Django 自定义命令和 cron [英] Django custom command and cron

问题描述

我希望我的自定义 Django 命令每分钟执行一次.然而，python/path/to/project/myapp/manage.py mycommand 似乎在 python manage.py mycommand 目录下似乎不起作用.

I want my custom made Django command to be executed every minute. However it seems like python /path/to/project/myapp/manage.py mycommand doesn't seem to work while at the directory python manage.py mycommand works perfectly.

我怎样才能做到这一点?我使用 /etc/crontab 与:

How can I achieve this ? I use /etc/crontab with:

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

推荐答案

我认为问题在于 cron 将在裸"环境中运行您的脚本，因此您的 DJANGO_SETTINGS_MODULE 可能未定义.您可能希望将其包装在首先定义 DJANGO_SETTINGS_MODULE 的 shell 脚本中

I think the problem is that cron is going to run your scripts in a "bare" environment, so your DJANGO_SETTINGS_MODULE is likely undefined. You may want to wrap this up in a shell script that first defines DJANGO_SETTINGS_MODULE

像这样:

#!/bin/bash

export DJANGO_SETTINGS_MODULE=myproject.settings 
./manage.py mycommand

使其可执行(chmod +x)，然后设置 cron 来运行脚本.

Make it executable (chmod +x) and then set up cron to run the script instead.

编辑

我还想说，您可以稍微模块化"这个概念，并使其脚本接受管理命令作为参数.

I also wanted to say that you can "modularize" this concept a little bit and make it such that your script accepts the manage commands as arguments.

#!/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"或您想要从 cron 作业运行的任何其他 manage.py 命令.

Now, your cron job can simply pass "mycommand" or any other manage.py command you want to run from a cron job.
