# TODO in rails

Question

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.

Answer 1

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

Answer 2

rake notes:todo

Answer 3

grep -rn "# TODO" .

Answer 4

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

Answer 5

Print all annotations

$ bin/rails notes

app/models/user.rb:
  * [  110] [TODO] Refactor this 

test/test_helper.rb:
  * [   72] [FIXME] Unable to stub this method in the `sign_in` helper

Print specific annotations (FIXME)

$ bin/rails notes -a FIXME

test/test_helper.rb:
  * [ 72] Unable to stub this method in the `sign_in` helper
