我正在开发一个 Django 应用程序，但似乎无法运行我的第一个测试，因为与固定装置相关的错误。当我执行“python manage.py test”时，出现此错误:
堆栈跟踪

},
{
"model": "poll",

"event": 1,
"title": "Food"
}
}
]
请您参考如下方法:
你应该检查你的灯具，模型值必须是以下格式:
app_name.model_name
例如(考虑包含事件模型的应用程序被命名为事件):
[
{
"model": "events.event",
"fields": {
"pk": 1,
"title": "Monty Python at the Hollywood Bowl"
}
},
]
希望对你有帮助
