Python 将模型实例对象添加到模板

我得到这个错误，我不知道如何修复它。我最终想为我的相册添加一个缩略图，点击后我将能够看到相册中的所有照片

我试图在数据库中添加所有相册模型对象，并列出同一相册中的所有照片。我试图首先列出我的模板上的相册，看看我得到了什么值，但我得到了这个错误

home.html中包含的portfolio.html

  <div class="col-md-4 col-sm-6 portfolio-item">
    <a href="#" class="portfolio-link">
      <div class="portfolio-hover">
        {{ albums }}
      </div>
      <img src="{{ STATIC_URL }}home/images/roundicons.png">
    </a>

渲染函数的第三个参数必须是字典

return render(request, 'home/home.html', {'albums': albums})

由于某种原因，在您的视图中多次出现相同的错误代码
