Django- 我如何获取与另一个模型相关的模型的内容？

Question

所以我正在创建一个待办事项应用程序。如何查看链接到版块的任务？就像我理解的那样，董事会需要成为任务的外键。这是我到目前为止的代码：Models.pyclass Board(models.Model):id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)admin = models.ForeignKey(User, on_delete=models.CASCADE, related_name="Board")name = models.CharField(max_length=200)class Task(models.Model):    board = models.ForeignKey(Board, on_delete=models.CASCADE)    admin = models.ForeignKey(User, on_delete=models.CASCADE)    text = models.CharField(max_length=300)    complete = models.BooleanField(default=False)    assigned_to = models.CharField(max_length=30)views.pydef board_post_detail(request, board_id):obj = get_object_or_404(Board, id=board_id)context = {"object": obj}return render(request, 'boards/board_post_detail.html', context)board_post_detail.html{% block content %}<h1>{{ object.name}}</h1><p>Created by {{object.admin.username  }}</p>{% endblock %}

Answer 1

如果要查找与 Board 类的特定实例对应的任务，则只需按实例进行查询筛选：

obj = get_object_or_404(Board, id=board_id)
Task.objects.filter(board=obj)
