blank?()
click to toggle source
An object is blank if it's false, empty, or a whitespace string. For example, false
, '', ' ', nil
, [], and {} are all blank.
This simplifies
!address || address.empty?
to
address.blank?

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'
