<p class="last">Most of the inheritance examples here take advantage of a feature that&#8217;s
new in Mako as of version 0.4.1 called the &#8220;block&#8221;.  This tag is very similar to
the &#8220;def&#8221; tag but is more streamlined for usage with inheritance.  Note that
all of the examples here which use blocks can also use defs instead.  Contrasting
usages will be illustrated.</p>
</div>
<p>Using template inheritance, two or more templates can organize
themselves into an <strong>inheritance chain</strong>, where content and
functions from all involved templates can be intermixed. The
general paradigm of template inheritance is this: if a template
<tt class="docutils literal"><span class="pre">A</span></tt> inherits from template <tt class="docutils literal"><span class="pre">B</span></tt>, then template <tt class="docutils literal"><span class="pre">A</span></tt> agrees
to send the executional control to template <tt class="docutils literal"><span class="pre">B</span></tt> at runtime
(<tt class="docutils literal"><span class="pre">A</span></tt> is called the <strong>inheriting</strong> template). Template <tt class="docutils literal"><span class="pre">B</span></tt>,
the <strong>inherited</strong> template, then makes decisions as to what
resources from <tt class="docutils literal"><span class="pre">A</span></tt> shall be executed.</p>
<p>In practice, it looks like this. Here&#8217;s a hypothetical inheriting
template, <tt class="docutils literal"><span class="pre">index.html</span></tt>:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## index.html</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">inherit</span> <span class="na">file=</span><span class="s">&quot;base.html&quot;</span><span class="cp">/&gt;</span><span class="x"></span>

<span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;header&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">    this is some header content</span>
<span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>

<span class="x">this is the body content.</span>
</pre></div>
</div>
<p>And <tt class="docutils literal"><span class="pre">base.html</span></tt>, the inherited template:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## base.html</span><span class="x"></span>
<span class="x">&lt;html&gt;</span>
<span class="x">    &lt;body&gt;</span>
<span class="x">        &lt;div class=&quot;header&quot;&gt;</span>
<span class="x">            </span><span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;header&quot;</span><span class="cp">/&gt;</span><span class="x"></span>
<span class="x">        &lt;/div&gt;</span>

<span class="x">        </span><span class="cp">${</span><span class="bp">self</span><span class="o">.</span><span class="n">body</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>

