This is for anyone that cares about how long a user is signed
in:
Currently I have a user to be signed in forever unless they
log out (cookies.permanent....).
If you want to change that, change line 7 to this:
cookies[:remember_token] = { value: remember_token,
expires: 20.years.from_now.utc }
which will expire the cookie in 20 years from its date of
creation.
Oddly enough, this line above is equivalent to the:
cookies.permanent
This is just a short cut for this line since most people
create permanent cookies these days.
Other times are:
10.weeks.from_now
5.days.ago
etc...
