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

问题描述

我想要每分钟执行一次自定义的Django命令。但是似乎 python /path/to/project/myapp/manage.py mycommand 在目录 python manage似乎不工作。 py mycommand 工作完美。

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.

我如何实现这一点？我使用 / etc / crontab ：

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

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

推荐答案

我认为问题是cron要在裸环境中运行你的脚本，所以你的DJANGO_SETTINGS_MODULE很可能未定义。你可能想把它放在一个shell脚本中，首先定义DJANGO_SETTINGS_MODULE

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

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代替运行脚本。

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

编辑

我也想说，你可以模块化这个概念一点点，让它让你的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 或任何其他manage.py命令要从cron作业运行。

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