python-django file upload 'key error'

Question

I am using python 3.2 & django 1.6. I want to upload to upload a 'csv' file and read data inorder to insert it into database(postgresql). Here is my code
Template

<form id = "ListForm" name = "ListForm" action = "" method = 'POST' enctype="multipart/form-data">
<table>
<tr>
<td>PM List</td>
<td><input type="file" name="file_pm" id="file_pm" ></td>
</tr>   
<tr><td><input type="submit" value="Upload" name="pmUpload" id="pmUpload" class="button"></td></tr>       
</table>
</form>

Python code is:

import cgi
def pmUpload(request):
    form = cgi.FieldStorage()
    fileitem = form["file_pm"]

I got 'KeyError' in the lastline of the above python code.I was trying to read data one by one.

And the full traceback error is

The file should be in request.FILES['file_pm'].
