Ruby on Rails global array

Question

I want to instantiate an array that is accesible trough all the application, the array may change while the application is running but it will be re-generated when the application starts again.

I have though about putting that array in the ApplicationController but it will die once the request is over or not ?; and I just need it to populate it once every time the app starts running not every time a controller action is called.

The array is populated from the database and that has to be already loaded.

Thanks in advance for any guidance.

Answer 1

Create a file inside you config/initializers called whatever-you-want.rb and place you code there.

THIS_IS_AN_ARRAY = [1,2,3,4]

You should then be able to access THIS_IS_AN_ARRAY all over your application.
