Django DetailView + 显示另一个Model的相关记录

Question

我想返回用户相关记录。有人可以帮助我吗？

我的部分观点

class UserProfileDetailView(DetailView):
    model = get_user_model()
    slug_field = "username" 
    template_name = "perfil.html"

    def get_object(self, queryset=None):
        user = super(UserProfileDetailView, self).get_object(queryset)
        UserProfile.objects.get_or_create(user=user)
        return user


Something like a old way>
def my_view(request, slug):
    var = get_object_or_404(Model, slug=slug)
    xxx = AnotherModel.objects.filter(var=var)
...

我如何在第一个 View UserProfileDetailView 中执行此操作，显示相关数据？

Answer 1

在这种情况下，我所做的是将相关对象添加到上下文数据中。它会是这样的:

class UserProfileDetailView(DetailView):
    model = get_user_model()
    slug_field = "username" 
    template_name = "perfil.html"

    def get_context_data(self, **kwargs):
        # xxx will be available in the template as the related objects
        context = super(UserProfileDetailView, self).get_context_data(**kwargs)
        context['xxx'] = AnotherModel.objects.filter(var=self.get_object())
        return context
