Plugin doesn't appear in Webadmin + TicketChart macro not found

[glc.nwl@…]

Hi,

After copying TicketCharts.py to my project plugins directory, the plugin is NOT listed in Trac Webadmin plugins section.

• I'm running Trac 0.11.5
• restarted Apache
• when I saw this first problem, I didn't tried to go further in the setup process (didn't installed Open Flash Charts 2 and its version 2 python bindings yet)
• enabled in trac.ini with ticketcharts.* = enabled
• Already have AdvParseArgsPlugin and TicketStats plugins installed and both working fine.
• Couldn't find this kind of issue regarding your plugin on the web.

I guess that it should appear at least in WebAdmin plugin's page, even without OFC, and if I try to call the macro through a wiki page, I get the standard Trac error msg :

Error: Failed to load processor TicketChart

No macro or processor named 'TicketChart' found

So it seems that TicketCharts.py isn't taken at all by Trac

Any thoughts ?

I've recently installed about 10 plugins on Trac and this is the first that doesn't appear on Webadmin. As I'm still a little newbie on Unix, I'd prefer to first ensure that the plug-in is at least "recognized" and executed by Trac, before eventually spending some hours to install and setup Open Flash Charts for nothing (if the plugin still doesn't work after that).

So, if seems possible and logical for you to encounter this issue without having Open Flash Charts installed, just tell me, and I would give a try completing the whole setup process.

Could you help ? This would be nice, as your plugin should be perfect for my needs and I would really like to make it work.

Many thanks in advance ;-)

I confirm that after testing with the whole setup process even installing OpenFlash, nothing happens, your macro .py file isn't recognized nor processed by Trac.

I still have (on Trac 0.11.5) :

Error: Failed to load processor TicketChart

No macro or processor named 'TicketChart' found

With ticketcharts.* = enabled in trac.ini

Ran in to the exact same problem following those exact steps. The Trac log shows the following:

2009-11-27 12:28:31,091 Trac[loader] DEBUG: Loading file plugin TicketCharts from /usr/share/trac/plugins/TicketCharts.py
2009-11-27 12:28:31,101 Trac[loader] ERROR: Failed to load plugin from /usr/share/trac/plugins/TicketCharts.py:

  File "/usr/share/trac/plugins/TicketCharts.py", line 70, in <module>
    import openFlashChart
ImportError: No module named openFlashChart

So, the conclusion is that you've got to install all the pieces, otherwise the plugin wont load.

[Lars Stavholm]

Turns out that the name is wrong.

class TicketChart(WikiMacroBase):

...should be:

class TicketChartMacro(WikiMacroBase):

Now the macro actually loads in my Trac page, no errors in the log, but still no chart.

[Lars Stavholm]

Finally, it works, and it looks absolutely astonishing!

Final tweaks:

http://whatever.host.com/trac

<proj-env>/htdocs

js
OFCDZ.swf

<proj-env>/conf/trac.ini

[ticket-charts]
js_dir = /trac/chrome/site/js
json_dir = /trac/chrome/site/js/json
ofc_file = /trac/chrome/site/OFCDZ.swf

I have the same message, but I don't understand what you mean install all the pieces. Could you describe more details?!

[Lars Stavholm]

What I meant was that you should follow the instructions in the wiki about installing Open Flash Chart, AdvParse plugin, etc. That's the pieces.

Hi,

In my trac instance, everything works except that it keeps "loading" data. Any idea why?

Hi, has anyone gotten this to work on trac 0.11.1?

I'm encountering the same problems as YouLi, with the flash plugin displays the "Loading Data.." forever.

fyi:

• I'm running it under tracd.
• I can see that the js, js/json and open-flash-chart.swf files are loaded.
• I see that the python scripts are compiled and run.

Thanks

Hi, I've got following error saying no module named cjson. Does this requires the prior installation of python-cjson library?

Thanks.

If OpenFlashCharts is not installed, you'll find an error such as the following in your log (see ​t:TracLogging for info on setting the log level to DEBUG):

01:06:46 AM Trac[loader] ERROR: Failed to load plugin from /home/user/Workspace/th6061/tracdev/plugins/TicketCharts.py:

Grab the latest version of OpenFlashCharts:

wget http://downloads.sourceforge.net/project/openflashchart/open-flash-chart/Version%202%20Lug%20Wyrm%20Charmer/open-flash-chart-2-Lug-Wyrm-Charmer.zip

Following the advice in comment:5 I added to trac.ini:

[ticket-charts]
js_dir = /tracdev/chrome/site/js
json_dir = /tracdev/chrome/site/js/json
ofc_file = /tracdev/chrome/site/open-flash-chart.swf

where tracdev is the name of my Trac environment.

openFlashCharts.py depends on the cjson library. On Ubuntu,

sudo aptitude install python-cjson

or edit openFlashCharts.py to replace cjson with json.

Copy python-ofc-library-2 to lib/python2.7/site-packages and edit lib/python2.7/site-packages/easy_install.pth to add the following entry:

./python-ofc-library-2

Install advparseargsplugin.

Edit trac.ini:

[components]
tracadvparseargs.macro.parseargstestmacro = enabled

Make sure that Shockwave flash is installed in your browser.

It should be apparent from comment:13 that the plugin is too difficult to install. Ticket #11072. has been created to handle this.

In my log does not appear this error. Even entered my dir <my trac-env>/plugins and >>did:

import TicketCharts

Without error. I do not understand why these settings:

[ticket-charts]
js_dir = /tracdev/chrome/site/js
json_dir = /tracdev/chrome/site/js/json
ofc_file = /tracdev/chrome/site/open-flash-chart.swf

I need to create these folders or do something related?

Please standby and I'll push some changes shortly that will eliminate the need to deal with those settings on your end :)

A new version has been pushed against #11072. The manual setup steps are eliminated. You only need to install an egg, using one of the methods described on ​t:TracPlugins.

Please report your experience with installing this new version to #11072.
