I’m currently developing a project in which I want to have an  
administration section. The development server is running with Bluehost  
([bluehost.com](http://bluehost.com)) on a shared server plan (since I am not always developing  
on one machine, and need to have mobility in development).

I have created a number of controllers as nested controllers. For  
example:

[http://domain.com/acumen/](http://domain.com/acumen/)  
[http://domain.com/acumen/users/](http://domain.com/acumen/users/)  
[http://domain.com/acumen/tasklists/](http://domain.com/acumen/tasklists/)  
[http://domain.com/acumen/projects/](http://domain.com/acumen/projects/)  
[http://domain.com/acumen/tasks/](http://domain.com/acumen/tasks/)  
etc.

The folder structure in the /controllers/ folder mirrors what you see  
there. As far as I can tell, this should work perfectly - I’ve read a  
number of tutorials that do this just as I have done this, and they all  
seem to work. Unfortunately, it is not working.

Whenever I try to access one of the controllers underneath the acumen  
controller, I get the following error:

Routing Error

Recognition failed for “/acumen/tasks/”

My routes.rb file has the following routes in the following order. I  
have also shown a few things that I have tried to resolve the routing  
problems, but they are commented out, as you can see, and should not  
affect right now:

ActionController::Routing::Routes.draw do |map|  
map.connect ‘’, :controller =\> “home”

map.connect ‘:controller/service.wsdl’, :action =\> ‘wsdl’

# Routes to our acumen controller?

#map.connect ‘acumen/:controller/:action/:id’

#map.connect ‘acumen/projects/:action’, :controller =\> ‘projects’

map.connect ‘:controller/:action/:id’  
end

Is this perhaps a problem with the Bluehost hosting environment?

Can you be more explicit - just so I know exactly how your  
/app/controllers folder looks first?

Is it:

/app/controllers/acumen/  
/app/controllers/acumen/users/  
/app/controllers/acumen/tasklists/  
/app/controllers/acumen/projects/  
/app/controllers/acumen/tasks/

or

/app/controllers/  
/app/controllers/users/  
/app/controllers/tasklists/  
/app/controllers/projects/  
/app/controllers/tasks/

Ok well assuming you are wanting to connect to a controller in the  
acumem folder, say ‘TestController’, i.e.

/app/controllers/acumen/test\_controller.rb

Then you need this in the routes.rb

map.connect ‘acumen/:controller/:action/:id’

No this should work is you go to URL:

/acumen/test

It’s the controller names that matter, not the folders. Rails doesn’t  
care which folders you put your controllers in beneath the  
/app/controllers folder (they are all in the same namespace).

I activated that route just below the WSDL route. Currently I’m  
receiving this error:

Unknown action

No action responded to projects

This leads me to think that it is reading it as the acumen controller,  
action projects?

Note: You mentioned namespace. My sub-controllers are declared like  
this:

class Acumen::ProjectsController \< AcumenAreaController

Where I have substituted AcumenArea Controller for  
ApplicationController, so that my layout and login requirements are  
consolidated in a single place. AcumenAreaController looks like this:

class AcumenAreaController \< ApplicationController  
before\_filter :login\_required  
layout “site-layout”  
end

> map.connect ‘acumen/:controller/:action/:id’

All you need is the default route and a controller like

# app/controllers/acument/tasks\_controller.rb

class Acumen::TasksController \< ApplicationController  
…  
end

Just an idea… try it with all the controllers subclassing the  
ApplicationController instead and see if that works, i.e.

class Acumen::ProjectsController \< ApplicationController

If so, then using the module name ‘Acumen’ is causing the problem. Just  
use a different name from ‘Acumen’ in case it conflicts with the path  
/acumen/
