ruby - How to store the flash in a different cookie to the Rails session? -


we have rails session cookie set visible on subdomain issued (i.e. setting domain: nil in session store configuration). means there separate user sessions per subdomain, want.

however, still flash messages visible across subdomains. if log out on foo.oursite.com , redirected www.oursite.com, should see "logged out successfully" message flash, despite being different subdomains.

so question is: can configure rails flash system use separate cookie session store, can set domain: :all cookie , have flash visible across subdomains?

(we on rails 5.0)

you e

yourapp::application.config.session_store :cookie_store, key: '_yourapp_session', :domain => :all

but mean cookies accessible across sub-domains , share logged in session cookie.

you maybe want storing alerts in database , retrieve them needed.
