Rails, ¿cómo determinar si se creó un usuario hoy?

I would like a way to determine if a User record is new or not. Based on where I need to do this in my app, I would like to do this by know if the user was created today or now.

¿Cómo puedo hacer algo como:

if current_user.created_at.today?

Any timezone issues? Maybe it would be better to do, created_at in the last 24 hours?

Muchas Gracias

Is your requirement for the server side to know if it was created today or the user in their local time? Timezone would matter in the later case. -

Prefiero usar current_user.created_at.to_date == Date.current, as it is more self explanatory.

To check if the user was created in the last 24 hours, do something like this:

if current_user.created_at > Time.now - 24.hours
  #...
end

-24.hours isn't going to work as that could take you into yesterday, instead use: Time.now.beginning_of_day - rana gorda

you definitely have several approaches, this is also why I like rails && ruby. Anyway don't forget about Ley de Deméter, hence I will go with the following:

class User
  # ... methods and other active record stuff

  def created_today?
    self.created_at.to_date == Date.today
  end

end

and than you can see if a user is created today with the following api,

 if User.find(params[:id]).created_today?
   #do something...

O...

 scope :today, lambda {
   where('authdate = ?', Date.today )
  }

If your application needs to support time zones:

  • Ensure you have the correct time zone set in config/application.rb: config.time_zone = "Mountain Time (US & Canada)"
  • Access the current time: Time.zone.now
  • Access the name of the default time zone: ActiveSupport::TimeZone[Rails.configuration.time_zone]
  • Retrieve the UTC offset for the default time zone: ActiveSupport::TimeZone[Rails.configuration.time_zone].utc_offset / 1.hour