<span class="x">        &lt;div class=&quot;footer&quot;&gt;</span>
<span class="x">            </span><span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;footer&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">                this is the footer</span>
<span class="x">            </span><span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">        &lt;/div&gt;</span>
<span class="x">    &lt;/body&gt;</span>
<span class="x">&lt;/html&gt;</span>
</pre></div>
</div>
<p>Here is a breakdown of the execution:</p>
<ol class="arabic">
<li><p class="first">When <tt class="docutils literal"><span class="pre">index.html</span></tt> is rendered, control immediately passes to
<tt class="docutils literal"><span class="pre">base.html</span></tt>.</p>
</li>
<li><p class="first"><tt class="docutils literal"><span class="pre">base.html</span></tt> then renders the top part of an HTML document,
then invokes the <tt class="docutils literal"><span class="pre">&lt;%block</span> <span class="pre">name=&quot;header&quot;&gt;</span></tt> block.  It invokes the
underlying <tt class="docutils literal"><span class="pre">header()</span></tt> function off of a built-in namespace
called <tt class="docutils literal"><span class="pre">self</span></tt> (this namespace was first introduced in the
<a class="reference internal" href="namespaces.html"><em>Namespaces chapter</em></a> in <a class="reference internal" href="namespaces.html#namespace-self"><em>self</em></a>). Since
<tt class="docutils literal"><span class="pre">index.html</span></tt> is the topmost template and also defines a block
called <tt class="docutils literal"><span class="pre">header</span></tt>, it&#8217;s this <tt class="docutils literal"><span class="pre">header</span></tt> block that ultimately gets
executed &#8211; instead of the one that&#8217;s present in <tt class="docutils literal"><span class="pre">base.html</span></tt>.</p>
</li>
<li><p class="first">Control comes back to <tt class="docutils literal"><span class="pre">base.html</span></tt>. Some more HTML is
rendered.</p>
</li>
<li><p class="first"><tt class="docutils literal"><span class="pre">base.html</span></tt> executes <tt class="docutils literal"><span class="pre">self.body()</span></tt>. The <tt class="docutils literal"><span class="pre">body()</span></tt>
function on all template-based namespaces refers to the main
body of the template, therefore the main body of
<tt class="docutils literal"><span class="pre">index.html</span></tt> is rendered.</p>
</li>
<li><p class="first">When <tt class="docutils literal"><span class="pre">&lt;%block</span> <span class="pre">name=&quot;header&quot;&gt;</span></tt> is encountered in <tt class="docutils literal"><span class="pre">index.html</span></tt>
during the <tt class="docutils literal"><span class="pre">self.body()</span></tt> call, a conditional is checked &#8211; does the
current inherited template, i.e. <tt class="docutils literal"><span class="pre">base.html</span></tt>, also define this block? If yes,
the <tt class="docutils literal"><span class="pre">&lt;%block&gt;</span></tt> is <strong>not</strong> executed here &#8211; the inheritance
mechanism knows that the parent template is responsible for rendering
this block (and in fact it already has).  In other words a block
only renders in its <em>basemost scope</em>.</p>
</li>
<li><p class="first">Control comes back to <tt class="docutils literal"><span class="pre">base.html</span></tt>. More HTML is rendered,
then the <tt class="docutils literal"><span class="pre">&lt;%block</span> <span class="pre">name=&quot;footer&quot;&gt;</span></tt> expression is invoked.</p>
</li>
<li><p class="first">The <tt class="docutils literal"><span class="pre">footer</span></tt> block is only defined in <tt class="docutils literal"><span class="pre">base.html</span></tt>, so being
the topmost definition of <tt class="docutils literal"><span class="pre">footer</span></tt>, it&#8217;s the one that
executes. If <tt class="docutils literal"><span class="pre">index.html</span></tt> also specified <tt class="docutils literal"><span class="pre">footer</span></tt>, then
its version would <strong>override</strong> that of the base.</p>
</li>
<li><p class="first"><tt class="docutils literal"><span class="pre">base.html</span></tt> finishes up rendering its HTML and the template
is complete, producing:</p>
<div class="highlight-html"><div class="highlight"><pre><span class="nt">&lt;html&gt;</span>
    <span class="nt">&lt;body&gt;</span>
        <span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;header&quot;</span><span class="nt">&gt;</span>
            this is some header content
        <span class="nt">&lt;/div&gt;</span>

        this is the body content.

        <span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;footer&quot;</span><span class="nt">&gt;</span>
            this is the footer
        <span class="nt">&lt;/div&gt;</span>
    <span class="nt">&lt;/body&gt;</span>
<span class="nt">&lt;/html&gt;</span>
</pre></div>
</div>
</li>
</ol>
<p>...and that is template inheritance in a nutshell. The main idea
is that the methods that you call upon <tt class="docutils literal"><span class="pre">self</span></tt> always
correspond to the topmost definition of that method. Very much
the way <tt class="docutils literal"><span class="pre">self</span></tt> works in a Python class, even though Mako is
not actually using Python class inheritance to implement this
functionality. (Mako doesn&#8217;t take the &#8220;inheritance&#8221; metaphor too
seriously; while useful to setup some commonly recognized
semantics, a textual template is not very much like an
object-oriented class construct in practice).</p>

<h2>Nesting Blocks<a class="headerlink" href="#nesting-blocks" title="Permalink to this headline"></a></h2>
<p>The named blocks defined in an inherited template can also be nested within
other blocks.  The name given to each block is globally accessible via any inheriting
template.  We can add a new block <tt class="docutils literal"><span class="pre">title</span></tt> to our <tt class="docutils literal"><span class="pre">header</span></tt> block:</p>

used in the base template both in the <tt class="docutils literal"><span class="pre">&lt;title&gt;</span></tt> section as well as the <tt class="docutils literal"><span class="pre">&lt;h2&gt;</span></tt>.</p>

