    <p>For 2 child template files inheriting a block, the <code>{{ block.super }}</code> does not resolve</p> <p>Python 2.5.2, Django 1.0, Windows XP SP3</p> <p>Sample skeleton code for files involved:</p> <ol> <li><code>base.html</code></li> <li><code>item_base.html</code></li> <li><code>show_info_for_all_items.html</code></li> <li><code>show_info_for_single_item.html</code></li> </ol> <p>FILE : <code>base.html</code></p> <pre><code>{% block content %} {% endblock %} </code></pre> <p>FILE : <code>item_base.html</code></p> <pre><code>{% extends "base.html" %} {% block item_info %} Item : {{ item.name }}&lt;br/&gt; Price : {{ item.price }}&lt;br/&gt; {% endblock %} </code></pre> <p>FILE : <code>show_info_for_all_items.html</code></p> <pre><code>{% extends "item_base.html" %} {% block content %} &lt;h1&gt;info on all items&lt;/h1&gt; &lt;hr/&gt; {% for item in items %} {% block item_info %} {{ block.super }} {% endblock %} &lt;hr/&gt; {% endfor %} {% endblock %} </code></pre> <p>FILE : <code>show_info_for_single_item.html</code></p> <pre><code>{% extends "item_base.html" %} {% block content %} &lt;h1&gt;info on single item&lt;/h1&gt; {% block item_info %} {{ block.super }} {% endblock %} {% endblock %} </code></pre> <p><code>show_info_for_all_items.html</code> shows a list of items along with each item's info.</p> <p><code>show_info_for_single_item.html</code> shows a single item with the item's info.</p> <p><code>show_info_for_all_items.html</code> and <code>show_info_for_single_item.html</code> share same code for showing item info, so I moved it to <code>item_base.html</code> into <code>block item_info</code></p> <p>but the <code>{{ block.super }}</code> in <code>show_info_for_all_items.html</code> and <code>show_info_for_single_item.html</code> does not work. <code>{{ block.super }}</code> resolves as blank.</p> <p>If I move the code back from <code>block item_info</code> in <code>item_base.html</code> into <code>show_info_for_all_items.html</code> and <code>show_info_for_single_item.html</code> it works but then I have to duplicate same <code>block item_info</code> code in 2 files.</p> <p>If the block.super issue can not be solved, does Django offer something like INCLUDE => <code>{% INCLUDE "item_base.html" %}</code> so blocks from a template file can be included ( instead of <code>extends</code> )</p> <p>How do I avoid duplicating <code>block item_info</code> in both html files?</p>

    3. CONo, I will *not* embrace Help Vampires, and I do not agree with those who encourage them here. SO cannot and, IMNSHO, *should not try to* replace the high quality docs of a project like Django. Thinking that SO can and should is arrogance, plain and simple.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
