Tempfile not found when uploading images with the Add function in a Grid

[Paul Ellis]

I am getting this error when users upload an image with the Add function of a grid. As background, it is adding a product which can only be seen by users in a particular group (belong to the same company).

Traceback

1. 2. 3. 4. 5. 6. 7.

Traceback (most recent call last):   File "/home/act/web2py/gluon/main.py", line 505, in wsgibase     request.body.close()   File "/usr/local/lib/python2.7/tempfile.py", line 431, in close     self.unlink(self.name) OSError: [Errno 2] No such file or directory: '/tmp/tmpGdGmPE'

Error snapshot

    <type 'exceptions.OSError'>([Errno 2] No such file or directory: '/tmp/tmpGdGmPE')
 

I have been banging my head against this one for a while and I am not getting anywhere.

I have another function which uses a simple form to add products which can be seen by everyone (admin form) and this has no issues with images.

Can anyone give me a tip or an idea or a direction to continiue searching for a solution?

I am happy to post code but the grid is reasonably complex at 450 lines.

Actually I was looking at the wrong controller function. I have a utility function which returns part of the UI. Somehow when the form is submitted and this is run the tempfile for the image is closed. So by doing this at the end, after the form processing is complete, the problem is solved.