<div class="section" id="but-what-about-defs">
<h2>But what about Defs?<a class="headerlink" href="#but-what-about-defs" title="Permalink to this headline"></a></h2>
<p>The previous example used the <tt class="docutils literal"><span class="pre">&lt;%block&gt;</span></tt> tag to produce areas of content
to be overridden.  Before Mako 0.4.1, there wasn&#8217;t any such tag &#8211; instead
there was only the <tt class="docutils literal"><span class="pre">&lt;%def&gt;</span></tt> tag.   As it turns out, named blocks and defs are
largely interchangeable.  The def simply doesn&#8217;t call itself automatically,
and has more open-ended naming and scoping rules that are more flexible and similar
to Python itself, but less suited towards layout.  The first example from
this chapter using defs would look like:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## index.html</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">inherit</span> <span class="na">file=</span><span class="s">&quot;base.html&quot;</span><span class="cp">/&gt;</span><span class="x"></span>

<span class="cp">&lt;%</span><span class="nb">def</span> <span class="na">name=</span><span class="s">&quot;header()&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">    this is some header content</span>
<span class="cp">&lt;/%</span><span class="nb">def</span><span class="cp">&gt;</span><span class="x"></span>

<span class="x">this is the body content.</span>
</pre></div>
</div>
<p>And <tt class="docutils literal"><span class="pre">base.html</span></tt>, the inherited template:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## base.html</span><span class="x"></span>
<span class="x">&lt;html&gt;</span>
<span class="x">    &lt;body&gt;</span>

<span class="cp">&lt;%</span><span class="nb">def</span> <span class="na">name=</span><span class="s">&quot;footer()&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">    this is the footer</span>
<span class="cp">&lt;/%</span><span class="nb">def</span><span class="cp">&gt;</span><span class="x"></span>
</pre></div>
</div>
<p>Above, we illustrate that defs differ from blocks in that their definition
and invocation are defined in two separate places, instead of at once. You can <em>almost</em> do exactly what a
block does if you put the two together:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="x">&lt;div class=&quot;header&quot;&gt;</span>
<span class="x">    </span><span class="cp">&lt;%</span><span class="nb">def</span> <span class="na">name=</span><span class="s">&quot;header()&quot;</span><span class="cp">&gt;&lt;/%</span><span class="nb">def</span><span class="cp">&gt;${</span><span class="bp">self</span><span class="o">.</span><span class="n">header</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>
<span class="x">&lt;/div&gt;</span>
</pre></div>
</div>
<p>The <tt class="docutils literal"><span class="pre">&lt;%block&gt;</span></tt> is obviously more streamlined than the <tt class="docutils literal"><span class="pre">&lt;%def&gt;</span></tt> for this kind
of usage.  In addition,
the above &#8220;inline&#8221; approach with <tt class="docutils literal"><span class="pre">&lt;%def&gt;</span></tt> does not work with nesting:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="x">&lt;head&gt;</span>
<span class="x">    </span><span class="cp">&lt;%</span><span class="nb">def</span> <span class="na">name=</span><span class="s">&quot;header()&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">        &lt;title&gt;</span>
<span class="x">        ## this won&#39;t work !</span>
<span class="x">        </span><span class="cp">&lt;%</span><span class="nb">def</span> <span class="na">name=</span><span class="s">&quot;title()&quot;</span><span class="cp">&gt;</span><span class="x">default title</span><span class="cp">&lt;/%</span><span class="nb">def</span><span class="cp">&gt;${</span><span class="bp">self</span><span class="o">.</span><span class="n">title</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>
<span class="x">        &lt;/title&gt;</span>
<span class="x">    </span><span class="cp">&lt;/%</span><span class="nb">def</span><span class="cp">&gt;${</span><span class="bp">self</span><span class="o">.</span><span class="n">header</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>
<span class="x">&lt;/head&gt;</span>
</pre></div>
</div>
<p>Where above, the <tt class="docutils literal"><span class="pre">title()</span></tt> def, because it&#8217;s a def within a def, is not part of the
template&#8217;s exported namespace and will not be part of <tt class="docutils literal"><span class="pre">self</span></tt>.  If the inherited template
did define its own <tt class="docutils literal"><span class="pre">title</span></tt> def at the top level, it would be called, but the &#8220;default title&#8221;
above is not present at all on <tt class="docutils literal"><span class="pre">self</span></tt> no matter what.  For this to work as expected
you&#8217;d instead need to say:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="x">&lt;head&gt;</span>
<span class="x">    </span><span class="cp">&lt;%</span><span class="nb">def</span> <span class="na">name=</span><span class="s">&quot;header()&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">        &lt;title&gt;</span>
<span class="x">        </span><span class="cp">${</span><span class="bp">self</span><span class="o">.</span><span class="n">title</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>
<span class="x">        &lt;/title&gt;</span>
<span class="x">    </span><span class="cp">&lt;/%</span><span class="nb">def</span><span class="cp">&gt;${</span><span class="bp">self</span><span class="o">.</span><span class="n">header</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>

