RT-Extension-ArticleSubjectOverride - Override Subject when selecting an Article


perl Makefile.PL
make install

May need root permissions

Edit your /opt/rt4/etc/

Add this line:

    Set(@Plugins, qw(RT::Extension::ArticleSubjectOverride));

or add RT::Extension::ArticleSubjectOverride to your existing @Plugins line.

By default, this will only be available on ticket Update with the normal Articles UI. If you'd like to use it on Create, you'll need to enable the config option for Articles on Create.

On RT 4.0.2, you need to apply the included patch to add two necessary callbacks
    $ patch -d /opt/rt4 -p1 < patches/0001-Add-two-new-callbacks.patch
    patching file share/html/Admin/Articles/Classes/Modify.html

This patch is unnecessary for RT 4.0.3 and higher.

Clear your mason cache
    rm -rf /opt/rt4/var/mason_data/obj
Restart your webserver


This extension will add a new dropdown to class basics page. It allows you to choose one of your article custom fields and have it override the subject. When used in a reply, this affects the subject of the transaction, not the ticket. When used on ticket creation, it changes the subject of the ticket. If you do not want this subject custom field to appear in the body of your Article, use the standard class checkboxes to avoid including it.
