Question

Currently this is helper for getting a datetime selector in a form.

I want to improve it by showing only the next 14 days as options. Is this possible?

Thanks in advance!

  def begins_at_for form
    options = {
      :start_year => Time.now.utc.year,
      :end_year => Time.now.utc.year,
      :discard_year => true,
      :default => 3.days.from_now,
      :use_short_month => true,
      :minute_step => 15,
      :include_seconds => false
    }

    if Time.now.utc.yday > 300
      options.merge!( :end_year => Time.now.utc.year + 1 )
    end
    form.datetime_select(
      :begins_at,
      options
    )
  end

Use jquery and this datepicker. You can disable days on the calendar, so you could disable all but the next 14 days to do what you want.
