Django get_model（）导致错误：无法导入名称设置

更新：

Traceback (most recent call last):
  File ".../actstream/settings.py", line 7, in <module>
    MODELS[model.lower()] = model = get_model(*model.split('.'))
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 213, in get_model
    self._populate()
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 67, in _populate
    self.load_app(app_name)
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 88, in load_app
    models = import_module('.models', app_name)
  File ".../lib/python2.7/site-packages/django/utils/importlib.py", line 35, in import_module
    __import__(name)
  File ".../libs/actstream/models.py", line 12, in <module>
    from actstream import managers, settings as actstream_settings
ImportError: cannot import name settings

我尝试将

从actstream导入设置修改为actstream\u设置

到

将actstream.settings导入为actstream\u设置

，它告诉我：

AttributeError: 'module' object has no attribute 'settings'

actstream

应用程序中的

\uuuuu init\uuuuuuuuuuuuuuuuuuuuuuuuuuuuupy

文件不是空的，这可能是它无法将

actstream/settings.py

导入为

actstream.settings

的原因吗

原始问题：

Traceback (most recent call last):
  File ".../actstream/settings.py", line 7, in <module>
    MODELS[model.lower()] = model = get_model(*model.split('.'))
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 213, in get_model
    self._populate()
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 67, in _populate
    self.load_app(app_name)
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 88, in load_app
    models = import_module('.models', app_name)
  File ".../lib/python2.7/site-packages/django/utils/importlib.py", line 35, in import_module
    __import__(name)
  File ".../libs/actstream/models.py", line 12, in <module>
    from actstream import managers, settings as actstream_settings
ImportError: cannot import name settings

我有一个正在工作的django项目。我从trunk安装了以下应用程序

actstream

，因为最新版本有错误：

将此应用加载到我的项目时，会引发以下异常：

Error: cannot import name settings

我已经验证了错误发生在

actstream/settings.py

中的第一个命令

get_model（）

中，如下所示：

from django.conf import settings
from django.db.models import get_model
import sys

MODELS = {}
for model in getattr(settings, 'ACTSTREAM_ACTION_MODELS', ('auth.User',)):
    MODELS[model.lower()] = model = get_model(*model.split('.'))

MANAGER_MODULE = getattr(settings, 'ACTSTREAM_MANAGER',
    'actstream.managers.ActionManager')
a, j = MANAGER_MODULE.split('.'), lambda l: '.'.join(l)
MANAGER_MODULE = getattr(__import__(j(a[:-1]), {}, {}, [a[-1]]), a[-1])

USE_JSONFIELD = getattr(settings, 'ACTSTREAM_USE_JSONFIELD', False)

在这个例子中，

get\u model（）

为什么会抛出一个关于无法加载

设置的错误

回溯：

Traceback (most recent call last):
  File ".../actstream/settings.py", line 7, in <module>
    MODELS[model.lower()] = model = get_model(*model.split('.'))
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 213, in get_model
    self._populate()
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 67, in _populate
    self.load_app(app_name)
  File ".../lib/python2.7/site-packages/django/db/models/loading.py", line 88, in load_app
    models = import_module('.models', app_name)
  File ".../lib/python2.7/site-packages/django/utils/importlib.py", line 35, in import_module
    __import__(name)
  File ".../libs/actstream/models.py", line 12, in <module>
    from actstream import managers, settings as actstream_settings
ImportError: cannot import name settings

回溯（最近一次呼叫最后一次）：
文件“../actstream/settings.py”，第7行，在
MODELS[model.lower（）]=model=get_model（*model.split（'.'））
文件“../lib/python2.7/site packages/django/db/models/load.py”，第213行，在get_模型中
自我.()
文件“../lib/python2.7/site packages/django/db/models/load.py”，第67行，在
自加载应用程序（应用程序名称）
文件“../lib/python2.7/site packages/django/db/models/load.py”，第88行，在load_应用程序中
模型=导入模块（'.models'，应用程序名称）
文件“../lib/python2.7/site packages/django/utils/importlib.py”，第35行，在导入模块中
__导入（名称）
文件“../libs/actstream/models.py”，第12行，在
从actstream导入管理器中，设置为actstream\u设置
导入错误：无法导入名称设置

现在我注意到models.py中发生了导入错误，但我仍然不明白它如何无法将settings.py文件导入为actstream.settings。
请发布完整的回溯？添加了回溯。我不明白导入语句是如何失败的。这似乎是由循环导入引起的
settings.py
通过get_model（）函数导入
models.py
，然后再次导入
settings.py
