I’m new to Ruby, Rails, and this list. I’ve tried searching for an answer but it all seems to be over my head. I have all the books but again they seem to leave me on my own to figure out the stuff that really matters. Where is the best place to find out the details? Exactly what are these much celebrated “naming conventions”; i.e. where do I find an exhaustive list of these rules? Everything runs great under Webrick and then getting it all running under Apache is a nightmare. Why is this? Here’s the kind of output I’m getting in the logs: [Sun Jun 04 19:13:10 2006] [error] mod\_ruby: error in ruby [Sun Jun 04 19:13:10 2006] [error] mod\_ruby: /srv/www/htdocs/bget.org/www/aistracking/app/views/client/list.rhtml:5: uninitialized constant #Module:0x40ab0278::Client (NameError) [Sun Jun 04 19:13:10 2006] [error] mod\_ruby: from (eval):77 [Sun Jun 04 19:13:10 2006] [error] mod\_ruby: from /usr/lib/ruby/1.8/apache/eruby-run.rb:116:in `eval_string_wrap' [Sun Jun 04 19:13:10 2006] [error] mod_ruby: from /usr/lib/ruby/1.8/apache/eruby-run.rb:116:in `run’ [Sun Jun 04 19:13:10 2006] [error] mod\_ruby: from /usr/lib/ruby/1.8/apache/eruby-run.rb:72:in `handler’ [Sun Jun 04 19:13:10 2006] [error] mod\_ruby: from /usr/lib/ruby/1.8/auto-reload.rb:84 I’ve got all kinds of crazy stuff going on in my virtual host record. Individual RBX and RHTML files can be made to work but Rails seems like it always throws some kind of error. Here’s my virtual host record: \ ServerAdmin removed\_email\_address@domain.invalid DocumentRoot /srv/www/htdocs/bget.org/www ServerName [www.bget.org](http://www.bget.org) ServerAlias [bget.org](http://bget.org) \*.bget.org ErrorLog /var/log/apache2/error\_log CustomLog /var/log/apache2/access\_log common DirectoryIndex index.html index.htm index.php index.cfm UseCanonicalName Off HostnameLookups Off ServerSignature On \ Options FollowSymLinks ExecCGI AllowOverride None Order allow,deny Allow from all # If the ruby module is installed, this will be enabled. # for Apache::RubyRun RubyRequire apache/ruby-run # exec files under /ruby as ruby scripts. \ SetHandler ruby-object RubyHandler Apache::RubyRun.instance Options +ExecCGI # exec \*.rbx as ruby scripts. \ SetHandler ruby-object RubyHandler Apache::RubyRun.instance # exec \*.rb as ruby scripts. \ SetHandler ruby-object RubyHandler Apache::RubyRun.instance # # for Apache::ERubyRun RubyRequire apache/eruby-run # # # handle files under /eruby as eRuby files by eruby. \ SetHandler ruby-object RubyHandler Apache::ERubyRun.instance # # # handle \*.rhtml as eruby files. \ SetHandler ruby-object RubyHandler Apache::ERubyRun.instance # # for Apache::ERbRun # RubyRequire apache/erb-run # # # handle files under /erb as eRuby files by ERb. # \ # SetHandler ruby-object # RubyHandler Apache::ERbRun.instance # # # for debug RubyRequire auto-reload My thought is some patient soul will help me.

I have the version distributed in the download for ruby 1.8.4 (2005-12-24) [i686-linux]…I think…er, but truth be known I’m a little fuzzy on where all this stuff came from, I had to download the main ruby package and then something (a package maner of some sort?) called gems and then had to download specific stuff it seems for rails and other specific stuff for eruby…so I forget which package had mod\_ruby in it at this point. I’d be happy to try anything that might work; I’ll look into acquiring a different dispatcher if you think that may be my problem…I’d be happy to use FCGI if I had any idea where to start, but my only testing laboratory is a production server…so it’s a bit sketchy messing around with the innards of Apache…but if I had a clear way forward I might undertake it. Funny thing is that what I see time and again is just, well “You’ll have to fiddle with it.” instead of “This, this, this and this need to be done to make it work.” Perhaps I’ve just been looking in the wrong places. Ok, I know the list isn’t really the place for aimless gripes. I like Ruby. I’m going to try to stick it out. Thanks for your help. Anyone else have any wisdom for me?

If you want to _just get it to run_ -follow the numerous instructions and just run your Rails app on Mongrel below Apache. Seems the simplest way for me. [http://fluxura.com/](http://fluxura.com/) [http://brainspl.at/articles/2006/04/26/dead-simple-deployment](http://brainspl.at/articles/2006/04/26/dead-simple-deployment) sudo gem install mongrel cd /sites/my-rails-app mongrel\_rails start and confiugure the proxying in Apache to forward everything to Mongrel. Will spare you quite some time. You can start many Mongrels and balance between them on the Apache side. You will need the latest-and-greates Apache for it though. Or run it via mod\_fcgi, or via mod\_fcgid (requires Apache 2 as well). Or run lighttpd under apache and Rails as FCGI under lighttpd. – Julian ‘Julik’ Tarkhanov please send all personal mail to me at julik.nl ---

Thanks a lot Julian, I haven’t had a chance to try Mongrel yet, but when I do I’ll be sure to let you and the list know whether I meet with success. I have Apache/2.0.54 which I see is not the latest and greatest (2.2.2)…but I wonder if it’ll do. This sentence “Or run it via mod\_fcgi, or via mod\_fcgid (requires Apache 2 as well). Or run lighttpd under apache and Rails as FCGI under lighttpd.” is basically Greek to me…I just don’t know enough about the details to able to make sense of it. When people say “Open this file, find this line, and edit it to say \_\_\_\_\_,” that works for me, otherwise I’m frequently at a loss. Sorry to be such a newbie.
