I’m just trying RoR and it works very smoothly. I’am also somewhat  
familiar with ruby however I do not know where my Classes are supposed  
to go in RoR.

E.g. my ruby file looks like

include a\_few\_lib\_here

Class function\_name  
def aaaa  
end  
end

#main program  
yadayada = function\_name(parameter)

I understand:

- the main program goes in a controller I have to create
- but where am I suppose to put the Class stuff?

I’ll re-use the Class stuff for different controllers but I’m not sure  
where it is suppposed to go. Thanks.

The “lib” directory is probably what you need; and don’t forget to  
require your lib in environment.
