# TODO in rails

I had read through a rails book and once found we can add # TODO: and some # stuff in codes, so we can you some rake cmd to look back.

My problems is I can't find where are those "# stuff" and "rake cmd" I google an开发者_开发知识库d search around, but can't find and don't know what keywords to search.

You can use # TODO, # FIXME, and # OPTIMIZE and you can easily get all of these with the following rake task: rake notes

In addition to the default annotations, you can always specify and search for your own annotations:

rake notes:custom ANNOTATION=ZOMG

---

rake notes:todo

---

btw, you need to run that command from the root dir of your rails app. Also, you can run:

rake -T

to get a full list of the tasks in your rails' Rakefile

---

grep -rn "# TODO" .
