get_object_or_404(PoliticsPost, pk=self.kwargs.get('qid'))
        context['answers'] = Answer.objects.filter(post=question).order_by('-date_posted')
        return context

class AnswerDelete(UserPassesTestMixin,DetailView):
    model = Answer
    success_url = reverse_lazy('Lisk home')
    pk_url_kwarg = 'aid'

    def test_func(self):
        answer = self.get_object()
        if self.request.user ==answer.author:
            return True
        return False

url.py（非根目录）：

path('politicspost/<int:qid>/createanswer/',views.CreateAnswer.as_view(template_name='lisk_templates/createanswer.html'),name = 'Answer'),
path('politicspost/<int:qid>/answer/<int:aid>/delete/',views.AnswerDelete.as_view(template_name = 'lisk_templates/answer_delete.html'),name='Answer_Delete'), 
path('politicspost/<int:qid>/',views.Politics_post_details.as_view(template_name='lisk_templates/politics_post_details.html'),

我创建了模板，但每当我尝试访问它时，它都会给我一个错误，如下所示：

NoReverseMatch at /politicspost/29/
Reverse for 'Answer_Delete' with arguments '(36,)' not found. 1 pattern(s) tried: ['politicspost/(?P<qid>[0-9]+)/answer/(?P<aid>[0-9]+)/delete/$']

提前谢谢

答案_delete.html：

{%extends "lisk_templates/base.html"%}
{% block title %}
    Page title
{% endblock title %}

{% block body%}

<div class="feed" style="background-color:lightred;"><form method="POST">
    {% csrf_token %}
    <h3>Are you sure that you want to delete this answer: <br>
        {{ object.content }}</h3>
    <button id="signin" type="submit">Yes</button>  <a href="{% url 'politics_post_details' object.id %}" style="margin-left:10px;"> No</a>
    </form>
</div>
{% endblock body %}

Answer 1

这可能对您有用，因为您从未使用过DeleteView的导入

from django.views.generic import DeleteView

"""This Is From My Blog App, That I Used For My Blog App, Hope This Will Help"""
class PostDeleteView(LoginRequiredMixin, DeleteView):
    model = Post
    success_url = reverse_lazy('post_list')

快乐编码，如果这个有任何问题，请告诉我，我支持你

你有很多问题。最大的一个是，您已经切换了DeleteView和DetailView（您的DeleteView是DetailView，反之亦然）

然后您应该将模板重命名为answer_confirm_delete，或者将template_name_suffix添加到DeleteView。有关更多详细信息，请参阅文档：

https://docs.djangoproject.com/en/3.0/ref/class-based-views/generic-editing/#django.views.generic.edit.DeleteView

如果使用Django的DeleteView，则不需要在模板中指定url，它将为您完成所有工作。只需确保在urls.py中正确指定url即可。解决这些问题，然后看看它是否有效
