[web2py] scheduler: imported unicodedata module in model not visible in a view

[Adi]

unicodedata module is accessible in a view when i test code directly from 
an application, but get the error when run the same code from scheduler. I 
can move the code up to a model (db_scheduler), but just wanted to know if 
imports from models should be visible to Views when run through scheduler? 

Thanks,
Adnan


db_scheduler.py
        import unicodedata

        def send_order_confirmation_email():
            ...
             context=dict(order=order)
             message=response.render(msg_file, context)
          ...send email
            return

Views:
msg_file.html
    {{=XML('<p>%s %s</p>' % \
                                                (row.orderItem.Qty,unicodedata
.normalize('NFKD', \
                                                unicode(row.orderItemDetail.
ProductDesc, 'utf8')).encode('ascii','ignore')))
    }}
