Rails - Dec 2008 - Question about "partial controllers" sub-applicaktions

Hello,

I''ve got two questions about best practices using Ruby on Rails:

First, think about a website which has several relative independant 
parts: Some news, some dates of fairs, some jobs and so on.
Using the "RoR-filesystem layout" there''s one folder
app/models with all
the models used in these different parts. Another folder app/controllers 
containing the different controllers and so on.
Now think about another website on another server which should consist 
of similar parts but not of all of them.
So if I want to reuse some parts I have to sort out the parts I need. 
That could be tricky. So is there a way to use subfolders in the 
following way:
appnews/controllers
        /models
        /views
appdates/controllers
         /models
         /views
appjobs/controllers
        /models
        /views
and so on?
What''s "the rails way" to do it?

My second question is about "partial controllers": Think of the above 
website. I want to use a (rails-) layout to present all parts in the 
same way. Maybe to columns. The main column should contain the main 
content of the sub-application (e.g. the latest news). And the second 
column should contain content of the other parts (e.g. the latest date 
of fairs). Fetching the stuff out of the database (using the different 
models) would be part of all controllers. So I''d like to use 
"partial-controllers" in a way we use partial views. So I have only to
write the code once and include it from each controller.
So what''s the best way to do it in rails?

Thanks,
Martin

I''ll be watching the answers to this thread myself, as I''m
curious what the
experts will reply.  But I (a newbie) suspect one answer may be to write
plugins for those portions of the code that you anticipate will be reusable.

Of course I haven''t the foggiest idea how one starts off writing code
in a
style suitable for being made into a plugin.  But perhaps you and your
friend Google and start investigating that path while you await answers from
folks who actually do this sort of thing for a living.

http://m.onkey.org/2007/12/9/namespaced-models seems to be talking
about same problems. You might wanna read it.
