AttributeError: 'datetime.datetime' object has no attribute 'encode'

How to Reproduce

While doing a GET operation on /backlog/Product Backlog/global, Trac issued an internal error.

I created a test project to try out the agilo plugin. The product log worked at first until I added a few more requirements, tasks, and stories. After navigating back to the product log, it no longer worked (it just appeared as a blank page with a page title of product log. I received this error when I clicked on the download in .csv format at the bottom of the product log page.

Request parameters:

{'format': u'csv', 'name': u'Product Backlog', 'scope': u'global'}

PluginIssue (AgiloForScrum).

[Martin Häcker <martin.haecker@…>]

@reporter: can you please contact our support google group (details at AgiloForScrum) about this issue? To help us debug this a bit more information would help, most interesting to me: where exactly did you click the CSV-Format link?

Thanks!

@rblank: thanks for the wrangling. :)

[Martin Häcker <martin.haecker@…>]

@reporter: can you please also add details about what data you entered into the test agilo and if you changed any of the standard settings? (as I can't reproduce this issue yet).

Found a bit of a workaround.

Replace the line in csv_export.py

           cols.append(value.encode('utf-8'))

with

            if type(value) is datetime:
                cols.append(value)
            else:
                cols.append(value.encode('utf-8'))

and don't forget imports!

from datetime import datetime
