我对我的代码做了一些更改，添加了一个模型，并添加了一些导入，现在突然间，当我试图运行一些管理风格的命令时，我已经编写了脚本，它们失败了，下面是跟踪:

我试过在job .py文件(定义命令行命令)，views.py, admin .py和crrs.py模块中添加try/except块，该模块具有我试图运行的功能。当我尝试/将它们全部取出时，脚本工作但失败，因为模型没有在任何地方定义。
同样，当我使用shell_plus并直接导入作业文件或crrs文件时，我可以执行我想要的函数而不会出现任何错误。我已经遍历了两次提交之间更改的所有代码，没有明显的原因导致这个问题。
任何见解将不胜感激!
Company模型通过一系列导入依赖于url .py，而url .py又依赖于admin.py，而admin.py又依赖于Company。所以你有一个循环导入
我建议尝试通过注释admin.autodiscover()来解决这个问题，但是显示你的django版本将有助于确定这是否真的是罪魁祸首。
如果Django的版本是<仍然推荐使用autodiscover()。接下来要检查的是django-debug-toolbar自动补丁是否有问题，请查看安装说明，特别是"WARNING…">
