Should you use global variables in Rails?

Question

API

Hey! I have a Rails application. I also have a list of countries that are taken using the VK API. Storing them in a database is kind of silly. Asking every time is also not cool. So the idea came up to store the list in global variables, executing the request only at the time the server starts.
Can you please tell me the best way to organize such an action?

Answer 1

redis? such techniques do not scale well

Actually, not much different from global variables, but more flexible and looks more logical. Plus, most likely something like this will come in handy anyway.

Answer 3

Write a module and store data in it like in a singleton

Answer 4

It must be stored in the database. Stupid to store in global variables and load at server start
