Hi,

## I’m building an app which will become quite big (I hope 😉 ) and so I want to separate admin part and customers part. By separate, I mean not 2 namespaces (=1 app), but really 2 app (so I can shutdown customers and keep admin access for example). But, because the logic/model is the same, and some conf too, I would like to keep it in one directory (a rails 3 app folder). In rails 3, the app is a rack app, we have :

## module XXXX class Application \< Rails::Application …

## So I was thinking of doing 2 app like this inside my application.rb

module XXXCustomers  
class Application \< Rails::Application  
…

## module XXXAdmin class Application \< Rails::Application …

I could define the path for controllers and views  
{controllers,views}/admin — {controllers,views}/customers

My questions/problems are

- when I start the server how to tell it to start the admin app or the  
customers app. Maybe a rake parameter ?
- is there other people who had try to do this
- would you recommend me to use a different manner. For ex : share only  
the model between 2 “real” app
- any other suggestions

Thanks
