What does session_store.rb do?

Question

Hi everybody
I don't understand the usefulness of the session_store.rb file, I tried to read some docs, but I still don't understand, for example, why should I edit that file?

Answer 1

You can change the underlying mechanism of your Session store:

Default is using cookie_store:

Yourapp::Application.config.session_store :cookie_store, key: '_yourapp_session'

However, you can change it to use ActiveRecord, meaning your DB:

Yourapp::Application.config.session_store :active_record_store

Read the Session section of the following tutorial:
