AttributeError: 'module' object has no attribute 'format_exc'

Nice plugin, but as of today some users are reporting an issue when resolving a ticket (Trac 0.11). I found this ticket which is identical...

​http://trac.edgewall.org/ticket/8031

...and it says that it's a problem with the plugin, so I'm raising it here.

Can anyone test this patch: It seems like to reproduce you need to fail validation on the date.

Hi. I raised this issue - and have now registered.

I'm afraid I don't know how to test the patch. If you can provide some more information on how to apply the patch please let me know.

Thanks.

1. Open datefield/filter.py
2. go to the line that says import traceback
3. change it to "from traceback import traceback"
4. see if it works

Trying again:

2. go to the line that says import traceback
3. change it to "from traceback import traceback"

OK, it looks like my issue can be explained without requiring a patch. The dates were simply in the wrong format.

When I first configured my new custom "Due Date" field it was set to dd/mm/yyyy and the team set about updating their tickets accordingly. Then it transpired that we couldn't sort correctly on this field in the reports, so I reconfigured the dates to be in yyyy/mm/dd format. From that point, anyone updating a ticket got this error. Once all existing dates were changed to yyyy/mm/dd we've had no problems.

Seems obvious now; sorry to waste your time and thanks for the responses.

Resolve as "invalid" or "fixed"?

[Robert Corsaro]

No. It really was a bug. You should have gotten a nicer error message. If you can't test I will.

Oh, right, I'll give it a go then. Watch this space.

I made the change but it behaves in the same way as before, throwing up this error:

Trac detected an internal error:

AttributeError: 'module' object has no attribute 'format_exc'
