I want to run a standalone ruby script in which I need my RoR environment to be used. Specifically, I need my models extending ActionMailer and ActiveRecord. I also need to read the database configuration from my database.yml. How do I go about it?

推荐答案

最简单的方法是从更改脚本的shebang:

The easiest way is to change the shebang of your script from :

#!/usr/bin/ruby

到

#!/path/to/your/rails/script/runner

等等，您的脚本将在完整的Rails环境加载后运行.您还可以将脚本作为./my_script -e production运行，以使其与生产数据库一起运行.

Et voilà, your script will be run with the full rails environment loaded. You can also run your script as ./my_script -e production to have it run with the production database.
