运行 manage.py 命令时如何解决回溯问题？

Question

我对 Django 很陌生，我只是跟着教程一起学习。 我正在从https://github.com/justdjango/getting-started-with-django制作一个项目，在我添加用户和超级用户后，我开始得到这样的回溯：

Traceback (most recent call last):
  File "C:\Users\Dell\Desktop\prog\programa\lib\site-packages\django\contrib\auth\__init__.py", line 160, in get_user_model
    return django_apps.get_model(settings.AUTH_USER_MODEL, require_ready=False)
  File "C:\Users\Dell\Desktop\prog\programa\lib\site-packages\django\apps\registry.py", line 204, in get_model    
    app_label, model_name = app_label.split('.')
ValueError: not enough values to unpack (expected 2, got 1)

During handling of the above exception, another exception occurred:

Answer 1

您忘记在AUTH_USER_MODEL设置中指定模型名称。 如果您在leads应用程序中定义了模型User ，则可以将其设置为：

# settings.py

#           app name ↓
AUTH_USER_MODEL = 'leads.User'
#              model name ↑