<span class="x">    </span><span class="cp">&lt;%</span><span class="nb">def</span> <span class="na">name=</span><span class="s">&quot;title()&quot;</span><span class="cp">/&gt;</span><span class="x"></span>
<span class="x">&lt;/head&gt;</span>
</pre></div>
</div>
<p>That is, <tt class="docutils literal"><span class="pre">title</span></tt> is defined outside of any other defs so that it is in the <tt class="docutils literal"><span class="pre">self</span></tt> namespace.
It works, but the definition needs to be potentially far away from the point of render.</p>
<p>A named block is always placed in the <tt class="docutils literal"><span class="pre">self</span></tt> namespace, regardless of nesting,
so this restriction is lifted:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## base.html</span><span class="x"></span>
<span class="x">&lt;head&gt;</span>
<span class="x">    </span><span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;header&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">        &lt;title&gt;</span>
<span class="x">        </span><span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;title&quot;</span><span class="cp">/&gt;</span><span class="x"></span>
<span class="x">        &lt;/title&gt;</span>
<span class="x">    </span><span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">&lt;/head&gt;</span>
</pre></div>
</div>
<p>The above template defines <tt class="docutils literal"><span class="pre">title</span></tt> inside of <tt class="docutils literal"><span class="pre">header</span></tt>, and an inheriting template can define
one or both in <strong>any</strong> configuration, nested inside each other or not, in order for them to be used:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## index.html</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">inherit</span> <span class="na">file=</span><span class="s">&quot;base.html&quot;</span><span class="cp">/&gt;</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;title&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">    the title</span>
<span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;header&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">    the header</span>
<span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>
</pre></div>
</div>
<p>So while the <tt class="docutils literal"><span class="pre">&lt;%block&gt;</span></tt> tag lifts the restriction of nested blocks not being available externally,
in order to achieve this it <em>adds</em> the restriction that all block names in a single template need
to be globally unique within the template, and additionally that a <tt class="docutils literal"><span class="pre">&lt;%block&gt;</span></tt> can&#8217;t be defined
inside of a <tt class="docutils literal"><span class="pre">&lt;%def&gt;</span></tt>. It&#8217;s a more restricted tag suited towards a more specific use case than <tt class="docutils literal"><span class="pre">&lt;%def&gt;</span></tt>.</p>

<h2>Using the <tt class="docutils literal"><span class="pre">next</span></tt> Namespace to Produce Content Wrapping<a class="headerlink" href="#using-the-next-namespace-to-produce-content-wrapping" title="Permalink to this headline"></a></h2>
<p>Sometimes you have an inheritance chain that spans more than two
templates. Or maybe you don&#8217;t, but you&#8217;d like to build your
system such that extra inherited templates can be inserted in
the middle of a chain where they would be smoothly integrated.
If each template wants to define its layout just within its main
body, you can&#8217;t just call <tt class="docutils literal"><span class="pre">self.body()</span></tt> to get at the
inheriting template&#8217;s body, since that is only the topmost body.
To get at the body of the <em>next</em> template, you call upon the
namespace <tt class="docutils literal"><span class="pre">next</span></tt>, which is the namespace of the template
<strong>immediately following</strong> the current template.</p>
<p>Lets change the line in <tt class="docutils literal"><span class="pre">base.html</span></tt> which calls upon
<tt class="docutils literal"><span class="pre">self.body()</span></tt> to instead call upon <tt class="docutils literal"><span class="pre">next.body()</span></tt>:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## base.html</span><span class="x"></span>
<span class="x">&lt;html&gt;</span>
<span class="x">    &lt;body&gt;</span>
<span class="x">        &lt;div class=&quot;header&quot;&gt;</span>
<span class="x">            </span><span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;header&quot;</span><span class="cp">/&gt;</span><span class="x"></span>
<span class="x">        &lt;/div&gt;</span>

