I am executing some scripts from the script directory.

## script files:

script1:  
require File.dirname( **FILE** ) + ‘/…/config/boot’  
require File.dirname( **FILE** ) + ‘/…/config/environment’  
module DataLoad

## end

## script 2 being executed:

require File.dirname( **FILE** ) + ‘/…/config/boot’  
require File.dirname( **FILE** ) + ‘/…/config/environment’

## classB.generate

classes in model dir:

class A  
include DataLoad  
end

class B \< class A  
def self.generate  
end

Error executing the script2:

`const\_missing’: uninitialized constant AvailabilityReport::DataLoad  
(NameError)

You’ll need to require the file defining that module yourself
