Django Blog并非所有数据都被导入

我目前正在从事我的第一个Django项目“不遵循教程”。我正在创建一个博客,并尝试获取所有图片和帖子数据以导入帖子。我正在导入一些信息,但不是全部。具体来说,我的图片和日期没有被填充到帖子中。

views.py --------------------------------

     def home(request):
        context= {
            'posts' : Post.objects.all(),
            'comment': Comment.objects.all(),
        }
        return render(request, 'blog/home.html', context)


    def base(request):
        return render(request, 'blog/test.html')

class ArticleDetailView(DetailView):
    model = Post
    template_name = 'blog/standard.html'

------我的HTML页面
