Python:2.7; Django:1.7;Mac 10.9.4
在第5章中,本教程讲授如何创建填充脚本,该脚本可以自动为数据库创建一些数据,以便于开发。
我在manage.py的同一级别上创建了populate_rango.py。
这是populate_rango.py:
import os def populate(): python_cat = add_cat('Python') add_page( cat=python_cat, title="Official Python Tutorial", url="http://docs.python.org/2/tutorial/" ) add_page( cat=python_cat, title="How to Think like a Computer Scientist", url="http://www.greenteapress.com/thinkpython/" ) add_page( cat=python_cat, title="Learn Python in 10 Minutes", url="http://www.korokithakis.net/tutorials/python/" ) django_cat = add_cat("Django") add_page( cat=django_cat, title="Official Django Tutorial", url="https://docs.djangoproject.com/en/1.5/intro/tutorial01/" ) add_page( cat=django_cat, title="Django Rocks", url="http://www.djangorocks.com/" ) add_page( cat=django_cat, title="How to Tango with Django", url="http://www.tangowithdjango.com/" ) frame_cat = add_cat("Other Frameworks") add_page( cat=frame_cat, title="Bottle", url="http://bottlepy.org/docs/dev/" ) add_page( cat=frame_cat, title="Flask", url="http://flask.pocoo.org" ) for c in Category.objects.all(): for p in Page.objects.filter(category=c): print "- {0} - {1}".format(str(c), str(p)) def add_page(cat, title, url, views=0): p = Page.objects.get_or_create(category=cat, title=title, url=url, views=views)[0] return p def add_cat(name): c = Category.objects.get_or_create(name=name)[0] return c if __name__ == '__main__': print "Starting Rango population script..." os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tangle.settings') from rango.models import Category, Page populate()
然后,我python populate_rango.py在manage.py级别的终端上运行,将引发AppRegistryNotReady():
python populate_rango.py
django.core.exceptions.AppRegistryNotReady
然后,我用Google搜索了一下,发现像这样:
Standalone scripts¶ If you’re using Django in a plain Python script — rather than a management command — and you rely on the DJANGO_SETTINGS_MODULE environment variable, you must now explicitly initialize Django at the beginning of your script with: >>> import django >>> django.setup() Otherwise, you will hit an AppRegistryNotReady exception.
而且我仍然不知道该怎么办,可以帮忙吗?谢谢!!!
如果你在独立脚本中使用django项目应用程序,换句话说,如果不使用manage.py-你需要先手动调用-你将需要django.setup()配置日志记录,并且重要的是-填充apps注册表。
manage.py
django.setup()
引用初始化过程文档:
设定()
该函数自动被调用:
通过Django的WSGI支持运行HTTP服务器时。
调用管理命令时。
在其他情况下,例如在纯Python脚本中,必须显式调用它。
对于你的情况,你需要setup()手动致电:
setup()
if __name__ == '__main__': print "Starting Rango population script..." os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tangle.settings') import django django.setup() populate()
