Hi All,

I’m trying to build a web application that will have an interface for  
developers to write ‘modules’ to add to the application. I’m currently  
following this structure:

app/controllers \<= The main application controllers.  
modules/controllers/ \<= Controllers for each extra module.

In config/environment.rb I’ve added the following:

config.controller\_paths \<\< “modules/controllers”

The application works fine when accessing controllers in the main  
application structure but gives an ‘Undefined Constant’ error when I  
try and access a controller in the modules directory using a URL like:  
‘[http://localhost:3000/ModuleName/Controller/Action](http://localhost:3000/ModuleName/Controller/Action)’. I am using the  
default routing.

Am I missing something really obvious? Or is there a better way of  
achieving the same thing?

Thanks,  
Rhys

Do you also need to add those paths to the load path ?

Ahhh, that worked. Thanks very much for that.
