All, I'd like to propose the Object#nonblank? in ActiveSupport, layered over the blank? method. This has been working well for us in the past year and hopefully others will find it useful enough to include in core.
It is analogous to Ruby's Numeric#nonzero? method: it either returns the object itself (if not blank) or nil (if blank). This makes it easy to treat blank parameters the same as missing ones, and allows chaining: For example, this: state = params[:state] unless params[:state].blank? country = params[:country] unless params[:country].blank? region = state || country || 'US' becomes: region = params[:state].nonblank? || params[:country].nonblank? || 'US' The ticket is here: https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/3620-objectnonblank-analogous-to-rubys-numericnonzero#ticket-3620-2 along with a patch that includes full documentation and tests. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
