[Zope] Problems using forms to upload files to Zope

You should use the getContentType() method - look in the zope book (API - File).

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

  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'

  My code:

  *********HTML FORM**********
  <html>
  <h1 tal:content="template/title">title</h1> 
  <p>Fill out the form below to update the website with the appropriate info:</p>

  <form action="uploadForm.py">
  <table width="100%"  border="0" cellspacing="0" cellpadding="0"> 
    <tr>
      <td width="16%" height="27" align="right"><strong>Your Dept: </strong></td>
      <td width="84%"><input type="text" name="department"></td> 
    </tr>
    <tr>
      <td height="27" align="right"><strong>Document Title:</strong></td>
      <td><input type="text" name="title"></td> 
    </tr>
    <tr>
      <td height="30" align="right"><strong>Filename:</strong></td>
      <td><input type="file" name="upload_filename" ></td> 
    </tr>
    <tr>
      <td height="28" align="right"><strong>Version of File :</strong></td>
      <td><input type="text" name="version"></td> 
    </tr>
    <tr>
      <td height="28" align="right"><strong>URL:</strong></td>
      <td><input type="text" name="url"></td>

    <tr>

      <td rowspan="2"><textarea name="comments" cols="60" rows="5"> 
            </textarea></td>
    </tr>

  def writeDB():

      filename=id

      # 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()
