为什么我在Django中没有导入错误？

import os 
import sys 

os.environ['DJANGO_SETTINGS_MODULE'] = "trade.settings" 
from trade.turkey.models import * 


d = DemoRecs.objects.all() 
d.delete()

当我运行这个，它会导入罚款，如果我离开了d.delete()线。这是错误的。为什么？如果我评论一下，一切都很酷。我可以插入。我可以更新。但是，当我有这条线时，一切都搞砸了。为什么我在Django中没有导入错误？

回溯是：

d.delete() 
    File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 447, in delete 
    obj._collect_sub_objects(seen_objs) 
    File "/usr/local/lib/python2.6/dist-packages/django/db/models/base.py", line 585, in _collect_sub_objects 
    for related in self._meta.get_all_related_objects(): 
    File "/usr/local/lib/python2.6/dist-packages/django/db/models/options.py", line 347, in get_all_related_objects 
    self._fill_related_objects_cache() 
    File "/usr/local/lib/python2.6/dist-packages/django/db/models/options.py", line 374, in _fill_related_objects_cache 
    for klass in get_models(): 
    File "/usr/local/lib/python2.6/dist-packages/django/db/models/loading.py", line 167, in get_models 
    self._populate() 
    File "/usr/local/lib/python2.6/dist-packages/django/db/models/loading.py", line 61, in _populate 
    self.load_app(app_name, True) 
    File "/usr/local/lib/python2.6/dist-packages/django/db/models/loading.py", line 76, in load_app 
    app_module = import_module(app_name) 
    File "/usr/local/lib/python2.6/dist-packages/django/utils/importlib.py", line 35, in import_module 
    __import__(name) 
ImportError: No module named turkey

为trade项目目录将从sys.path丢失。

但我可以插入的东西进去。（它实际上填充数据库）。我也可以选择。 – TIMEX 2011-01-29 01:39:56

为什么？ – 2011-01-29 01:45:35

尝试增加 “贸易” 到PYTHONPATH ...

import os.path 
_pypath = os.path.realpath(os.path.dirname(__file__) + '/trade') 
sys.path.append(_pypath)
