How do I set a Rails cookie to start and/or expire at a certain date?
Excerpts from Rails 5 documentation:
Cookies are read and written through ActionController#cookies.
The cookies being read are the ones received along with the request, the cookies being written will be sent out with the response. Reading a cookie does not get the cookie object itself back, just the value it holds.
Examples of writing:
# Sets a simple session cookie. # This cookie will be deleted when the user's browser is closed. cookies[:user_name] = "david" # Sets a cookie that expires in 1 hour. cookies[:login] = { value: "XJ-122", expires: 1.hour } # Sets a cookie that expires at a specific time. cookies[:login] = { value: "XJ-122", expires: Time.utc(2020, 10, 15, 5) } # Sets a "permanent" cookie (which expires in 20 years from now). cookies.permanent[:login] = "XJ-122"
[...]
The option symbols for setting cookies are:
:expires
- The time at which this cookie expires, as a Time or ActiveSupport::Duration object.[...]