<span class="x">        </span><span class="cp">${</span><span class="nb">next</span><span class="o">.</span><span class="n">body</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>

<span class="x">        &lt;div class=&quot;footer&quot;&gt;</span>
<span class="x">            </span><span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;footer&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">                this is the footer</span>
<span class="x">            </span><span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>

<span class="x">    &lt;/body&gt;</span>
<span class="x">&lt;/html&gt;</span>
</pre></div>
</div>
<p>Lets also add an intermediate template called <tt class="docutils literal"><span class="pre">layout.html</span></tt>,
which inherits from <tt class="docutils literal"><span class="pre">base.html</span></tt>:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## layout.html</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">inherit</span> <span class="na">file=</span><span class="s">&quot;base.html&quot;</span><span class="cp">/&gt;</span><span class="x"></span>
<span class="x">&lt;ul&gt;</span>
<span class="x">    </span><span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;toolbar&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">        &lt;li&gt;selection 1&lt;/li&gt;</span>
<span class="x">        &lt;li&gt;selection 2&lt;/li&gt;</span>
<span class="x">        &lt;li&gt;selection 3&lt;/li&gt;</span>
<span class="x">    </span><span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">&lt;/ul&gt;</span>
<span class="x">&lt;div class=&quot;mainlayout&quot;&gt;</span>
<span class="x">    </span><span class="cp">${</span><span class="nb">next</span><span class="o">.</span><span class="n">body</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>
<span class="x">&lt;/div&gt;</span>
</pre></div>
</div>
<p>And finally change <tt class="docutils literal"><span class="pre">index.html</span></tt> to inherit from
<tt class="docutils literal"><span class="pre">layout.html</span></tt> instead:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## index.html</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">inherit</span> <span class="na">file=</span><span class="s">&quot;layout.html&quot;</span><span class="cp">/&gt;</span>

<span class="cp">## .. rest of template</span><span class="x"></span>
</pre></div>
</div>
<p>In this setup, each call to <tt class="docutils literal"><span class="pre">next.body()</span></tt> will render the body
of the next template in the inheritance chain (which can be
written as <tt class="docutils literal"><span class="pre">base.html</span> <span class="pre">-&gt;</span> <span class="pre">layout.html</span> <span class="pre">-&gt;</span> <span class="pre">index.html</span></tt>). Control
is still first passed to the bottommost template <tt class="docutils literal"><span class="pre">base.html</span></tt>,
and <tt class="docutils literal"><span class="pre">self</span></tt> still references the topmost definition of any
particular def.</p>
<p>The output we get would be:</p>
<div class="highlight-html"><div class="highlight"><pre><span class="nt">&lt;html&gt;</span>
    <span class="nt">&lt;body&gt;</span>
        <span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;header&quot;</span><span class="nt">&gt;</span>
            this is some header content
        <span class="nt">&lt;/div&gt;</span>

        <span class="nt">&lt;ul&gt;</span>
            <span class="nt">&lt;li&gt;</span>selection 1<span class="nt">&lt;/li&gt;</span>
            <span class="nt">&lt;li&gt;</span>selection 2<span class="nt">&lt;/li&gt;</span>
            <span class="nt">&lt;li&gt;</span>selection 3<span class="nt">&lt;/li&gt;</span>
        <span class="nt">&lt;/ul&gt;</span>

        <span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;mainlayout&quot;</span><span class="nt">&gt;</span>
        this is the body content.
        <span class="nt">&lt;/div&gt;</span>

