Reverse_Lazy 没有将我重定向到 sprcified URL

问题描述

我想为我的用户和超级用户制作一个按钮，以便能够在 Django 管理中删除他们的帖子。当我点击删除按钮时，它既不会将我重定向到指定的 URL，也不会删除帖子。我使用 mixins 是为了让管理员删除每个人的每个帖子，但用户只能删除他们的帖子。

#MIXIN.py

class DeleteArticleAccessMixin():
def dispatch(self,request,pk,*args,**kwargs):
    article = get_object_or_404(Article,pk=pk)
    if article.author == request.user or request.user.is_superuser:
        return super().dispatch(request,**kwargs)
    else:
        raise Http404("Access Denied!")

#Views.py

class ArticleDelete(DeleteArticleAccessMixin,DetailView):
model = Article
success_url = reverse_lazy('account:home')
template_name = "registration/article_confirm_delete.html"

#urls.py

path('article/delete/<int:pk>',ArticleDelete.as_view(),name="article-delete"),

#我的主页 HTML 页面

 {% if user.is_superuser or user.is_author %}
  <a class="badge text-danger badge-primary"
  href="{% url "account:article-delete"  article.pk %}">Delete Article</a>
  {% endif %}

#My Html 删除页面

        <div class="col-md-8 text-center mx-auto">
            <div class="card card-danger">
              <div class="card-header">
                <h3 class="card-title">Delete Article</h3>
              </div>
                <div class="card-body py-4">
             <form method="post">{% csrf_token %}
    <p class="py-2">Are you sure you want to delete "{{ object }}" written by
    "{{ object.author.get_full_name }}"?</p>
    <input type="submit" value="Confirm" class="btn btn-danger">
</form>
                </div>
            </div>
    </div>

解决方法

这是有道理的，因为您的 DeleteArticleAccessMixin 永远不会删除某些内容。它只检查您的用户是否具有适当的访问权限。您可以从 DeletionMixin [Django-doc] 子类化。您还可以通过覆盖 get_queryset:

来进一步控制访问

from django.views.generic.edit import DeletionMixin

class ArticleDelete(DeletionMixin,DetailView):
    model = Article
    success_url = reverse_lazy('account:home')
    template_name = 'registration/article_confirm_delete.html'

    def get_queryset(self,*args,**kwargs):
        qs = super().get_queryset(*args,**kwargs)
        if self.request.user.is_superuser:
            return qs
        return qs.filter(
            author=self.request.user
        )
