Ruby comparing dates
I would like to do is to know if a user has 开发者_如何学Gobeen created in the system in the last 10 second. so i would do:
def new_user
if(DateTime.now - User.created_at < 10)
return true
else
return false
end
end
IT is just an idea , how can i do it correctly? thank you
class User < ActiveRecord::Base
def new?
created_at > 10.seconds.ago
end
end
# Example:
user = User.create!
user.new?
#=> true
sleep 11
user.new?
#=> false
(Presuming your User
class is an ActiveRecord
model.)
User.created_at > 10.seconds.ago
