[Zope] Problems using forms to upload files to Zope

Tue Nov 15 09:25:40 EST 2005

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>

</p>
</td>

</table>
