Hey all, Out of curiousity, all in Rails grabs all the records and converts them into an array. Map then iterates through the returned array, returning a new array. So why even use map here? And then the array gets passed as local variable bt. And we instantiate object and assign the bt array as a value of a hash of book_type. I dont see why map is needed here.
book_details = BookType.all.map do |bt| Student.new(:book_type => bt) end Thanks for response. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
