Rails 3.1 engines migrations are not working

I'm creating a rails 3.1 engine with migrations. rake db:migration works fine inside that engine, and inside host app. But I need to include this engine into another rails engine. The second engine contains dummy app for testing, I added to application.rb of that dummy app this line:

require 'my_engine'


In the console, I can see classes from the first engine.

rake -T


give me app:my_engine_engine:install:migrations task, but when I'm run this task

rake app:my_engine_engine:install:migrations


I'm getting this error:

rake aborted!
Don't know how to build task 'railties:install:migrations'

Tasks: TOP => app:my_engine_engine:install:migrations
(See full trace by running task with --trace)


Can anyone help me with this trouble?

Answer

Well, I'm find solution to my problem. I just needed to switch to my test app directory and to run there:

rake my_engine_engine:install:migrations

and it works as it should.
