Roundup Wiki

This is a combination of a reactor that creates a static template file including all the users and an example how to make use of the created template. The solution was initially developed by Marcus Priesch -- I'm just documenting it, since the mailinglist archives are unavailable from time to time::

• Note that the example above assumes a "status" attribute of the user class that is not present in the standard tracker. Furthermore we originally hat special alias-users that were permitted on the nosy-list but not permitted as the responsible person for an issue. So if anybody simplifies this code to work with the roundup standard tracker, it would be nice if the result is shared on this page. How to use it in html templates, the macro has four parameters: - name: the name of the cgi variable - form: the name of the form - dont_care: whats displayed as "dont care which user" - selected: the id which gets automatically selected

The following example is a roundup link-attribute, the "supervisor" field of the user class (the utils.fieldname utility function creates the localised field name with a link to a documentation popup in our implementation)::

• <tr>

  • <th tal:content="structure python:utils.fieldname('user', 'supervisor')"/> <td>

    • <tal:block tal:define="name string:supervisor;

      • form string:user_form; dont_care string:don't care;

        selected context/supervisor/id | string:0">

      • <tal:block metal:use-macro="templates/userlist/macros/user"></tal:block>

      </tal:block>

    </td>

  </tr>

The following example is for a multilink-property called 'authors'::

• <tr>

  • <th class="required"

    • tal:content="structure python:utils.fieldname (classname, 'authors')" />

    <td colspan="3">

    • <tal:block tal:define="size string:3;

      • name string:authors; form string:itemSynopsis; dont_care string:don't care;

        selected python:str([u.id for u in context.authors.reverse ()] or [])[1:-1]">

      • <tal:block metal:use-macro="templates/userlist/macros/user_multi"></tal:block>

      </tal:block>

    </td>

  </tr>
