Hi there, I've been investigating the railscasts episodes which talk about complex forms and I ran across this notation in the example code provided in part 3 of the episode.
at some point in a model method, there is this line: tasks.reject(&:new_record?).each do |task| I have no problem with the ".each do..." stuff, I guess that "reject" is quite the opposite of find but I quite don't understand the "&:new_record?" notation What is the purpose of the & Is it some sort of Ruby idiom I have the feeling that it should read "find any task object that is not new" (i.e. created but not saved) How would you customize it to achieve this goal : Find the last task object (sorted by id's) that is not new Thanks a lot in advance Christophe -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
