运行时错误：应用程序注册表尚未就绪

Question

我试图创建一个脚本，用测试用户填充数据库。我不熟悉Django和Python。我不断得到：

Runtime error: App registry isn't ready yet. 

以下是输出和错误：

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.

下面是代码：

import os
import datetime

def populate():
    freer = User.objects.create_user( 'joyyie', '[e-mail]', 'e')
    cat = User.objects.create_user( 'steve', '[e-mail]', 'e')
    dog = User.objects.create_user( 'aasd', '[e-mail]', 'ad')
    cow = User.objects.create_user( 'sadsfa', '[e-mail]', 't' )
    pig = User.objects.create_user( 'regibald', '[e-mail]', '0')
    donkey = User.objects.create_user( 'turnip', '[e-mail]', 'pop')
    human = User.objects.create_user( 'tutu', '[e-mail]', '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用户配置文件创建等待注册表应用程序？

Answer 1

我发现，如果我运行填充通过manage.pyshell与可执行文件（）命令，然后它运行正常。在我开始修改数据库或运行外部代码之前，一切都需要设置。谢谢Lanzz的提示。

Answer 2

根据Django的1.7发行说明，在“启动顺序”条款下，这是一种已知和预期的行为：

另一个常见的罪魁祸首是django.contrib.auth.get_user_model（）。使用AUTH_USER_MODEL设置在导入时引用User模型。

这就应该奏效了

供参考：https://docs.djangoproject.com/en/dev/releases/1.7/#app-loading-changes

Answer 3

import os

import django

[...]


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

    django.setup()
