Things you take for granted after using Ruby for awhile:
#This works: topic.posts.length > 0 #The Ruby way: topic.posts.any? #This works: topic.posts[topic.posts.length-1] #The Ruby way: topic.posts.last #This works: if!((foo != nil)&&(foo != '')) #The Ruby way: unless foo.blank?
Other nice things that I don’t care to come up with the harder version by hand for:
note: day.* and .blank? only works in rails, not ruby out the box
