[Zope] Python Script Trouble

[Laura McCord]

I am having a problem with finding the uploaded fileSize. Currently whe
I use the file.read() function when I view the contents of the file
after it is uploaded it is blank. Perhaps, someone can see what I am
doing wrong. Here is my code:

# I am passing the uploaded file, title, id ....
REQUEST = context.REQUEST
new_context = context.portal_factory.doCreate(context, id)

# Generic editing method (ie. edits id + Metadata)
new_context.plone_utils.contentEdit(new_context, id = id, title = title,
)

spaceAvail = context.Availability()

data = file.read()
fileSize = len(data)

if spaceAvail < 80:
 if fileSize < 30:
  sizeTest = context.getDirectories('/var/www/html/da')
  totalSize = fileSize + sizeTest
  if totalSize > 900:
   message = 'Failure: No available disk space, see system
administrator'
   return ('failure', new_context,{'portal_status_message':message})
  else:
   test = new_context.manage_editPloneExternalFile(title = title,file =
file,REQUEST = REQUEST)
   if not test:
    return ('success',
new_context,{'portal_status_message':context.REQUEST.get('portal_status_
message', 'Content updated.')})
   else:
    return ('failure', new_context,{'portal_status_message':test})
 else:
  errormsg = 'Failure: File exceeds size limitation of 30MB'
  return ('failure', new_context,{'portal_status_message':fileSize})
else:
 errormsg2 = 'Failure: No disk space available in /var directory'
 return ('failure', new_context,{'portal_status_message':errormsg2})

Thanks You.
