でも、実際は rake db:migrate:reset など、他にもコマンドがあるんですが、この中には載ってないようです。。。。。
全部観たい！！と思ってたのですが、よく調べ方がわかりませんでした。。。
description が載っていないのでよければ、以下のコマンドで調べれらます。
$ rake -P | grep rake rake about rake assets:clean rake assets:clean:all rake assets:environment rake assets:precompile rake assets:precompile:all rake assets:precompile:nondigest rake assets:precompile:primary rake db:_dump rake db:abort_if_pending_migrations rake db:charset rake db:collation rake db:create rake db:create:all rake db:drop rake db:drop:all rake db:fixtures:identify rake db:fixtures:load rake db:forward rake db:load_config rake db:migrate rake db:migrate:down rake db:migrate:redo rake db:migrate:reset rake db:migrate:status rake db:migrate:up rake db:reset rake db:rollback rake db:schema:dump rake db:schema:load rake db:schema:load_if_ruby rake db:seed rake db:sessions:clear rake db:sessions:create rake db:setup rake db:structure:dump rake db:structure:load rake db:structure:load_if_sql rake db:test:clone rake db:test:clone_structure rake db:test:load rake db:test:load_schema rake db:test:load_structure rake db:test:prepare rake db:test:purge rake db:version rake default rake doc rake doc/api rake doc/api/index.html rake doc/app rake doc/app/index.html rake doc:app rake doc:clobber rake doc:clobber_app rake doc:clobber_plugins rake doc:clobber_rails rake doc:guides rake doc:plugins rake doc:rails rake doc:reapp rake doc:rerails rake environment rake log:clear rake middleware rake notes rake notes:custom rake notes:fixme rake notes:optimize rake notes:todo rake rails:template rake rails:templates:copy rake rails:update rake rails:update:application_controller rake rails:update:configs rake rails:update:scripts rake rails_env rake railties:install:migrations rake routes rake secret rake stats rake test rake test:benchmark rake test:functionals rake test:integration rake test:plugins rake test:prepare rake test:profile rake test:recent rake test:run rake test:single rake test:uncommitted rake test:units rake time:zones:all rake time:zones:local rake time:zones:us rake tmp:cache:clear rake tmp:clear rake tmp:create rake tmp:pids:clear rake tmp:sessions:clear rake tmp:sockets:clear
こんな感じですね。
ちなみに Rails 3.2.9 です。どっかのバージョンでは、rake -T で全部見れたらしいのですが。。いちおうそれが載ってる記事があったので、紹介します。
[ rake --helpとrake -Tの実行結果 ]
以上〜。
