Ruby on Rails 3: administration interface generator?

I'm looking for some gem/library able to generate administration interface for my RoR3 project. I don't want to have some library/gem with its own logic and data in some gem repo, I want it to be not just integrated with my app, but be actual part of it, have ability to tweak and modify logic, views, etc...

ATM I've tried rails_admin and it seems to be the best imho, but during development lots of issues came out: i18n issues, additional pag开发者_如何转开发es, custom controls, lack of documentation on extending it, ... There's a lot actually. Maybe for something simple its a perfect match, but not for projects requiring complex administration interface.

So any ideas on gem/library I can use?

Thanks.
