<p><a class="reference" href="http://cheetahtemplate.org/">Cheetah</a> is a very good templating language, especially because it's
the one (correct me if i'm wrong) to apply the Object-Oriented model
to Documents. It can seem a bit weird at the beginning but when you get
used to it, you can't live without it :-)</p>
<p>So, i was looking for a good way to overload template parts without
pain, here is how (couldn't find the trick on Cheetah doc):</p>
<ol class="arabic">
<li><p class="first">Assume you have a template <tt class="literal"><span class="pre">Package/Page.tmpl</span></tt> like that:</p>
<pre class="literal-block">
#def footer
This is my foot !
#end def
</pre>
</li>
<li><p class="first">Create a <tt class="literal"><span class="pre">Page_custom.tmpl</span></tt> template:</p>
<pre class="literal-block">
#extends Package.Page
#def footer
$Page.footer($self) Where's my mind ? (dixit the Pixies)
#end def
</pre>
</li>
<li><p class="first">You need to put a <tt class="literal"><span class="pre">self</span></tt> variable in the template's searchList
which is the Cheetah template instance itself :-)</p>
</li>
</ol>
<p>I don't think that trick will work if you don't compile your templates
to Python code.</p>

<p>Good point Deelan ;)</p>
<p>Actually the same trick is used by the framework behind this blog, but with #defS instead of #blockS</p>
<p>See the basic template:</p>
<p><a class="reference" href="http://svn.pythonfr.org/public/alinea/Alinea/templates/SitePage.tmpl">http://svn.pythonfr.org/public/alinea/Alinea/templates/SitePage.tmpl</a></p>
<p>And one custom template (the #extends is added a posteriori):</p>
<p><a class="reference" href="http://svn.pythonfr.org/public/alinea/Alinea/designs/redFlower/SitePage_c.tmpl">http://svn.pythonfr.org/public/alinea/Alinea/designs/redFlower/SitePage_c.tmpl</a></p>

<p>"I don't think that trick will work if you don't compile your templates to Python code."</p>
<p>Correct, actually you have to precompile the base class.</p>
<p>In Subway[1] we managed to automatically compile the whole template hierarchy upon request. Builiding web site using Cheetah and his #extends directive is great. As you have written you can write some default markup into parent template #blockS and then override only when you really need to. No more ugly includes :)</p>
<p>For example, base site.html:</p>
<p><a class="reference" href="http://subway.python-hosting.com/file/sandbox/bikini/view/site.html">http://subway.python-hosting.com/file/sandbox/bikini/view/site.html</a></p>
<p>and one view which overrides both "content" and "nav" #blocks:</p>
<p><a class="reference" href="http://subway.python-hosting.com/file/sandbox/bikini/view/entry/show.html">http://subway.python-hosting.com/file/sandbox/bikini/view/entry/show.html</a></p>
