'Post' 对象不可迭代，即使我正在使用过滤器

Question

我正在尝试获取特定车辆的所有帖子，这是我拥有的代码：


*vehicles/views.py*
class UserVehicleListView(ListView):
    model = Vehicle
    template_name = 'vehicles/vehicles.html'  # <app>/<model>_<viewtype>.html
    context_object_name = 'vehicles'
    
    def get_queryset(self):
        print(Vehicle.objects.filter(owner_id= self.request.user.id))
        return Vehicle.objects.filter(owner_id= self.request.user.id)

class UserVehicleDetailView(DetailView):
    model = Post
    template_name = 'vehicles/vehicle_detail.html'  # <app>/<model>_<viewtype>.html
    context_object_name = 'posts'


    def get_queryset(self):

        vehicle = get_object_or_404(Vehicle, id =self.kwargs.get('pk'))
        
        print(Post.objects.filter(vehicle= vehicle))
        return Post.objects.filter(vehicle= vehicle)


*vehicles/urls.py*


urlpatterns = [
    path('vehicles/', UserVehicleListView.as_view(), name='vehicle-list'),
    path('vehicles/<int:pk>/',  UserVehicleDetailView.as_view() , name='vehicle-detail'),

]

urlpatterns += staticfiles_urlpatterns()

*vehicles/templates/vehicles/vehicle.html*

  {% for vehicle in vehicles %}

    
      <div class="col-lg-6 mb-3 mb-lg-0">
       
          <div class="hover-overlay" ></div>
          <div class="hover-1-content px-5 py-4">
            <a href=" {%url 'vehicle-detail' vehicle.id %}">
             
            <h3 class="hover-1-title text-uppercase font-weight-bold mb-0"> <span class="font-weight-light">Volvo </span></h3>
          </a>

            <p class="hover-1-description font-weight-light mb-0">Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
          </div>
      {%endfor%}

*vehicles/templates/vehicles/vehicle_detail.html*

{% extends "blog/base.html" %}
{% block content %}
<article class="media content-section">
<h2>
    {% for post in posts %}

    {{post.date_posted}}
    {%endfor%}
</h2>



</article>
{% endblock content %}

当我使用 Vehicle.objects.filter(owner_id= self.request.user.id) 打印时，我进入命令：

, ]> 但是当我在 vehicle_detail.html 中使用 for 循环传递值时，我得到：

** /vehicles/1/'Post' 对象的类型错误不可迭代**

当我通过 {{object.date_posted}} 我只得到 1 Post，我如何通过所有帖子？在此先感谢您的帮助！

发现了问题，我传递的是 DetailView 而不是 ListView

'Post' 对象不可迭代，即使我正在使用过滤器

'Post' object is not iterable even though i'm using filter
