[Nitro] Controller not being picked up by dispatcher

Tue Aug 2 04:36:39 EDT 2005

All,

Please can someone help with the follow (extraordinarily) simple
problem: my controller isn't being recognised, what's wrong?

---8<--- run.rb
#!/usr/bin/env ruby
require 'nitro'
require 'src/controller'

STDERR.sync = true if not STDERR.sync

# $DBG = true

include Nitro

Nitro.run do |conf|
  conf.dispatcher = Dispatcher.new(
     '/book' => BookController
  )

  conf.set(
    :name => 'Pendleton House Library',
    :host => '127.0.0.1',
    :port => 9999
  )
end
---8<---

---8<--- controller.rb
require 'nitro/controller'

include Nitro

class BookController < Controller
  # should use the default index method
  def search
    puts "BookController.search"
  end
end
---8<---

---8<--- index.xhtml
<?xml version="1.0"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
                      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
  <body>
  <a href="/book/search">Search</a>
  </body>
</html>

The output I get on the console is:
---8<--- (stdout)
$ ruby run.rb

My guess is that there is something wrong with the dispatcher
configuration but I can't work out what it is. I haven't defined a
dispatcher for '/' as I was expecting that to pick up
/public/index.xhtml and render that. As it is, it looks like attempts
to render '/book/search' are being dispatched to the default
SimpleController and not my BookController.

Any help much appreciated.

Thanks,
Marcus
