为什么我需要设置DJANGO_SETTINGS_MODULE？ [英] Why do I need the DJANGO_SETTINGS_MODULE set?

问题描述

每次通过SSH登录我的服务器时，我需要键入以下内容：

Every time I log on to my server through SSH I need to type the following:

export DJANGO_SETTINGS_MODULE=settings

如果我没有使用manage.py模块失败

if I do not any usage of the manage.py module fails

我的manage.py有以下添加的代码：

My manage.py has the following added code:

if "notification" in settings.INSTALLED_APPS:
    from notification import models as notification

    def create_notice_types(app, created_models, verbosity, **kwargs):
        notification.create_notice_type("friends_invite", _("Invitation Received"), _("you have received an invitation"))
        notification.create_notice_type("friends_accept", _("Acceptance Received"), _("an invitation you sent has been accepted"))

    signals.post_syncdb.connect(create_notice_types, sender=notification)
else:
    print "Skipping creation of NoticeTypes as notification app not found"

任何想法？

推荐答案

您的 manage.py 正在引用一个应用程序（ notifications ）。由于Django环境尚未设置，Django会抱怨DJANGO_SETTINGS_MODULE被设置。

Yourmanage.py is referencing an application (notifications). This forces Django to complain about DJANGO_SETTINGS_MODULE being set because the Django environment hasn't been set up yet.

顺便说一下，您可以手动强制环境设置，但是老实说，我会不要在manage.py中执行此操作。这在我看来并不是一个很好的做法。

Incidentally, you can force the enviroment setup manually, but honestly I wouldn't do this in manage.py. That's not really a good practice in my opinion.

以下是您可以从任何应用程序（或程序中）手动设置Django环境：

Here is how you can manually setup the Django environment from within any app (or program for that matter):

# set up the environment using the settings module
from django.core.management import setup_environ
from myapp import settings
setup_environ(settings)
