Django.core.exceptions.improperyconfigured:请求设置日志配置，但未配置设置

Question

我正在尝试运行一个填充脚本，我把它从tango嫒with_Djangotutorial（https://github.com/leifos/tango_with_django/blob/master/tango_with_django_project/populate_rango.py）放在一起，但是我得到了下面的回溯，它似乎与django 1.7中所做的更改有关？如果有人能解释一下我做错了什么，我将不胜感激。

我的populate_clubs.py脚本

import os
import sys
import django
django.setup()


def add_club(name, nickname, manager, established, stadium, active=True):
    c = clubs.objects.get_or_create(name=name, nickname=nickname, manager=manager, established=established, stadium=stadium, active=active)
    return c

def populate():
    add_club(name = "Aston Villa",
        nickname = "Villans",
        manager = "Tim Sherwood",
        established = "1897",
        stadium = "Villa Park"
        )

    # Print out what was added
    for c in clubs.objects.all():
        print "The following has been added to clubs:" + c



# Start execution
if __name__ == '__main__':
    print "Starting club population script..."
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'epl.settings')
    from teams.models import clubs
    populate()

Answer 1

如果通过在终端中运行python来启动与Django的交互后遇到类似错误，则在适当的目录中运行python manage.py shell可能会解决您的问题。

Answer 2

可以在django.setup()行之前插入os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")。

Answer 3

对django.setup的调用应该在设置DJANGO_SETTINGS_MODULE环境变量之后进行。把它移到你的__main__中，就在os.environ.setdefault之后。
