我希望我的自定义Django命令每分钟执行一次。但是，似乎python /path/to/project/myapp/manage.py mycommand在目录下python manage.py mycommand工作正常时似乎不起作用。

我该如何实现？我使用/etc/crontab：

****** root python /path/to/project/myapp/manage.py mycommand

我认为问题在于cron将在“裸机”环境中运行脚本，因此您的DJANGO_SETTINGS_MODULE可能未定义。您可能需要将其包装在首先定义DJANGO_SETTINGS_MODULE的shell脚本中

像这样：

!/bin/bash

export DJANGO_SETTINGS_MODULE=myproject.settings

./manage.py mycommand

使它可执行（chmod + x），然后设置cron来运行脚本。

编辑

我也想说的是，您可以稍微“模块化”这个概念，并使您的脚本接受manage命令作为参数。

!/bin/bash

export DJANGO_SETTINGS_MODULE=myproject.settings

./manage.py ${*}

现在，您的cron作业可以简单地传递“ mycommand”或您要从cron作业运行的任何其他manage.py命令。

这是我执行时说的未知命令。我必须将其更改为：cd / path / to / project ./manage.py $ {*} – mhost 10年 2月21日，19：27

没有成功可以识别自定义命令，但该命令显然找不到数据库 – Raphael 2011年 9月15日，18：57

您“命令显然找不到数据库”是什么意思？这会带来某种错误吗？ – Joe Holloway 2011年9月16日19:48

如果您希望Django的生活更加简单，请在项目中使用django-command-extensions：

http://code.google.com/p/django-command-extensions/

您将找到一个名为“ runscript”的命令，因此只需将命令添加到crontab行中：

* root python /path/to/project/myapp/manage.py runscript mycommand

这样的脚本将在Django上下文环境中执行。

The runscript extension wasn’t well documented. Unlike the django command this one can go anywhere in your project and requires a scripts folder. The .py file requires a run() function.

cd /path/to/project/myapp && python manage.py mycommand

By chaining your commands like this, python will not be executed unless cd correctly changes the directory.

This was the easiest way to do it for me and it worked well. Thanks David! – thomallen Apr 6 ‘11 at 23:55

that didn’t work for me (still having a No module named django.core.management error in my mails) – Guillaume Gendre Apr 30 ‘12 at 15:32

If its a standalone script, you need to do this:

from django.conf import settings

from django.core.management import setup_environ

setup_environ(settings)

your code here which uses django code, like django model

If its a django command, its easier: https://coderwall.com/p/k5p6ag

In (management/commands/exporter.py)

from django.core.management.base import BaseCommand, CommandError

class Command(BaseCommand):

args = ‘’

help = ‘Export data to remote server’

def handle(self, *args, **options):
    # do something here

And then, in the command line:

$ python manage.py exporter

Now, it’s easy to add a new cron task to a Linux system, using crontab:

$ crontab -e

or $ sudo crontab -e if you need root privileges

In the crontab file, for example for run this command every 15 minutes, something like this:

m h dom mon dow command

/15 * * * python /var/www/myapp/manage.py exporter
