如何在我的模型.py中引用django设置变量?

This is a very beginner question. But I'm stumped. How do I reference a django settings variable in my model.py?

这是一个初学者的问题。但我难住了。如何在模型.py中引用django设置变量?

NameError: name 'PRIVATE_DIR' is not defined Also tried a lot of other stuff including settings.PRIVATE_DIR

NameError:没有定义名称“PRIVATE_DIR”还尝试了许多其他的东西，包括settings.PRIVATE_DIR

What's the correct way to do this?

正确的做法是什么?

---------settings.py-------------

- - - - - - - - - - -settings.py - - - - - - - - - - - - -

PRIVATE_DIR = '/home/me/django_projects/myproject/storage_dir'

---------model.py---------------

- - - - - - - - - - -model.py - - - - - - - - - - - - - - - -

# Problem is here.
from django.core.files.storage import FileSystemStorage

fs = FileSystemStorage(location=PRIVATE_DIR)

class Customer(models.Model): 
    lastName = models.CharField(max_length=20) 
    firstName = models.CharField(max_length=20) 
    image = models.ImageField(storage=fs, upload_to='photos', blank=True, null=True)

Try with this: from django.conf import settings

试试这个:来自django。配置导入设置

#2

from django.conf import settings

PRIVATE_DIR = getattr(settings, "PRIVATE_DIR", None)

Where it says None, you will put a default value incase the variable isn't defined in settings.

如果它说无，则在设置中未定义变量时，将设置一个默认值。
