Sessions

Store session in database

• Session data is stored in DB

• config/initializers/session_store.rb

Rails.application.config.session_store :active_record_store

• use gem 'activerecord-session_store'

# Gemfile
gem 'activerecord-session_store', github: 'rails/activerecord-session_store'

• table in database can be created with rake command:

rails g active_record:session_migration

rake db:migrate

which will create table 'sessions'.

Store session in Redis

as alternative we can store session data in Redis.
