Iterate without an explicit block idiom

Question

In my code, I have an array of ActiveRecord::Base objects, and to save them, for example, I would do something like this:

obj_list = [ar_obj1, ar_obj2, ar_obj3]
obj_list.each { |obj| obj.save! }

It would perhaps be nice and DRY to say instead:

obj_list.each.save!

However, I cannot see how to do this.

It might be a good idea to wrap the `save!` calls in a transaction. — Stefan, Oct 02 '13 at 06:44

You can use Symbol#to_proc shortcut here. But it's still a block, only hidden.

obj_list.each(&:save!)

Thanks - that is just what I was looking for! I think it is more readable in that form for casual readers. – Ken Y-N Oct 02 '13 at 06:44
