ruby on rails - How to move ActiveAdmin.register_page to a gem? -

I want to move some code from the app / admin folder to an external gem.

I have tried it many times and not successfully - page does not appear in ActiveAdmin.

Can anyone tell me in some direction?

I would say that you should look at the gem file structure for some time

 < Code> your_gem └── lib ├── admin │ └── some_model.rb └── your_gem.rb  

and file your_gem.rb in Should be required 'admin / Some_model'
