python - 在模板上使用 for 循环时不会显示来自 Listview 的对象 - Django

Question

我正在尝试通过在模板（landingpage.html）上使用for循环在Listview中显示Company中的所有对象，但它显示为空。对我来说棘手的部分是模型类（公司）来自与创建列表视图的目录不同的目录。我在 views.py 中导入模型类（公司），但它在模板上仍然显示为空。

关于为什么会这样的任何想法？

from company.models import Company

class LandingpageView(ListView):
    model = Event
    template_name = "event/landingpage.html"
    ordering = ['date']
    context_object_name = 'event_list'

class LatestCompanyView(ListView):
    model = Company
    template_name = "event/landingpage.html"
