Linking Tickets to Checkin's

It's easy to link a checkin to a ticket... simply include [ticket-uuid] in your commit comment. Now, when you do that, you also have the ability to link a ticket to the associated checkin(s).

This is just one way of doing this, and what I decided to do. You can of course alter it for your own style/layout.

First: Add a "Short UUID" to your View Ticket page. You can do this by:

<th1>
set shortUuid [string range $tkt_uuid 0 9]
</th1>

Then, display that to the user somewhere:

Uuid: $<shortUuid>

All that does is make it easy for the developer to copy/paste a sensible UUID into their commit log.

Now, continuing, on the same View Page add a link to view associated tickets:

<a href="$<baseurl>/timeline?y=ci&s=$<shortUuid>">associated tickets</a>

What this does is searches all checkin's for the tickets uuid, thus, you can now see all checkin's that are linked with the given ticket.
