Hello, I’m new to Rails and expecially to Engines. I’ve just installed the LoginRngine and the UserEngine. I’m developing a new application where I have different type of users with different personal data. The UserEngine like it is now, it doesn’t allow to manage this (right ?) What do you think is the best way to manage this situation ? - expand the engine so that it can handle diffent type of users - forget the engine and manage everything in the application. Simone ---

Just because the provided engine controllers/views don’t provide the mechanisms to edit your custom user data doesn’t mean you can’t use them - you can create your own controllers to edit the data, or use the code-mixing mechanism engines provide to extend/modify the existing controllers to suit your application. It’s important, especially for someone coming recently to Rails, to realise that there does _not_ need to be a 1-1 mapping between models and controllers. - james On 1/30/06, Simone F.

JA\> or use the code-mixing mechanism engines provide to extend/modify the JA\> existing controllers to suit your application. What you mean exactly with “code-mixing mechanism” ? Can you provide some links ? ## Thanks again Simone ---
