Python Django教程第5部分错误

我在学习Django编程

我在玩第五部分

我会把地址留在下面

我添加了测试文件的内容

但是我做了测试，但是测试文件有问题

我试着找一个打字错误，但找不到

有什么问题

这是回溯

回溯最近一次呼叫上次： 文件/home/choco/python3/django/mysite/polls/tests.py，第96行，在两个过去的问题中 创建问题文本=过去的问题1，天数=-30 NameError:未定义名称“创建问题” ----------------------------------- 在0.103秒内运行了8次测试 失败错误=5

正在销毁别名“default”的测试数据库…您已缩进create_question，以便它位于QuestionModelTests类中。我认为您不是有意这么做的-它不在该类中使用，也不引用任何类属性。您应该取消对它的登录，以便它位于所有类之外。

您需要了解有关OOP的更多信息。检查此代码并更正：
