Question

我想在删除后删除数据库content.bt utl转到http://127.0.0.1:8004/login/delete_detail/6/ ..我可以重定向到success.html，即在同一页面

class DeleteView(generic.TemplateView):
    template_name = 'success.html'
    success_url='/login/success'
    def get_context_data(self, *args, **kwargs):
        context = super(DeleteView,self).get_context_data(**kwargs)
        did = self.kwargs['did']
        q_obj = Quest.objects.filter(id=did)
        q_obj.delete()

Answer 1

您可以使用get_success_url方法：

from django.urls import reverse_lazy

class DeleteView(generic.TemplateView):
    template_name = 'success.html'
    success_url='/login/success'
    def get_context_data(self, *args, **kwargs):
        context = super(DeleteView,self).get_context_data(**kwargs)
        did = self.kwargs['did']
        q_obj = Quest.objects.filter(id=did)
        q_obj.delete()

    def get_success_url(self, **kwargs):         
        return reverse_lazy('delete_detail', kwargs = {'pk': self.kwargs['did']})

您也可以使用DeleteView class：

代替TemplateView

class QuestDelete(DeleteView):
    model = Quest
    pk_url_kwarg = 'did'

    def get_success_url(self, **kwargs):         
        return reverse_lazy('delete_detail', kwargs = {'pk': self.kwargs['did']})

要使用url的名称，您需要在urls.py文件中的url模式中添加name参数，如下所示：

urlpatterns = [
    path('delete_detail', views.delete_detail, name='delete_detail'),
]

Answer 2

您应该覆盖get_success_url方法。例如：

def get_success_url(self):

     return reverse_lazy('delete-success')

另外，请尝试在success_url

中使用已命名的网址

success_url = reverse_lazy('delete-success')

当数据库内容删除时，如何使用url参数传递方法重定向到同一页面？
