Ruby with apache ActionController::RoutingError (No route matches "/"):

Hi!

I an trying to setup ruby on rails with apache server on ubuntu server
10.04. I have followed toe guid on the ubuntu page.

My main app is located in:

/home/jonas/ruby/apps/rtest1/public

and I created a symlink to /var/www/app using the following command:

sudo ln -s /home/jonas/ruby/apps/rtest1/public /var/www/app

I have also reconfigured the owner of the /home/jonas/ruby/apps/rtest1/
public and /home/jonas/ruby/apps/rtest1/tmp to www:data.

this is my apache.conf file:

<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www
RailsEnv production
RailsBaseURI /app
<Directory /app>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all

    <Directory />
            Options FollowSymLinks
            AllowOverride None
    </Directory>
    <Directory /var/www/>
            Options Indexes FollowSymLinks MultiViews
            AllowOverride None
                Order allow,deny
            allow from all
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
            AllowOverride None
            Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
            Order allow,deny
            Allow from all
    </Directory>

    ErrorLog /var/log/apache2/error.log

    # Possible values include: debug, info, notice, warn, error,

crit,
# alert, emerg.
LogLevel warn

    CustomLog /var/log/apache2/access.log combined

Alias /doc/ "/usr/share/doc/"
<Directory "/usr/share/doc/">
    Options Indexes MultiViews FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
    Allow from 127.0.0.0/255.0.0.0 ::1/128
</Directory>

But when I try to access my program through localhost/app I get error
404 and in the production.log i find:

Started GET “/app” for 192.168.1.3 at Tue Oct 05 18:18:24 +0200 2010

ActionController::RoutingError (No route matches “/”):

All my php software still runs fine under localhost though.

This is probably easy to fix but I have been trying for days and still
can’t get it to work, whats wrong?
