如何在ListViewDjango中使用表单？

Question

我正在尝试为ListView创建一个操作，该操作将删除或更改模型中表中的参数，例如，禁用用户，使用复选框。 如果我选择了所有这些选项并单击此按钮，则会删除所有选定项。在

在**视图.py在

class AccountsManagementView(LoginRequiredMixin, generic.ListView):
    """
    Class Based View para a manipulação de usuários.
    """
    model = User
    template_name = 'accounts/accounts_management.html'
    context_object_name = 'users'


    def get_queryset(self):
        return User.objects.all()

class DeleteUser(DeleteView):
    model = User
    success_url = reverse_lazy('accounts:accounts_manager')

在**网址.py在

模板/帐户_管理.html在

Answer 1

你可以做的是让表单返回你想要删除的对象的pk列表。在

然后你做一些类似的事情：

def delete_view(request):
    if request.method == "post":
        data = [] # Array of pks
        User.objects.filter(pk__in=data).delete()

这应该能满足你的要求。在

如果这对你没有帮助的话，也许谷歌会批量删除django。似乎是以前存在的功能，但现在不再受支持。在

看看generic.UpdateView查看例如使用post（）方法的CBV示例。在这里，您可以引入一个表单，验证输入，并处理—在您的情况下，查看每个复选框的值并相应地处理记录。在

您可能不需要像泛型视图那样将逻辑分解为多个方法，除非您希望使其可重用。在
