Need help understanding how to limit a function to a tree

Need help understanding how to limit a function to a tree

[mediapathic steen]

I have a subtree that contains a daily list of things to do (which I keep as TODOs rather than checklist form for more granular time tracking). I want to reset all of the DONE to TODO every day when I start it. Right now I have this piece of code I copypasted from somewhere now lost (possibly this very group):

(org-map-entries (lambda ()
          (when
              (string=
               (nth 2 (org-heading-components)) "DONE")
               (org-todo "TODO"))))

This more or less makes sense to me. I have this code sitting in the subtree, and  in order to do my daily reset, I edit the subtree in an indirect buffer, eval-region the code, then kill the buffer. 

What I would like to accomplish: 
1) Can you help me understand how to modify this code so that it only applies to the subtree it's run in (parents also would be fine in this case but not necessary and seems more of a challenge)? Doing the indirect buffer thing seems more hassle than is reasonable. 

2) I think I understand how to put this in my init in such a way that I can C-x invoke it, rather than having to eval-region it, but I'm not certain. Can you point me toward a reasonable tutorial or hints on how to do that in general?

Thanks in advance,

You probably want this:

#+BEGIN_SRC emacs-lisp
(defun my-redo ()
  (interactive)
  (org-map-entries
   (lambda ()
     (org-todo "TODO"))
   "TODO=\"DONE\""  ;; the match argument
   'tree))  ;; the scope
#+END_SRC

Then call:

M-x my-redo

in the tree you want to reset.

This worked a treat, and I learned a bit more. Thanks so much!
