Why is rake db:migrate:reset not listed in rake -T?
Inside my Rails (3.1.3) application, I can run rake db:test:prepare. But when I run rake -T [db], that task (and many others I can use) does not show up.
在我的 Rails (3.1.3) 应用程序中，我可以运行rake db:test:prepare. 但是当我运行时rake -T [db]，该任务（以及我可以使用的许多其他任务）不会出现。
How do I get a complete list of tasks, or why is it incomplete in the first place?
我如何获得完整的任务列表，或者为什么它首先不完整？
E.g. http://mindspill.net/computing/cross-platform-notes/ruby-on-rails/how-to-list-rake-tasks/shows that the 'db:test:prepare' task got listed for an older Rails version when running rails -T.
例如http://mindspill.net/computing/cross-platform-notes/ruby-on-rails/how-to-list-rake-tasks/显示 'db:test:prepare' 任务已针对较旧的 Rails 列出运行时的版本rails -T。

I found at Why is rake db:migrate:reset not listed in rake -T?(thanks @Beerlington for the link) that rake -Plists all tasks, which is what I was looking for.
我在为什么 rake db:migrate:reset 未在 rake -T 中列出？（感谢@Beerlington 提供链接）rake -P列出了所有任务，这正是我要找的。

Only tasks with descriptions set will appear in rake -T.
只有设置了描述的任务才会出现在 中rake -T。
As for why not all tasks have descriptions.... that I don't know.
至于为什么不是所有的任务都有描述……我不知道。
