我需要从Django shell执行Python脚本.我试过了:

./manage.py shell << my_script.py

但它没有用.它只是在等我写点什么.

我试图从另一个python脚本访问我的Django(v1.10)应用程序数据库,并遇到一些麻烦.

这是我的文件和文件夹结构:

store
 store
   __init.py__
   settings.py
   urls.py
   wsgi.py
 store_app
   __init.py__
   admin.py
   apps.py
   models.py
   ...
 db.sqlite3
 manage.py

other_script.py

根据Django的文档,我other_script.py看起来像这样:

import django
from django.conf import settings

settings.configure(DEBUG=True)
django.setup()

from store.store_app.models import MyModel

但它会生成运行时错误:

RunTimeError: Model class store.store_app.models.MyModel doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

我应该注意到我的INSTALLED_APPS列表包含store_app最后一个元素.

如果相反,我尝试传递这样的配置:

import django
from django.conf import settings
from store.store_app.apps import StoreAppConfig

settings.configure(StoreAppConfig, DEBUG=True)
django.setup()

from store.store_app.models import MyModel

我明白了:

AttributeError: type object 'StoreAppConfig has …

注意settings/dev.py代替一个settings.py文件和以下Django(1.4.3)项目script.py中的my_appin:

.
??? my_project
?   ??? my_app
?   ?   ??? __init__.py
?   ?   ??? models.py
?   ?   ??? tests.py
?   ?   ??? views.py
?   ?   ??? script.py
?   ??? __init__.py
?   ??? settings
?   ?   ??? dev.py
?   ?   ??? __init__.py
?   ?   ??? prod.py
?   ??? urls.py
?   ??? wsgi.py
??? manage.py
??? requirements.txt

当我只有一个settings.py文件代替settings文件夹时,我能够运行以下脚本而没有任何错误:

script.py:
