将Rails cookie设置为在1天后过期

Question

Looking through the docs here http://api.rubyonrails.org/classes/ActionDispatch/Cookies.html , and setting a Rails cookie as follows:

cookies[:votes_left] = { :value => 3, :expires => 24.hours.from_now }

Inside my browser (Chrome), it's reporting the correct value but is giving me Invalid Date under the Expires column (Network > Cookies).

Am I setting the date incorrectly? I've tried variations on the Time object, but keep getting the same result, a correctly valued cookie with an invalid expiration .

Answer 1

Tested this out myself and I see no issue with your code. As @Nevir said, check whether your server clock is correct. The only issue with that, if it's the wrong server time and it's actually setting the expiration before today's date, it won't set the cookie.

Try adding Rails.logger 24.hours.from_now just to see what it outputs.

But yes, you are setting the expires parameter properly.