        <span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;footer&quot;</span><span class="nt">&gt;</span>
            this is the footer
        <span class="nt">&lt;/div&gt;</span>
    <span class="nt">&lt;/body&gt;</span>
<span class="nt">&lt;/html&gt;</span>
</pre></div>
</div>
<p>So above, we have the <tt class="docutils literal"><span class="pre">&lt;html&gt;</span></tt>, <tt class="docutils literal"><span class="pre">&lt;body&gt;</span></tt> and
<tt class="docutils literal"><span class="pre">header</span></tt>/<tt class="docutils literal"><span class="pre">footer</span></tt> layout of <tt class="docutils literal"><span class="pre">base.html</span></tt>, we have the
<tt class="docutils literal"><span class="pre">&lt;ul&gt;</span></tt> and <tt class="docutils literal"><span class="pre">mainlayout</span></tt> section of <tt class="docutils literal"><span class="pre">layout.html</span></tt>, and the
main body of <tt class="docutils literal"><span class="pre">index.html</span></tt> as well as its overridden <tt class="docutils literal"><span class="pre">header</span></tt>
def. The <tt class="docutils literal"><span class="pre">layout.html</span></tt> template is inserted into the middle of
the chain without <tt class="docutils literal"><span class="pre">base.html</span></tt> having to change anything.
Without the <tt class="docutils literal"><span class="pre">next</span></tt> namespace, only the main body of
<tt class="docutils literal"><span class="pre">index.html</span></tt> could be used; there would be no way to call
<tt class="docutils literal"><span class="pre">layout.html</span></tt>&#8216;s body content.</p>
</div>
<div class="section" id="using-the-parent-namespace-to-augment-defs">
<span id="parent-namespace"></span><h2>Using the <tt class="docutils literal"><span class="pre">parent</span></tt> Namespace to Augment Defs<a class="headerlink" href="#using-the-parent-namespace-to-augment-defs" title="Permalink to this headline"></a></h2>
<p>Lets now look at the other inheritance-specific namespace, the
opposite of <tt class="docutils literal"><span class="pre">next</span></tt> called <tt class="docutils literal"><span class="pre">parent</span></tt>. <tt class="docutils literal"><span class="pre">parent</span></tt> is the
namespace of the template <strong>immediately preceding</strong> the current
template. What&#8217;s useful about this namespace is that
defs or blocks can call upon their overridden versions.
This is not as hard as it sounds and
is very much like using the <tt class="docutils literal"><span class="pre">super</span></tt> keyword in Python. Lets
modify <tt class="docutils literal"><span class="pre">index.html</span></tt> to augment the list of selections provided
by the <tt class="docutils literal"><span class="pre">toolbar</span></tt> function in <tt class="docutils literal"><span class="pre">layout.html</span></tt>:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">## index.html</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">inherit</span> <span class="na">file=</span><span class="s">&quot;layout.html&quot;</span><span class="cp">/&gt;</span><span class="x"></span>

<span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;header&quot;</span><span class="cp">&gt;</span><span class="x"></span>
<span class="x">    this is some header content</span>
<span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>

<span class="cp">&lt;%</span><span class="nb">block</span> <span class="na">name=</span><span class="s">&quot;toolbar&quot;</span><span class="cp">&gt;</span>
    <span class="cp">## call the parent&#39;s toolbar first</span><span class="x"></span>
<span class="x">    </span><span class="cp">${</span><span class="n">parent</span><span class="o">.</span><span class="n">toolbar</span><span class="p">()</span><span class="cp">}</span><span class="x"></span>
<span class="x">    &lt;li&gt;selection 4&lt;/li&gt;</span>
<span class="x">    &lt;li&gt;selection 5&lt;/li&gt;</span>
<span class="cp">&lt;/%</span><span class="nb">block</span><span class="cp">&gt;</span><span class="x"></span>

