Can't Install TracJsGanttPlugin on Trac 0.11.1

[anonymous]

I installed successfully TracGanttCalendarPlugin 0.11, then I tried to install TracJSGanttPlugin to test it and compare both plugins. After trying and trying I figured out that I couldn't install the plugin. The .egg is in the right place(plugins directory), and it was generated successfully with no error messages. Trac Log is set to DEBUG and shows no error and not even mentions TracJsGanttPlugin.

I get this when I try to put [[TracJsGanttChart(milestone=Release 1.1)]] in the wiki:

Error: Failed to load processor TracJsGanttChart

No macro or processor named 'TracJsGanttChart' found

If any other information is needed or if something is required to install TracJsGanttPlugin in version 0.11 please tell me.

Thanks

The plugin does not work in 0.11.1. The reason is explained in #9760. If you turn on ​t:TracLogging and restart the service, you'll see the following in the logs:

10:35:20 AM Trac[loader] ERROR: Skipping "tracjsgantt = tracjsgantt": (can't import "cannot import name javascript_quote")

I've previously attached a patch to #9760, and I'll ask the plugin author for permission to commit that change. I have to ask though, why are you using such an old version of Trac?

[Ryan J Ollos]

(In [12096]) Fixes #9760, Refs #10405: Restore compatibility back to Trac 0.11 by adding a fallback for when trac.util.text.javascript_quote is not available (Trac < 0.11.3). Copied from hasienda's patch in [11200].

Beware of #9892 before jumping to the conclusion that the plugin doesn't work. The sample seems to be broken, but ordinary usage of the plugin seems to be okay.

Installed the plugin on trac 0.11.2.1 and it does not load.

get thhis error on trac.log

Skipping "tracjsgantt = tracjsgantt": (can't import "cannot import name to_utimestamp")

[jorge.guerreiro@…]

Resolved with the following changes on tracjsgantt.py

Modified line 6 to from trac.util.datefmt import localtz. Added:

try:
  from trac.util.datefmt import to_utimestamp
except ImportError:
  from trac.util.datefmt import to_timestamp
  to_utimestamp = to_timestamp

Now the plugin gets imported into 0.11.2.1 and shows the sample chart.

Replying to jorge.guerreiro@streambow.com:

Resolved with the following changes on tracjsgantt.py

It is best to leave tickets opened until the issue is fixed in the Trac codebase. While the issue may be resolved for you, tickets should only be marked resolved when the issue is resolved in the public codebase.

In this case, the issue was fixed in [12565] after the issue was reported again in #10808.

Just tried building this plugin again for Trac 0.11.2.1 however it fails to load with a similar to_utimestamp error. However, this time the error occurs in tracpm.py (tested with SVN revision 13472).

Applying this patch fixes the problem and lets the plugin load again with Trac 0.11.2.1:

In 13473:

As in [12565], add a fallback import since to_utimestamp is not available in Trac < 0.12. Fixes #10405.
