Windows 2000 SP4  
Ruby 1.8.6  
Rail 1.2.6

I’m trying to create a Rail application for our internal use to  
provide a one stop access to services. I’m currently trying to get the  
Server.status, Service.stop and Service.start to work through a model  
in Rails. The Service.\* functions work well through Ruby itself, but  
seems to have problem through a Rails Model. I’ve been trying to  
display the status of the MySQL service.

\*\*\* Model

require “win32/service”

class Servicectl

include Win32

attr\_reader :state

```
def servicestatus(service_name, host_name)
  @state = Service.status(service_name, host_name)
end

def servicestart(service_name, host_name)
  Service.start(service_name, host_name)
end

def servicestop(service_name, host_name)
  Service.stop(service_name, host_name)
end

```

end

\*\*\* Controller

class ServicectlController \< ApplicationController

def show  
service\_state = Servicectl.new  
service\_state.servicestatus(“MySQL”,nil)  
@status = service\_state.state  
end

end

\*\*\* Show View

\<%= @status %\>

The following error is posted to the development.log.

I have no idea why it is failing, I’m hoping someone might have a clue  
for me.

For reference this is the working code which works well though Ruby  
itself.

\*\*\* service.rb

require “win32/service”

class ServiceController

include Win32

attr\_accessor :state

```
def status(service_name, host_name)
  @state = Service.status(service_name, host_name)
end

def start(service_name, host_name)
  Service.start(service_name, host_name)
end

def stop(service_name, host_name)
  Service.stop(service_name, host_name)
end

```

end

\*\*\* Output:

C:\Shared\SourceCode\Ruby\>ruby service.rb  
running

Thanks for all your time,
