You can turn on ActiveRecord store for session. Look in config/initializers/session_store.rb

comment out the line about using :cookie_store

uncomment the lines at the bottom about using :active_record_store

# Use the database for sessions instead of the cookie-based default,
# which shouldn't be used to store highly confidential information
# (create the session table with "rails generate session_migration")
MyApp::Application.config.session_store :active_record_store

Create migration before rails rails g session_migration and migrate it.
