    <p>You can solve the problem with a template filter:</p> <ol> <li><p>Create a file for the filters (i.e. <code>&lt;YOUR_APP&gt;/templatetags/&lt;YOUR_FILTERS&gt;.py</code>) and add following code:</p> <pre><code>from django.template import Library from django.utils.datetime_safe import datetime register = Library() @register.filter def full_month_price_list(value): month_list = [[datetime(2013, i, 1)] for i in xrange(1, 13)] for item in value: month_list[item.date.month - 1].append(item) return month_list </code></pre> <p>This filter takes the list of items with a date attribute and returns a list with 12 lists of 2 elements: the date and the item</p></li> <li><p>In your template code load the filters (<code>{% load &lt;YOUR_FILTERS&gt; %}</code>) and change this:</p> <pre><code>&lt;ul&gt; {% for item in product.list|dictsort:"date" %} &lt;li&gt;{{ item.price }} - {{ item.date|date }}&lt;/li&gt; {% endfor %} &lt;/ul&gt; </code></pre> <p>by (<strong>UPDATED to format as table as you request in comments</strong>):</p> <pre><code>&lt;table&gt; {% for item in product.list|full_month_price_list %} &lt;tr&gt; &lt;td&gt;{{ item.0|date:"b. j, Y" }}&lt;/td&gt; &lt;td&gt;{{ item.1.price|default:"MISSING VALUE" }}&lt;/td&gt; &lt;/tr&gt; {% endfor %} &lt;/table&gt; </code></pre> <p>Note that you access to any property of the product <code>item.1.date</code>, <code>item.1.price</code>, <code>item.1.pk</code>, etc.</p></li> </ol> <p>Replacing <code>&lt;YOUR_APP&gt;</code> by the name of your django app, <code>&lt;YOUR_FILTERS&gt;</code> by the name you want to use for your filters file.</p> <p>Note that a file named <code>__init__.py</code> is needed in the directory <code>&lt;YOUR_APP&gt;/templatetags/</code>.</p> <p>More about custom filters in <a href="http://docs.djangoproject.com/en/1.6/howto/custom-template-tags/" rel="nofollow">django docs</a>.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
