Question

当我尝试将我的models.py文件导入views.py或我的App目录中的其他任何python脚本时，我一直收到此错误，

我在settings.py中有SECRET_KEY，并且还在INSTALLED_APPS列表中添加了应用，

wsgi.py包含

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'projectname.settings')  # I replaced my project name

manage.py还包含

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'projectname.settings')

我已经检查了StackOverflow帖子中其他人的安装。我的代码有效，但是导入模型会破坏它

我使用此命令导入我的课程

from app_name.models import subscribers

并因此定义了订阅者

  class subscribers(models.Model):
    name = models.CharField('Name', max_length=120)
    email = models.CharField('Email', max_length=120)
    access_token = models.TextField()
    expires_in = models.DateTimeField('token expiry date')

我已经执行了makemigrations和migration命令，但是作为一个新手，我不知道该去哪里。请保存一个已经3天的灵魂

谢谢。

下面是我的设置。py

Answer 1

看起来是以下导入导致了该问题：

from oauth_outlook.views import gettoken

在设置中导入视图或模型可能导致循环导入，即使设置了SECRET_KEY错误消息也是如此。我不喜欢django-lockout鼓励您为LOCKDOWN_VIEW_EXCEPTIONS设置导入视图的方式。

我建议您改为设置LOCKDOWN_URL_EXCEPTIONS，这样就不需要导入。

LOCKDOWN_URL_EXCEPTIONS = (
    r'^gettoken$',   # replace with gettoken view
)

SECRET_KEY设置不能为空-即使在settings.py中设置了SECRET_KEY
