如何使用Django中的manage.py列出所有安装的应用程序？

问题描述

一些 manage.py 命令将Django应用程序作为参数。有时我想使用这些命令，但不记得应用程序的名称。有没有办法让manage.py提供一个这样的列表？

Some manage.py commands take Django applications as arguments. Sometimes I want to use these commands, but can't remember the name of the application. Is there a way to get manage.py to provide a such a list?

推荐答案

没有准备好，但你可以管道：

not ready made, but you can pipe:

$ echo 'import settings; settings.INSTALLED_APPS' | ./manage.py shell
...
>>> ('django.contrib.auth', 'django.contrib.contenttypes', 
     'django.contrib.sessions', 'django.contrib.sites'...]

或写一个小的：

import settings
from django.core.management.base import BaseCommand
class Command(BaseCommand):
    def handle(self, *args, **options):
        print settings.INSTALLED_APPS

或以更通用的方式：

import settings
from django.core.management.base import BaseCommand
class Command(BaseCommand):
    def handle(self, *args, **options):
        print vars(settings)[args[0]]

$ ./manage.py get_settings INSTALLED_APPS
('django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 
 'django.contrib.sites', ...]
$ ./manage.py get_settings TIME_ZONE
