J'ai un attribut d'objet de la classe DateTime.
Comment pourrais-je comprendre si la date enregistrée est aujourd'hui, demain ou plus tard?
Voici quelques moyens utiles pour y parvenir:
datetime = DateTime.now => Sun, 26 Oct 2014 21:00:00
datetime.today? # => true
datetime.to_date.past? # => false (only based on date)
datetime.to_date.future? # => false (only based on date)
datetime.to_date == Date.tomorrow # => false
datetime.to_date == Date.yesterday # => false
Quelque chose comme...
datetime = Time.now.to_datetime
=> Sun, 26 Oct 2014 16:24:55 -0600
datetime >= Date.today
=> true
datetime < Date.tomorrow
=> true
datetime += 1.day
=> Mon, 27 Oct 2014 16:25:12 -0600
datetime >= Date.today
=> true
datetime >= Date.tomorrow
=> true
datetime < (Date.tomorrow + 1.day)
=> false
?
