• the error doesn't happen with just [[TracJSGanttChart(sample=1)]]
• the error also happens with simple milestone names without spaces

Have the same issue.

centos 5.6 apache mod_python trac 11.7

Using the sample setting doesn't throw an error but I don't see a gantt chart.

I reckon it's because I'm driving a 0.12.2 with Babel for internationalization on board. And probably the Gantt developers have just a non-Unicode version installed. And somewhere they don't use something like a unicode-to-simple_char_string converter.

I had the same issue (centos 5.6 / trac 11.5)

I got it "fixed" by replacing the line

# This is the format of start and finish in the Trac database
self.dbDateFormat = self.config.get('trac-jsgantt', 'date_format') 

with

self.dbDateFormat = '%Y-%m-%d'

(which is what I had in the config file as well, so I took a guess this might work :) )

And then I got nice charts.

Since the last traceback call of the ganttplugin was the equivalent of the OP's:

File "build\bdist.win32\egg\tracjsgantt\tracjsgantt.py", line 594, in _add_milestones
format_date(ts, self.dbDateFormat) 

, it seems the self.config.get function can return unicode strings and trac's format_date function can only handle non-unicode strings.

Well, maybe this helps...

Thanks for your hint that gives my internet-searching the right keywords... and after reading ticket/7698 and [9596] it seems to me that this might be the bugfix at browser/tracjsganttplugin/0.11/tracjsgantt/tracjsgantt.py:

- self.dbDateFormat = self.config.get('trac-jsgantt', 'date_format')
+ self.dbDateFormat = str(self.config.get('trac-jsgantt', 'date_format'))

Anyway, now the chart appears for me again.

(In [10687]) Make sure dbDateFormat is not unicode. Refs #9124.

It appears that in Trac 0.12, configuration options are returned as unicode strings but the Python date conversion routines insist on a simple string.

Converting the value to a string explicitly seems to do no harm in 0.11 and hopefully will just work in 0.12 (I can't test there).

You can close this ticket. Works now. Thanks.
