Preserving Rails 4 Devise Session Id Before & After Sign In -

i'm trying implement e-commerce app. in it, allow user browse products , put them cart before signing in. prompt user sign in upon checkout.

however, i'm losing track of user because user's session id changes upon sign in. due this, im unable associate items user placed cart (stored in redis) user placed them in after user signs in application.

does have idea how circumvented?

thanks.

cheers!

found solution. needs done set session.options[:renew] = false , session id still same before & after signing in.

please refer implementation below

class sessionscontroller < devise::sessionscontroller   respond_to :json    def create     super     session.options[:renew] = false   end    def destroy     logger.info "logging out: #{current_user.email}; session id: #{session.id}"     $redis.del "cart_#{session.id}"     super   end  end
