python - 运行时错误 :App registry isn't ready yet

Question

我正在尝试创建一个脚本，用测试用户填充数据库。我是 Django 和 Python 的新手。我不断得到:

Runtime error: App registry isn't ready yet. 

这是输出和错误:

starting population script
Traceback (most recent call last):
File "populate.py", line 32, in <module>
populate()
File "populate.py", line 22, in populate
i.save()
File "c:\Python27\lib\site-packages\django-1.7a2-py2.7.egg\django\db\models\base.py",    line 603, in save
force_update=force_update, update_fields=update_fields)
...
...
...    
File "c:\Python27\lib\site-packages\django-1.7a2-py2.7.egg\django\apps\registry.py", line   156, in get_models
self.check_ready()
File "c:\Python27\lib\site-packages\django-1.7a2-py2.7.egg\django\apps\registry.py",   line 119, in check_ready
raise RuntimeError("App registry isn't ready yet.")
RuntimeError: App registry isn't ready yet.

代码如下:

import os
import datetime

def populate():
    freer = User.objects.create_user( 'joyyie', 'lolcats@gmail.com', 'e')
    cat = User.objects.create_user( 'steve', 'l2olcats@gmail.com', 'e')
    dog = User.objects.create_user( 'aasd', 'lo3lcats@gmail.com', 'ad')
    cow = User.objects.create_user( 'sadsfa', 'lol4cats@gmail.com', 't' )
    pig = User.objects.create_user( 'regibald', 'lolc5ats@gmail.com', '0')
    donkey = User.objects.create_user( 'turnip', 'lolca6ts@gmail.com', 'pop')
    human = User.objects.create_user( 'tutu', 'lolcat7s@gmail.com', 'pa')
    a = [freer,cat,dog,cow,pig,donkey,human]

    for i in a:
        i.first_name= 'jackee'
        i.is_superuser=True
        i.is_staff=False
        i.date_joined=datetime.datetime.today()
        i.last_login=datetime.datetime.today()

        i.save()


if __name__=='__main__':
    print "starting population script"
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'infosmos.settings')
    from django.conf import settings
    from django.db import models
    from django.contrib.auth.models import User
    populate()

有没有办法通过使用信号或其他方式强制创建用户配置文件以等待注册表应用程序？

[django 1.7] 您希望运行的独立脚本，导入 django 和如下设置

import os

import django

[...]


if __name__ == '__main__':  
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')

    django.setup()
