我希望能够在同一个页面或Django模板上渲染、显示或访问列表视图和细节视图。下面是我目前为止的尝试。这里是一个链接，我在那里得到了一个非常相似但有限的代码来解决这个问题。（DJANGO: How to access data from ListView and DetailView on the same template?）
结果当我runserver.py显示一个完全空白的页面，没有一个错误，甚至在终端上请帮助我解决这个问题。
models.py

class Reports(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True)

    name = models.CharField(max_length=255) 
    email = models.EmailField(max_length = 254)
    phone =  models.CharField(max_length=11) 
    address = models.CharField(max_length=255, blank=True, null=True)
    subject = models.CharField(max_length=255)
    message = models.TextField(blank=True, null=True)
    
    created = models.DateTimeField(auto_now_add=True)
    due = models.DateTimeField(auto_now_add=False, auto_now=False, blank=True, null=True)
