[Zope] uploading a file via an external method

[Kate Legere]

I've used this to upload files to a specific directory, not to Zope (or as
an Zope object). The problem is that it's looking in the folder for the
files and I'd like it to upload from a chosen directory (or my desktop) in
the same way as manage_addFile does.

external method called upload_external:
 
import os, shutil
 
def upload_external(self,file,REQUEST):
 #check if file was sent correctly
 if file.read(1) == '':
  return '<h2>File does not exist</h2>'
 else:
  file.seek(0)
 iname=os.path.basename(file.filename)
 oname=os.path.join(self.savedir,iname)
 f=open(oname,"wb")
 f.write(file.read())
 # let's get the mime information
 mime_type=file.headers.headers[1]
 user=str(REQUEST.AUTHENTICATED_USER)
 try:
  self.add_entry(path=self.savedir,filename=iname,owner=user)
 except:
  os.remove(oname)
  return '<h2>File upload not completed correctly</h2>'
 return '''<h2>%s was sent correctly, and saved in %s</h2><h3>The Mime Type
of the file is</h3>%s<h3>Saved by</h3>%s''' % (iname,oname,mime_type,user)
 
 
The self.savedir is a property set in the folder which contains the external
method and tells the external method where to put the file.
 
The self.add_entry is an update on a database to keep track of the files
uploaded, etc.
