How to add trackback to your rendered output

PyCS is now able to do trackback. I am currently playing around with Python Desktop Server to get it to render trackback links. A description of how to do it follows.

ATTENTION: This is only needed for version 0.4.20. With version 0.4.21, trackback client support for use with Python Community Server is automatic, so you don't need to patch your themes! I leave this story up, so you can see how to do patches and changes, if you need to.

There are two nuggets you need to create:

• trackbackScript: Script to fetch trackback counters
• trackbackLink: Link to the trackback page

You need to call them like the commentsScript and weblogCommentsLink macros in your WeblogRendering.tmpl. Change your WeblogRendering.tmpl as follows:

$macros.commentsScript()
$nuggets.trackbackScript()
<table border=0 width="100%">
#set lastdate = ''
#if $year and $month and $day
#set list = $current.getRecentPosts(year=$year, month=$month, day=$day, onhome=$onhome, category=$category)
#elif $year and $month
#set list = $current.getRecentPosts(year=$year, month=$month, onhome=$onhome, category=$category)
#else
#set list = $current.getRecentPosts(onhome=$onhome, category=$category)
#end if
#for $post in $list
#if $post.pubdate != $lastdate
#if $lastdate
</table>
</td></tr>
<tr><td>&nbsp;</td></tr>
#end if
<tr><td class="whitebox" colspan=2>
<table width="100%">
<tr><td><a href="$current.getCloudUrlForDay($post.pubtime,category=$category)">$post.pubdate</a></td></tr>
#set $lastdate = $post.pubdate
#else
<tr><td>&nbsp;</td></tr>
#end if
#if $post.title
<tr>
#if $post.link
<td><h3><a name="$post.id"></a><a href="$post.link">$post.title</a></h3></td>
#else
<td><h3><a name="$post.id"></a>$post.title</h3></td>
#end if
</tr>
#end if
<tr>
<td>
#if not($post.title)
<a name="$post.id"></a>
#end if
#if $post.rendered
$post.rendered</td>
#else
$post.text</td>
#end if
</tr>
#if $post.source
<tr><td colspan=2 align="right" class="smallfont">$_('Source:')
#if $post.sourceurl
<a target="_new" href="$post.sourceurl">$post.source</a>
#else
$post.source
#end if
</td></tr>
#end if
<tr><td align="left">
<span class="smallfont">
$_('posted at') $macros.Time($post.pubtime)
&nbsp;&nbsp;
$macros.weblogPermaLink($post.id, $post.pubtime, $category)
&nbsp;&nbsp;
$macros.weblogCommentsLink($post.id, $post.pubtime, $category)
&nbsp;&nbsp;
$nuggets.trackbackLink(id=$post.id)
</span>
</td></tr>
#end for
#if $lastdate
</table>
</td></tr>
#end if
</table>

If you want to have trackback links in your RSS feed, you can change your RSSFeedRendering.tmpl as follows:

<?xml version="1.0" encoding="iso-8859-1"?>
<rss version="2.0">
<channel>
<title>$current.getRSSTitle(category=$category)</title>
<link>$current.getStaticUrl(category=$category)</link>
<description>$current.getRSSDescription(category=$category)</description>
<language>$_PyDS.language</language>
<copyright>$_('Copyright') $request.year $prefs.getXML('private', 'name')</copyright>
<lastBuildDate>$current.getRSSNewestDate(category=$category)</lastBuildDate>
<generator>$tools.version</generator>
<managingEditor>$prefs.getXML('private','email')</managingEditor>
<webMaster>$prefs.getXML('private','email')</webMaster>
<category domain="http://www.weblogs.com/rssUpdates/changes.xml">rssUpdates</category>
#set $skipHours = $current.getRSSSkipHours(category=$category)
#if $skipHours
<skipHours>
#for $hour in $skipHours
<hour>$hour</hour>
#end for
</skipHours>
#end if
#for $item in $current.getRSSItems(category=$category)
<item>
#if $item.title
<title>$item.title</title>
#end if
#if $item.link
<link>$item.link</link>
#end if
<description>$item.description</description>
<guid>$item.guid</guid>
#if $item.comments
<comments>$macros.quoteXML($item.comments)</comments>
#end if
#if $current.name in ('weblog',)
#set $tburl = $macros.unquoteXML($item.comments.replace('comments.py','trackback.py'))
#set $tburl = $tburl[:$tburl.rfind('&link=')]
<trackback:ping rdf:resource="$macros.quoteXML($tburl)"/>
#end if
<pubDate>$item.pubdate</pubDate>
#if $item.source and $item.sourceurl
<source url="$item.sourceurl">$item.source</source>
#end if
</item>
#end for
</channel>
</rss>