<span class="x">this is the body content.</span>
</pre></div>
</div>
<p>Above, we implemented a <tt class="docutils literal"><span class="pre">toolbar()</span></tt> function, which is meant
to override the definition of <tt class="docutils literal"><span class="pre">toolbar</span></tt> within the inherited
template <tt class="docutils literal"><span class="pre">layout.html</span></tt>. However, since we want the content
from that of <tt class="docutils literal"><span class="pre">layout.html</span></tt> as well, we call it via the
<tt class="docutils literal"><span class="pre">parent</span></tt> namespace whenever we want it&#8217;s content, in this case
before we add our own selections. So the output for the whole
thing is now:</p>
<div class="highlight-html"><div class="highlight"><pre><span class="nt">&lt;html&gt;</span>
    <span class="nt">&lt;body&gt;</span>
        <span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;header&quot;</span><span class="nt">&gt;</span>
            this is some header content
        <span class="nt">&lt;/div&gt;</span>

        <span class="nt">&lt;ul&gt;</span>
            <span class="nt">&lt;li&gt;</span>selection 1<span class="nt">&lt;/li&gt;</span>
            <span class="nt">&lt;li&gt;</span>selection 2<span class="nt">&lt;/li&gt;</span>
            <span class="nt">&lt;li&gt;</span>selection 3<span class="nt">&lt;/li&gt;</span>
            <span class="nt">&lt;li&gt;</span>selection 4<span class="nt">&lt;/li&gt;</span>
            <span class="nt">&lt;li&gt;</span>selection 5<span class="nt">&lt;/li&gt;</span>
        <span class="nt">&lt;/ul&gt;</span>

        <span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;mainlayout&quot;</span><span class="nt">&gt;</span>
        this is the body content.
        <span class="nt">&lt;/div&gt;</span>

        <span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;footer&quot;</span><span class="nt">&gt;</span>
            this is the footer
        <span class="nt">&lt;/div&gt;</span>
    <span class="nt">&lt;/body&gt;</span>
<span class="nt">&lt;/html&gt;</span>
</pre></div>
</div>
<p>and you&#8217;re now a template inheritance ninja!</p>

<div class="section" id="inheritable-attributes">

<p>The <a class="reference internal" href="namespaces.html#mako.runtime.Namespace.attr" title="mako.runtime.Namespace.attr"><tt class="xref py py-attr docutils literal"><span class="pre">attr</span></tt></a> accessor of the <a class="reference internal" href="namespaces.html#mako.runtime.Namespace" title="mako.runtime.Namespace"><tt class="xref py py-class docutils literal"><span class="pre">Namespace</span></tt></a> object
allows access to module level variables declared in a template. By accessing
<tt class="docutils literal"><span class="pre">self.attr</span></tt>, you can access regular attributes from the
inheritance chain as declared in <tt class="docutils literal"><span class="pre">&lt;%!</span> <span class="pre">%&gt;</span></tt> sections. Such as:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">&lt;%!</span>
    <span class="n">class_</span> <span class="o">=</span> <span class="s">&quot;grey&quot;</span>

<span class="x">&lt;div class=&quot;</span><span class="cp">${</span><span class="bp">self</span><span class="o">.</span><span class="n">attr</span><span class="o">.</span><span class="n">class_</span><span class="cp">}</span><span class="x">&quot;&gt;</span>

<span class="x">&lt;/div&gt;</span>
</pre></div>
</div>
<p>If an inheriting template overrides <tt class="docutils literal"><span class="pre">class_</span></tt> to be
<tt class="docutils literal"><span class="pre">&quot;white&quot;</span></tt>, as in:</p>
<div class="highlight-mako"><div class="highlight"><pre><span class="cp">&lt;%!</span>
    <span class="n">class_</span> <span class="o">=</span> <span class="s">&quot;white&quot;</span>
<span class="cp">%&gt;</span><span class="x"></span>
<span class="cp">&lt;%</span><span class="nb">inherit</span> <span class="na">file=</span><span class="s">&quot;parent.html&quot;</span><span class="cp">/&gt;</span><span class="x"></span>

<span class="x">This is the body</span>
</pre></div>
</div>
<p>you&#8217;ll get output like:</p>
<div class="highlight-html"><div class="highlight"><pre><span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;white&quot;</span><span class="nt">&gt;</span>
