Hi people,

I’m using nested controllers in my dev env without any problems.

Well… I’ve got a controller which is a nested controller of  
Customerbackend:

class Customerbackend::AdvertisementController \< ApplicationController  
layout “Customerbackend”

so… my AdvertisementController used the layout of Customerbackend… so  
far no problem. The AdvertisementController works like a charm in dev  
mode.

I’m opening the controller with a link\_to method like this:

\<%= link\_to ‘Anzeigenverwaltung’, :controller =\>  
‘/customerbackend/advertisement’, :action =\> ‘listAdvertisements’%\>

On my production server I’m getting the following error when I try to  
access it :

Processing AdvertisementController#listAdvertisements (for 89.61.205.195  
at 2007-11-12 12:39:55) [GET]  
Session ID: b9ef65c1265a02809b583c0133183407  
Parameters: {“format”=\>“jpg”, “action”=\>“listAdvertisements”,  
“id”=\>“404”, “controller”=\>"/customerbackend/advertisement"}

ActionController::MissingTemplate (Missing layout  
/var/www/saarbabes2/releases/20071112112035/app/views/layouts/Customerbackend.rhtml):

The curious thing is that rails tries to call Customerbackend.rhtml  
instread customerbackend.rhtml which does exist !!

Does anyone have a solution to my problem ?? What am I doing wrong ??

Regards,  
Alex

because you told it that the layout was Customerbackend not  
customerbackend ? I’m guessing that in development you’re using a mac  
or windows so filenames are case-insenstive, but when you deploy on a  
linux box then suddenly case matters.

Thank you man !!! I thought MAC uses case-sensitive files too… my  
mistake

Hi again,

well changing the filename from my previous post works like a charm…  
but now I’ve got another problem… 'cause my nested controller doesn’t  
get called. I’m getting a 404 error… my production.log tells me the  
following:

Processing CustomerbackendController#advertisement (for 89.61.205.195 at  
2007-11-12 16:41:05) [GET]  
Session ID: 5a04b66b8ec84b845587f7384ff62247  
Parameters: {“action”=\>“advertisement”, “id”=\>“listAdvertisements”,  
“controller”=\>“customerbackend”}

ActionController::UnknownAction (No action responded to advertisement):

I’m using the following link\_to to access my controller:

\<%= link\_to ‘Anzeigenverwaltung’, :controller =\>  
‘/customerbackend/advertisement’, :action =\> ‘listAdvertisements’%\>

damn… why does it work in my development environment but not in the  
production env ??

Alex

Hi,

my folder layout looks like this:

-controllers  
–admin\_controller.rb  
–customerbackend\_controller.rb  
–admin  
—advertisement\_controller.rb  
–customerbackend  
—avertisement\_controller.rb

And here’ the names of my controllers:

CustomerbackendController \< ApplicationController  
Customerbackend::AdvertisementController \< ApplicationController  
AdminController \< ApplicationController  
Admin::AdvertisementController \< ApplicationController

So… do you see my error ??

Regards,  
Alex

Are the .rb files containing the controllers or the various folders  
all named with the correct case?

I’m not sure why this works in development: how is it suppose to  
disambiguate  
customerbackend/advertisement (calling the advertisement action of the  
customerbackend controller)  
customerbackend/advertisement (calling the index action of  
CustomerBackend::Advertisement

you should pick your names so that they don’t clash like this.

Hi,

I found the solution… just adding the following route:

map.connect ‘:controller/:action/’
