[Zope] Re: Problems using forms to upload files to Zope

I don't know why getContentType() doesn't exist anymore?!  a quick 'dir' of a file instance attributes yields:

['close', 'filename', 'fileno', 'flush', 'headers', 'isatty', 'read', 'readinto', 'readline', 'readlines', 'seek', 'tell', 'truncate', 'write', 'writelines', 'xreadlines']

Anybody out there know what happened to 'getContentType'?

However, there is always a work around:  REQUEST['fname'].headers['Content-Type']
should get you what you want.

  Okay I corrected:

  <form action="uploadForm.py" method="post" enctype="multipart/form-data">

  and also tried the getContentType, but I get the error:

  Error Type: AttributeError
  Error Value: FileUpload instance has no attribute 'getContentType'

  ****uploadForm.py****
  def content_type(self):
      return self.getContentType()

  def writeDB():
      # get sql method
      insert=container['insert_fileapps']

      REQUEST=context.REQUEST

      department = REQUEST.form.get('department')
      title = REQUEST.form.get ('title')
      filename = REQUEST.form.get('upload_filename')

      upload_contents= content_type(filename)

      if content_type.find('image')!=-1:
          context.manage_addImage(id, file, title)
      else: 
          context.manage_addFile(id, file, title)
      return 'Finished'

      version = REQUEST.form.get('version')
      url = REQUEST.form.get('url')
      ownerapp = REQUEST.form.get('ownerapp')
      isoapp = REQUEST.form.get('isoapp')
      comments = REQUEST.form.get('comments')
      date = REQUEST.form.get('date')

      filename=id
      filename = filename.split('\\')[-1]

      # call it, passing arguments
      insert( department=department, title=title, filename=filename, version=version, url=url, ownerapp=ownerapp, isoapp=isoapp, comments=comments, date=date)

      # return a confirmation page
      page=container['thanks.html ']
      return page()

  writeDB()

    Here's what I'm trying to accomplish:

    1. The user fills out a form page with various fields 
    2. The user selects a file to upload
    3. when the user hits submit two things should happen:
          - The file selected is uploaded 
          - all the filled out form fields are written to the database (MS SQL)

    This is my current problem:
    The writting to the database part works fine on it's own, but when combined with the file upload I get this error 

    Error Type: AttributeError
    Error Value: 'NoneType' object has no attribute 'headers'
