Object methods for rails (presence)
Returns the receiver if it's present otherwise returns nil. object.presence is equivalent to

object.present? ? object : nil
For example, something like

state = params[:state] if params[:state].present?
country = params[:country] if params[:country].present?
region = state || country || 'US'
becomes

region = params[:state].presence || params[:country].presence || 'US'

The presence method returns its receiver if present?, and nil otherwise. It is useful for idioms like this:

host = config[:host].presence || 'localhost'
