Hi, I’m just starting with Ruby/Rails, and working through OnLamp’s “Rolling with etc”. I got the cookbook app working OK, but now I want to create a little project of my own. I now realise that the url used to access a controller (say “HelloWorld” doesn’t include the “cookbook” level. So is there only one set of controllers for a given Rails server or what? (I’m using Webrick on XP) Thanks, Jim ---

Which way you go depends on a number of factors. 1. Different ports. You can use -p to tell webrick (or mongrel) to run on a port other than the default 3000. This is the easiest way to go during development. 2. Mapping directories. You can use Apache (or your favorite alternative) to map a /cookbook/ directory to one Rails app and /checkbook/ to another. I think mongrel is a bit touchy doing this, though it may have been fixed in the latest release. This isn’t a good solution during development, since it requires all your apps to run behind Apache and that’s annoying to work with. 3. Mapping subdomains. You can use Apache (etc) to map a subdomain to a Rails app. For example, [cookbook.domain.com](http://cookbook.domain.com) is one app, and [checkbook.domain.com](http://checkbook.domain.com) is another. Again, not a great setup for development but I’ve had good results deploying this way for production. If all you’re doing is playing around with Rails, go with (1) for now. When you’re ready to deploy things, you’ll need to explore options like (2) and (3). – Josh S. [http://blog.hasmanythrough.com](http://blog.hasmanythrough.com) ---

When running the default webrick-backed webserver, you can only run one Rails application, but that is a limitation of the dinky-toy webserver, not Rails itself. - Matt – “I have a cat, so I know that when she digs her very sharp claws into my chest or stomach it’s really a sign of affection, but I don’t see any reason for programming languages to show affection with pain.” – Erik Naggum, comp.lang.lisp ---

Josh: I have a similar situation. I hosted my cookbook and photo album on a web server using apache. I tested both applications using webbrick and different ports and both work fine. I converted them to fcgi and used the root domain linked to index.html in the ~/public\_html directory and pointes to the applications hosted in the root directory ~/cookbook/public and ~/photos/public. The Robins Nest FX | ![cookbook](https://www.ruby-forum.com/cookbook/images/marythumb.jpg "Marys Cookbook Online") | The Robins Family Cookbook | | ![photos]( "Photo Album") | The Robins Family Photo Album | The only problem I have, so far, is that clicking on a link in the photo album list rdirects back to the root url. (http:// [therobinsnestfx.com/?album\_id=74](http://therobinsnestfx.com/?album_id=74)). My ~/public\_html/.htaccess looks like this: Options +FollowSymLinks +ExecCGI RewriteEngine On Redirect [http://therobinsnestfx.com/](http://therobinsnestfx.com/) [http://therobinsnestfx.com/](http://therobinsnestfx.com/) photos/ RewriteRule ^([^.]+[^/])$ http://%{HTTP\_HOST}/$1/ [R=301,L] RewriteCond %{HTTP\_HOST} !therobinsnestfx.com$ RewriteCond %{HTTP\_HOST} !^70.47.57.170 RewriteCond %{HTTP\_HOST} (www.)?([^.]+.)(._)$ RewriteRule ^(._)$ http://%3/$1 [L] I assume the problem is something in the photos .htaccess or routes The .htaccess in photos is: # General Apache options AddHandler fastcgi-script .fcgi AddHandler cgi-script .cgi Options +FollowSymLinks +ExecCGI RewriteEngine On RewriteBase /photos RewriteRule ^$ photos/ [QSA] RewriteRule ^([^.]+)$ $1.html [QSA] RewriteCond %{REQUEST\_FILENAME} !-f #RewriteRule ^(._)$ dispatch.cgi [QSA,L] RewriteRule ^(._)$ dispatch.fcgi [QSA,L] ErrorDocument 500 “ ## Application error Rails application failed to start properly” Any cluse on how to straighten this out?
