数据库中不存在匹配查询

如何解决数据库中不存在匹配查询

每当我尝试获取查询中的项目列表时，我都会收到此错误

从 django.db 导入模型

在此处创建您的模型。

class Todo(models.Model):
    name  = models.CharField(max_length = 200)
    
    def __str__(self):
        return self.name
    
    
class Item(models.Model):
    todolist = models.ForeignKey(Todo,on_delete = models.CASCADE)
    text = models.CharField(max_length = 300)
    complete = models.BooleanField()
        
    
    def __str__(self,text = text):
        return self.text 

我在 pycharm 终端中执行的那行

In [3]: lt = Todo.objects.get(id = 1)
---------------------------------------------------------------------------

     86             manager_method.__name__ = method.__name__
     87             manager_method.__doc__ = method.__doc__

    433             return clone._result_cache[0]
    434         if not num:
--> 435             raise self.model.DoesNotExist(
    436                 "%s matching query does not exist." %
    437                 self.model._Meta.object_name

DoesNotExist: Todo matching query does not exist.
