Trac Custom fields are not displaying the Wiki formatting

[michael.hayes@…]

I've created several custom fields in the [ticket-custom] section of our configuration file. E.g.

evaluation.cols = 80
evaluation.format = wiki
evaluation.label = Evaluation
evaluation.order = 320
evaluation.rows = 20
evaluation = textarea

This should specify that when the field is populated with wiki formatting it changes the format to bold etc. However this does not occur. The field is displaying '''test'''.

Whats stranger is when I do the same in the description field, i get the correct formatting, or if i load up tracwysiwyg, it accepts the formatting is correct.

We are currently using Trac 1.0.9 and traccustomfieldplugin 0.2.8. Can someone help direct us to how to force the wiki formatting to be accepted.

It works for me with Trac 1.0.9. This is most likely an InstallationIssue. Please try with ​TracWysiwygPlugin disabled.

This plugin is currently disabled. We have version 0.12.0.5 installed, but not active.

However this has still not fixed the problem.

Hi,

Have you been able to progress this? I'm going to install a fresh version to test it out tomorrow, and would appreciate some input before going through the process.

I cannot reproduce and I don't see what the issue could be with the software. I suspect it is an InstallationIssue.

I guess that !'''test!''' is stored in the field. Please check the record in ticket_custom table like this:

-- replace 42 with your ticket's id
SELECT * FROM ticket_custom WHERE ticket=42 AND name='evaluation';

[michael.hayes@…]

I've attached a file with the output. It looks as though its just outputting

'''test'''

Please post screenshot of the ticket view and trac.ini.

It works for me with Trac 1.0.10.

Hi,

I've been trying some debugging myself. We have been using Trac 1.0.1 successfully with this config file, and it has had no issues. I've been testing a little with tracd this morning, and have got some interesting results.

On Trac 1.0.9, it does not work, and on Trac 1.0.10, the wiki text does not work. See attached image.

However, the same config file is working successfully on 1.0.1 when i install it (see attached image).

Thanks for the investigating!

Would you please try to disable all components? I guess hiddenfields and/or templatedfields plugins lead the issue….

[michael.hayes@…]

I've tried removing all the plugins, and changing the config file, and running basic trac, but still no change. I've attached a picture showing the new state.

If customized templates are put into $ENV/templates directory, please try to remove the templates. We've changed ticket_box.html after Trac 1.0.1.

See log:/branches/1.0-stable/trac/ticket/templates/ticket_box.html and [13389].

Replying to Jun Omae:

Good thought.

With that in mind, maybe this is a case of not having executed the deploy command after upgrade: TracUpgrade#a5.Refreshstaticresources. Probably unrelated to deploy command since it only affects static resources, not templates.

[michael.hayes@…]

This has solved the problem.

I've looked at our template, and modified it to include:

<py:if test="field">
  <py:choose test="">
    <py:when test="'rendered' in field">${field.rendered}</py:when>
      <py:otherwise>
      ${wiki_to_html(context, ticket[field.name], escape_newlines=preserve_newlines)}
    </py:otherwise>
  </py:choose>
</py:if>

However, I would ideally like to do a test for field.format = wiki. Do you know what the code should be to achieve this? I cannot seem to get this or anything similar to generate data.

[Ryan J Ollos]

If you had to modify the templates to add that section, then your Trac installation is not utilizing the Trac templates from Trac 1.0.9. You have an InstallationIssue, and should remove and reinstall Trac. If you let us know your platform, python version and how you installed Trac, we can give some hints on how to uninstall Trac.

You could also try installing to a virtual environment if you have python-virtualenv package installed. If you are running Python 2.7.9 or later, or install python-pip:

$ virtualenv pve
$ . pve/bin/activate
$ pip install trac

Installing into a virtualenv will give you a clean site-packages directory that will be unaffected by previous Trac installations, as long as you are using ​virtualenv 1.7 or later and don't specify the --system-site-packages flag.

I may have misunderstood. If you have a custom ticket_box.html, the best solution would be to implement your customizations in a plugin that implements IRequestFilter. The second best solution would be to diff your ticket_box.html against the version of the template that you copied, and apply the changes to the latest ticket_box.html from 1.0.9 (or even better, install the latest, Trac 1.0.11).

The test for format = wiki can be seen in ticket_box.html: tags/trac-1.0.9/trac/ticket/templates/ticket_box.html@:96#L86​.
