trac-wysiwyg plugin doesn't show

[Etienne Ringuet]

Binary package hint: trac-wysiwyg

When installing trac with trac-wysiwyg the wysiwyg editor is never activated even with

[components]
tracwysiwyg.* = enabled

in trac.ini.

Expected: When editing a wiki page, the wysiwyg option should be shown

Happening: No wysiwyg option is shown.

After installing the plugin you need to do the trac deployment once again
e.g.
trac-admin /srv/trac/YourTracName deploy /usr/share/trac

After this you need to create a symbolic link to jquery.js
ln -s /usr/share/javascript/jquery/jquery.js /usr/share/trac/htdocs/common/js/jquery.js
This link is alread created in /usr/share/pyshared/trac/htdocs/js/
but not copied over to the deployment directory.

After this the trac-wysiwyg plugin worked correct.

I have the same problem with the same version.
Applying the fix did not help either
Any ideas ?

[Etienne Ringuet (eringuet)]

I downloaded the last TRAC release and updated my project. After, I redeployed the project. I didn't need to symlink jquery.

[Mike Dunphy (mdunphy-aptina)]

Here are the errors I get:

So I guess I'll bypass the ubuntu release of trac for 10.04 LTS that I get w/ apt get and try the latest release

[Mike Dunphy (mdunphy-aptina)]

The update fixed it. However I had to completely remove all the ubuntu stuff w/ apt-get remove and use easy_install as it apparently left leftovers around when I just used easy_install. trac-admin still had some pieces and parts of the older version

[Zhang Zhuo (thinkdoggie)]

I had a better solution for this issue.

The reason of this issue is that the handler used in Trac can support "symbolic link", but Apache can. Unfortunately, the file jquery.js which trac-wysiwyg required is a symbolic file stored in /usr/share/pyshared/trac/htdocs/js. If we can serve static resources of <project_url>/chrome/common/* by Apache, the trac-wysiwyg plugin will works.

Add following lines to Apache configuration file:

AliasMatch /projects/[^/]+/chrome/common/(.+) /usr/share/pyshared/trac/htdocs/$1

<Directory /usr/share/pyshared/trac/htdocs>
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>

This fix also works on multiple-project trac site.

[Zhang Zhuo (thinkdoggie)]

In other words, this is not the fault of trac-wysiwyg, but a bug of trac itself. Package trac-wysiwyg merely reveals this bug of package trac. What do you think of?

Can any one deal with this situation?

[Eric van der Vlist (vdv)]

The apache configuration hack was not doing the trick for me and after some investigations, I have noticed that there was no link toward jquery.js in /usr/lib/python2.6/dist-packages/trac/htdocs/js/ ...

Adding a link here:

sudo ln -s /usr/share/pyshared/trac/htdocs/js/jquery.js /usr/lib/python2.6/dist-packages/trac/htdocs/js/

fixed the issue for me.
