Django测试开发-25- 所有app应用整理至apps下，新建应用执行生成数据库时报错：Invalid model reference 'apps.develop.Event'. String model references must be of the form 'app_label.ModelName'.

报错内容：

 "must be of the form 'app_label.ModelName'." % model
ValueError: Invalid model reference 'apps.develop.Event'. String model references must be of the form 'app_label.ModelName'.

解决方案：

apps.develop.Event   改为：  develop.Event   即可
