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

my 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.REQUEST filename = 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: " + filename else: return "File Does NOT Exist: " + filename _________________________________________

What am I doing wrong? Am I using the wrong command?

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.
