在 Django 中使用装饰器在基于类的视图中转换函数

Question

我有这个代码：

#decorators.py
from django.contrib.auth.decorators import user_passes_test


def superuser_required(func):
    return user_passes_test(
        lambda u: u.is_authenticated() and u.is_superuser)(func)



# views.py
@superuser_required
def dashboard_candidates(request):
    persons = Person.objects.all()
    return render(request, 'my_template.html', {'persons': persons})

如何在ListView中改造这个函数来适配装饰器？

我试试：

PersonList(LoginRequiredMixin, ListView)
    model = Person
    paginate_by = 10

我不知道如何实现上面提到的装饰器。

Engraçado, só funcionou desse jeito。

from django.utils.decorators import method_decorator


class SuperuserRequiredMixin(object):

    @method_decorator(user_passes_test(lambda u: u.is_authenticated() and u.is_superuser))
    def dispatch(self, *args, **kwargs):
        return super(SuperuserRequiredMixin, self).dispatch(*args, **kwargs)


class PersonList(SuperuserRequiredMixin, ListView):
    model = Person
    paginate_by = 20
