I'd suggest manage_upload instead...

File objects have a method called 'update_data' 
which may be of use. Look in the ZopeBook for details.

  Subject: [Zope] How to Update files that 
  are already uploaded
  Hi all,I'm trying to update a file thats already been 
  uploaded. I can't figure out what command to use, 
  "update_data"/"manage_upload"/"manage_edit". I've settled (so far) on 
  manage_upload but it doesn't work. I get the error: Error Type: 
  AttributeError Error Value:manage_uploadmy 
  code:_# Takes the filename 
  from a form searches my ZSQL method for the existence of the file, and then 
  should update the file. REQUEST=context.REQUESTfilename = 
  REQUEST.form.get('file')filename=filename.split('\\')[-1]result=container.Show_filename_selected(filename=filename)if 
  result: fname= container.Show_filename_selected 
  (filename=filename).tuples()[0][3] 
  context.manage_upload([filename,REQUEST]) return "File 
  Exists... UPDATE: " + filenameelse: return "File 
  Does NOT Exist: " + filename_ 
  What am I doing wrong? Am I using the wrong command?Thanks in 
  advance,mjakowlew

Well, first of all where comes the ZSQL Method into 
the game? ZODB is already a database and knows best
which objects exist and which do not.

Also you need to acquire the actual object if its there:

if has_attr(container.Filerepository,fileid):
fileobj=getattr(container.Filerepository,fileid)
fileobj.manage_upload( ...)
return File %s exists. Updated it. % fileid
else:
container.Filerepository.manage_addFile(...)


sketchy but you should get the picture.
