Question

我想列出来自两个不同模型“ Post”和“ Superpost”的帖子但是我该如何访问呢？

def post_list(request):
    list_posts = Post.objects.get_queryset().order_by('-pk')
    paginator = Paginator(list_posts, 10)  # Show 10 Posts per page
    page = request.GET.get('postpage')
    posts = paginator.get_page(page)
    categories = Category.objects.all()

    return render(request, 'MyProject/post_list.html', {'posts': posts, 'categories':categories})

感谢您的所有答复，我解决了这样的问题：

def post_list(request):
    list_posts = list(chain(Post.objects.get_queryset().order_by('-pk'), Post_Sell_Multiple.objects.get_queryset().order_by('-pk')))
    paginator = Paginator(list_posts, 10)  # Show 10 Posts per page
    page = request.GET.get('postpage')
    posts = paginator.get_page(page)
    categories = Category.objects.all()

    return render(request, 'MyProject/post_list.html', {'posts': posts, 'categories':categories})

您应该首先查询SuperPost模型，然后像这样链接Post和SuperPost查询集：

from itertools import chain

def post_list(request):
    list_posts = Post.objects.get_queryset().order_by('-pk')
    list_super_posts = SuperPost.objects.get_queryset().order_by('-pk')
    result_list = list(chain(list_posts, list_super_posts))
    paginator = Paginator(result_list, 10)  # Show 10 Posts per page
    page = request.GET.get('postpage')
    posts = paginator.get_page(page)
    categories = Category.objects.all()

    return render(request, 'MyProject/post_list.html', {'posts': posts, 
                  'categories':categories})

Django在同一页面上显示两个不同的模型对象
