# 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 and 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

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" .

rake notes:todo
