I came across the problem, that I needed a sub-ticket plugin for Trac v1.0. I found the SubTicketPlugin for TRAC on trac-hacks.org but also the ChildTicketsPlugin, that comes along with a very neat progress meter for parent tickets, but unfortunately is not yet available for Trac v1.0.
Because I wanted it so much, I searched for a way of having such a progress meter with the SubTicketPlugin. Then finally I found a way of building a site template for Trac, where the progress meter is displayed conditionally. It’s not that easy to understand and also uses some inline python code to cover all conditions, but it should work without further explanation. Just place the site.html in the /templates folder of your trac project.
/templates/site.html
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xi="http://www.w3.org/2001/XInclude"
xmlns:py="http://genshi.edgewall.org/"
py:strip="">
<div py:match="div[@class='description']" py:attrs="select('@*')">
${select('*')}
<?python
subticketCount = 0
if 'ticket' in vars() and ticket.id != None:
from trac.env import open_environment
env = open_environment('D:\Development\TRAC\myapp')
with env.db_query as db:
cursor = db.cursor()
cursor.execute(''.join(["SELECT count(*) FROM subtickets WHERE parent=", str(ticket.id)]))
for row in cursor:
subticketCount=row[0]
?>
<py:if test="subticketCount > 0">
<h3>Progress </h3>
${wiki_to_html(context, ''.join(["[[TicketQuery(format=progress,parents=", str(ticket.id), ')]]']))}
</py:if>
</div>
</html>
I also developed a custom report, showing the tickets and their sub-tickets.
SELECT p.value AS __color__,
id AS ticket,
(SELECT GROUP_CONCAT(summary) FROM ticket WHERE id = parent) AS __group__,
summary,
component, version, milestone,
t.type AS type,
owner, status,
CONCAT(ROUND(100 / (SELECT COUNT(*) FROM subtickets WHERE parent=t.id) * (SELECT COUNT(*) FROM subtickets INNER JOIN ticket ON (child=ticket.id ) WHERE parent=t.id AND status='closed')), "%") AS progress,
CASE WHEN (SELECT COUNT(*) FROM subtickets WHERE parent=t.id) > 0 THEN 'border-bottom:solid 3px #DDD;border-top: solid 3px #DDD;background-color: #DDD' ELSE 'text-indent: 10px' END AS __style__,
time AS created,
changetime AS _changetime,
description AS _description,
reporter AS _reporter
FROM subtickets s
LEFT JOIN ticket AS t ON (parent = t.id)
LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority'
WHERE status <> 'closed'
GROUP BY ticket
UNION
SELECT p.value AS __color__,
id AS ticket,
(SELECT GROUP_CONCAT(summary) FROM ticket WHERE id = parent) AS __group__,
summary,
component, version, milestone,
t.type AS type,
owner, status,
CONCAT(ROUND(100 / (SELECT COUNT(*) FROM subtickets WHERE parent=t.id) * (SELECT COUNT(*) FROM subtickets INNER JOIN ticket ON (child=ticket.id ) WHERE parent=t.id AND status='closed')), "%") AS progress,
CASE WHEN (SELECT COUNT(*) FROM subtickets WHERE parent=t.id) > 0 THEN 'border-bottom:solid 3px #DDD;border-top:solid 3px #DDD;background-color: #DDD' ELSE 'text-indent: 10px' END AS __style__,
time AS created,
changetime AS _changetime,
description AS _description,
reporter AS _reporter
FROM subtickets s
LEFT JOIN ticket AS t ON (child = id)
LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority'
WHERE status <> 'closed'
GROUP BY ticket
ORDER BY __group__ DESC

Howdy, I do believe your web site might be having
browser compatibility problems. Whenever I take a look at your blog in Safari, it looks fine however,
if opening in Internet Explorer, it has some overlapping issues.
I simply wanted to provide you with a quick
heads up! Apart from that, wonderful blog!

I have to thank you for the efforts you’ve put in penning
this blog. I really hope to see the same high-grade blog
posts by you in the future as well. In truth, your creative writing abilities has motivated me to get my very own website now 😉

could you please tell me the steps to do your changes in my machine.
1. I will keep the site.html under /trac/repos/templates/
2. Report where i need to do.
