Ivan,
When using IronRuby.Rack and debugging the ruby code running, keep a few things
in mind:
1. Enable debug mode for DLR code in your app’s web.config (in the
Microsoft.Scripting section).
2. Because VS breakpoints in blocks don’t work yet, using Debug.Assert
will do the job.
3. IIS has a timeout of 60 seconds per request, which can be annoying
when debugging. In the AppPool configuration that your application is running
in try to max the timeout out so the process you want to debug stays around.
4. Use WinDBG if you want to “man up”, but the VS debugger will be just
fine.
Ivan, your “No route matches "/mocktwitter" with {:method=>:get}” error is
because you need to tell Rails what the root directory on the web-server is so
it can route appropriately. To see how to do this, look at the
IronRuby.Rails.Example
environment.rb<http://github.com/ironruby/ironruby/blob/master/Merlin/Main/Hosts/IronRuby.Rack/IronRuby.Rails.Example/config/environment.rb#L10>:
Rails::Initializer.run do |config|
config.action_controller.relative_url_root = "/IronRuby.Rails.Example" if
ENV['RACK_ENV'] == 'production'
# …
end
Also, I usually set up a separate AppPool, and set it to run as a specific
Windows user, so I can grant read-only permissions to that user for the Ruby
stdlib/gems, and read-write access for the app. Then you don’t have to grant
permissions to IIS_IUSRS for all your stuff.
