this explains what ".reject" does: http://ruby-doc.org/core/classes/Enumerable.html#M003126 So essentially, the line takes the collection of questions that self has, and gets rid of those that are nil (fairly self-explanatory if you just read the line out loud to yourself ;-) TBH, I think the "all" at the end is a syntax error - Array doesn't have a .all method, although I'm not at a Ruby console to check. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
