Sorted and Translated ActiveRecord Model with Globalize2 and Ruby Magic

This code returns all records of your model sorted by translated field name when using Globalize2 :

app/models/widget.rb def self.all_sorted Widget.find(:all, :joins => :globalize_translations, :conditions => ['locale = ?', I18n.locale]).sort_by(&:name) end

As outlined it this post, :joins => :globalize_translations is mandatory. The unary ampersand operator converts a Proc to a block, so in this case sort_by(&:name) is “shorthand” for

sort {|x,y| x.name <=> y.name}

Ruby sometimes feels like assembling a Swiss watch in code, where other languages feel like fixing an old car.
