How to use django_crontab with os.environ['SECRET_KEY']?

由 假如想象 提交于 2021-02-11 12:50:19
问题 I'm using a django_crontab library and it worked fine until I decided to export my SECRET_KEY to an environmental variable. Summing up what I have done in bash (while in my venv): export SECRET_KEY='some_secret_key_from_settings' In settings.py: SECRET_KEY = os.environ['SECRET_KEY'] In addition, I use venv, so I've also added this to settings: CRONTAB_PYTHON_EXECUTABLE = '/path_to_my_venv/venv/bin/python3' This is the error that I have: SECRET_KEY = os.environ['SECRET_KEY'] File "/Library

Initialize WordPress environment in a script to be run by a cron job

由 ℡╲_俬逩灬. 提交于 2021-02-10 20:36:27
问题 I have to run a custom PHP script which I want to run by a cron job. Within that script, I need wordpress functions to insert users into WordPress table. My script is on the root directory of the wordpress installation. My script is starting with: require( dirname( __FILE__ ) . '/wp-load.php' ); If I run the script directly in the browser then my functions and everything else works with no errors. But when the cron hits it apparently does not work. Nothing that is supposed to happen happens.

Linux学习记录 别出心裁的Linux命令学习法 学习总结 (由于我的电脑是Mac，Linux安装省略) 操作系统的功能： 管家婆 和 服务生 博客中对于这两个词含义的解释为 管家婆：通过进程、虚拟内存和文件三个重要抽象管理计算机的CPU、内存、I/O设备。 服务生：为用户提供shell,为程序员提供系统调用。 命令行的好处 主要是可以批处理并自动化，还有些功能GUI无法完成 由于我的电脑操作系统为MacOS，所以我自己总结出了快捷键的使用： Alt+Ctrl+T :打开终端（由于Mac没有打开终端的快捷键，所以我自己设置为与Ubuntu统一的快捷键。 Mac如何设置打开终端的快捷键 ) Command+T :新建标签页 Command + { 或 Command + Shift + [ :切换标签页 Tab :命令、文件名等自动补全功能。 Ctrl+R :快速检索使用过的历史命令 Ctrl+C :中断终端中正在执行的任务。 Linux基础入门 实验1 Linux 系统简介 Linux是什么？ Linux 就是一个<span style="color:red">操作系统</span>。Linux 主要是 系统调用 和 内核 那两层。当然直观地看，我们使用的操作系统还包含一些在其上运行的应用程序，比如文本编辑器、浏览器、电子邮件等。 Shell是什么？ 命令行解释器。 实验2
