Rails - Feb 2010 - Rails 3 - rails runner doesn't work here

Hi,

I''m currently playing with Rails 3 (I''m new to rails, coming
from PHP
background). Everything works good so far, until yesterday, when I
tried to setup a cronjob.

The most common way to starting regular jobs seems to be using "rails
runner", right? So, as a test I''ve created a class
"Mytest" in /vendor/
mytest.rb:

class Mytest
  def self.hello
     "hello world"
  end
end

Now, when I try to run this method in rails runner like:

shell#  rails runner "puts Mytest.hello"

I get this response:

====== snap
=========/Users/christian/.rvm/gems/ruby-1.8.7-p249/gems/railties-3.0.0.beta/
lib/rails/commands/runner.rb:45: (eval):1: uninitialized constant
Mytest (NameError)
        from /Users/christian/.rvm/gems/ruby-1.8.7-p249/gems/

        from /Users/christian/.rvm/gems/ruby-1.8.7-p249/gems/

        from /Users/christian/.rvm/gems/ruby-1.8.7-p249/gems/
railties-3.0.0.beta/lib/rails/commands.rb:60:in `require''
        from /Users/christian/.rvm/gems/ruby-1.8.7-p249/gems/
railties-3.0.0.beta/lib/rails/commands.rb:60
        from /private/tmp/testapp/script/rails:10:in `require''
        from /private/tmp/testapp/script/rails:10
=====================
I was wondering if I did something wrong. So I checked the same stuff
in Rails 2 on another machine. The same call "./script/runner "puts
Mytest.hello" works there.

I did some other test, but the rails runner script seems to throw this
error on other things too (like, when I created a simple model and try
to do "rails runner "User.new").

The same call in "rails console" does work (in case of "puts
Mytest.hello" prints "hello world").

Is this a bug in Rails 3? I''m using rvm and tried with serveral ruby
versions (ruby 1.8.7.p29, ruby 1.9.1.p378 and ruby 1.9.2-preview1 and
ruby-head). Rails is "3.0.0.beta"

Any ideas? Did I forget something here (beginner mistake), or is this
a (known) bug?

Regards,
Christian

P.S: I''ve found several ways to working with cron/background jobs with
Rails, like rake, background-rb, rails-runner or delayed_jobs. Is
there any recommended way to do this in Rails 3? I''m just wondering
because I feel cronjobs are a common task in web development, and
usually Rails does have a ''recommendation'' for common taks.
:-)

Hm, seems to be a problem in the older rails beta (the one you install
with ''gem install rails --pre'').
With rails -v => Rails 3.0.0.beta1 the error disappears ;-)
