Question

我正在尝试为我在不同应用中定义的所有模型添加基类。我创建了一个包lib/base.py：

from django.db import models
import logging

# Get an instance of a logger
logger = logging.getLogger(__name__)

class Base(models.Model):

class Meta:
        abstract = True

现在在不同的家庭应用目录中，我想使用这个基本模型：

from django.db import models
from libs.base import Base
# Create your models here.
class Home(Base):
    msg = models.CharField(max_length=100)

    @classmethod
    def create(cls, msg):
        home = cls(msg=msg)
        # do something with the book
        return home

当我运行服务器时，出现以下错误：

 File "/Users/.../home/models.py", line 2, in <module>
    from libs.base import Base
ImportError: No module named libs.base

我找不到我在这里缺少的东西？

您应该将libs模块附加到项目的已安装应用中：

settings.py:

...
INSTALLED_APPS = (
    ...
    'home',
    ...
    'libs', # Add this!
)
...
